The Human Heart
The human heart is an amazing organ of the human body. The heart is an organ which pumps life-giving blood throughout the body. It works together with blood and blood vessels to supply all of the needs of the cells.
The heart is located in the middle of the chest and slightly to the left. It is divided into two halves and has two hollow spaces or chambers. The blood enters the atria, which is the upper chamber and is then pumped to the ventricles, two lower chambers. Blood from the ventricles goes to the lungs and to every cell in the body. [A]
An artery is a blood vessel which carries blood away from the heart. A main artery may be as thick as a thumb. Blood is made up of red cells, white cells and platelets floating in a fluid called plasma. Plasma is a liquid and can easily pass through small blood vessels into cells and makes up over one-half of the blood. The plasma carries nutrients (food) from the stomach to be used as fuel for energy. Plasma also helps keep the body warm.
The blood then returns to the heart through blood vessels called veins. The veins on the skin, may look blue, especially on the hands and arms. The walls of a vein are much thinner than those of an artery. Two large veins bring the blood back to the heart. One comes from the brain and the chest. The other comes from the stomach and lower body. [B]
Blood doesn't flow at the same speed through all of the body. As it gets farther away from the heart, it slows down. It goes slowly when the red blood cells carrying the food and oxygen squeeze through into the cells. [C]
The heart beats or pumps every second of the day or night. It beats or pumps 100,000 times a day, every day of a person's life. Every time a heart beats or pumps out a stream of blood, this beat, called a pulse, can be felt on the inside of the wrist. The pulse rate in an adult is between sixty and one hundred beats per minute. Children's pulse rates range from ninety to one hundred twenty beats per minute. [D]
In summary, the circulatory system which includes the heart, blood vessels and blood, work together to supply the cells with all the food and oxygen a body needs to maintain life. Blood is made up of red cells, white cells and platelets floating in a fluid called plasma. Arteries carry blood away from the heart, and veins carry the blood back to the heart. The heart beats thousands of times a day, every day. It beats much faster in children. The human heart is an amazing organ which is part of a system of many veins, arteries, and vessels which moves blood throughout the body keeping humans alive.

The five senses of the body include sight, hearing, taste, smell, and touch. Human beings and most other animals use the five senses to help them live and experience the world around them. The senses also help people to learn, protect themselves, and to enjoy the differences between foods, sounds, and other experiences a person has in life. The senses also work together to give you a clear picture of the activities around you.
The first sense is sight, which depends on the eyes. People use their eyes to see the people, objects, and other items around them. Of course, the sense of sight is also helpful for reading, traveling, driving, and moving from place to place each day. Inside the eye there are special lenses that take in light to help people see things. If it is too dark, a person will have trouble seeing. The eyes can also adjust to the amount of light available. Many people, though, young and old, may also need glasses to help them see clearly. Some people may be able to see things up close, but not far away, which means they are nearsighted. If a person can see far away but not up close, they are farsighted. If a person is blind, there are special books written in braille which helps them feel the raised letters. Some blind people also have special dogs to help guide them from place to place in their home and when they go places.
The second sense, hearing, depends on the ears. There are actually three parts of the ear, the outer ear, middle ear, and the inner ear. The outer ear is the part other people can see. The outer ear catches the sound waves as they travel to the person and then sends them into the ear. The outer ear acts like a funnel collecting the different sounds a person experiences. The middle ear contains the eardrum and several bones which transfers sound from the outer ear to the inner ear. The inner ear consists of tubes and passages that takes the sound vibrations and sends them to your brain for understanding. [A]
The third sense, smell, depends on your nose. Inside the nose there is a substance that takes the fumes of an odor and then sends it to the brain. If a person gets a cold the sense of smell may not be as strong. The nose also helps clean the air a person breathes by filtering it. Inside the nose there are tiny hairs, called cilia, which act as cleaners to help keep substances in the air from entering a person's body through the nose. In addition, the nose affects the way a person speaks. If a person holds their nose while speaking, their voice will sound different. Smell also helps with the sense of taste. As a person tastes the food in their mouth, the aroma of the food enters a person's nose. [B]
The next sense, feeling, or touch, can be experienced throughout the entire body through a person's skin. Some parts of the body are more sensitive to touch than other parts. The skin has parts in it that collect information and sends it the brain. Most of a person's feeling is done by the hands. In addition, when a person has a stomach ache or feel other kinds of pain, the sense of touch is working from inside the body. [C]
The final sense, taste, comes from the taste buds on a person's tongue. As stated earlier, the sense of smell also affects the sense of taste. The tongue tastes four different flavors: salty, sweet, sour, and bitter. Many foods a person eats may be a combination of the four main flavors. The tongue can also feel whether something in a person's mouth is hot, cold, creamy, crunchy, or dry.
In summary, the five senses are sight, hearing, smell, feeling, and taste. [D]

Of course, the sense of sight is also helpful for reading, traveling, driving, and moving from place to place each day. Inside the eye there are special lenses that take in light to help people see things. If it is too dark, a person will have trouble seeing. The eyes can also adjust to the amount of light available. Many people, though, young and old, may also need glasses to help them see clearly. Some people may be able to see things up close, but not far away, which means they are nearsighted. If a person can see far away but not up close, they are farsighted. If a person is blind, there are special books written in braille which helps them feel the raised letters. Some blind people also have special dogs to help guide them from place to place in their home and when they go places.
The second sense, hearing, depends on the ears. There are actually three parts of the ear, the outer ear, middle ear, and the inner ear. The outer ear is the part other people can see. The outer ear catches the sound waves as they travel to the person and then sends them into the ear. The outer ear acts like a funnel collecting the different sounds a person experiences. The middle ear contains the eardrum and several bones which transfers sound from the outer ear to the inner ear. The inner ear consists of tubes and passages that takes the sound vibrations and sends them to your brain for understanding. [A]
The third sense, smell, depends on your nose. Inside the nose there is a substance that takes the fumes of an odor and then sends it to the brain. If a person gets a cold the sense of smell may not be as strong. The nose also helps clean the air a person breathes by filtering it. Inside the nose there are tiny hairs, called cilia, which act as cleaners to help keep substances in the air from entering a person's body through the nose. In addition, the nose affects the way a person speaks. If a person holds their nose while speaking, their voice will sound different. Smell also helps with the sense of taste. As a person tastes the food in their mouth, the aroma of the food enters a person's nose. [B]
The next sense, feeling, or touch, can be experienced throughout the entire body through a person's skin. Some parts of the body are more sensitive to touch than other parts. The skin has parts in it that collect information and sends it the brain. Most of a person's feeling is done by the hands. In addition, when a person has a stomach ache or feel other kinds of pain, the sense of touch is working from inside the body. [C]
The final sense, taste, comes from the taste buds on a person's tongue. As stated earlier, the sense of smell also affects the sense of taste. The tongue tastes four different flavors: salty, sweet, sour, and bitter. Many foods a person eats may be a combination of the four main flavors. The tongue can also feel whether something in a person's mouth is hot, cold, creamy, crunchy, or dry.
In summary, the five senses are sight, hearing, smell, feeling, and taste. [D]

The five senses of the body include sight, hearing, taste, smell, and touch. Human beings and most other animals use the five senses to help them live and experience the world around them. The senses also help people to learn, protect themselves, and to enjoy the differences between foods, sounds, and other experiences a person has in life. The senses also work together to give you a clear picture of the activities around you.

Bones support the human body. They are the structure on which the skin hangs. Without bones the body would collapse. A person could not walk or run. Bones provide both support and protection for parts of the body.
In the front of the body the bony rib cage covers the chest. Underneath are the heart and lungs. The ribs are bones which protect the heart, lungs and stomach in case of injury. The skull protects the brain. The bones in the back (or spine) protect the nerves of the spinal column. [A]
The bones store minerals needed by other parts of the body. When the minerals are needed, they will be released into the blood. They also form new red and white blood cells each day. New bone is still made until a person reaches the age of thirty-five. When a person gets much older, the bones start to weaken. The minerals begin to disappear from the bones.
Besides storing minerals and forming blood cells, the bones work with muscles and joints. They allow movement in the body. The place where two bones come together is called a joint. The knee joint is the biggest and strongest joint in the body. Ligaments link bones together at the joints. They are very strong and can stretch. Muscles are attached to bones by tendons. The muscles and tendons together allow the bones move. [B]
The whole bone structure of the body is called the skeleton. The skull protects the brain, eyes, face, jaw and ears. Vertebrae make up the column of bones running down the back. Between each vertebra is a small cushion called a disk. The vertebrae are hollow. Nerves run down through the hollow parts to the whole body.
Knees, hands, feet and legs all have different kinds of bones. Some of these bones can move freely. Some are bound tightly together. Arm bones are connected at the top to the collarbone and shoulder bone. They are connected at the bottom to the hand. Leg bones are attached to the spine at the top by the group of bones called the pelvis. The upper part of the leg is the thigh bone. It forms part of the knee. The lower part of the leg is made up of two bones. They are attached to the foot at the bottom. [C]
Bones are actually living cells. The bones grow and change over time. A person is born with three hundred bones. Some of these bones can join together. By the time a person becomes an adult, he will have only about two hundred and six bones.
In summary, bones are a necessary part of the body. They provide protection and support for the vital organs, like the heart, brain and lungs. The bones are strong and can handle heavy weights. They allow a person to walk. They work with muscles to help the body move and stretch. [D]

Bacteria are the second smallest living things on Earth with only viruses being smaller. They are very small organisms which usually consist of only a single cell. They do not have chlorophyll that is found in plants which allow for the production of food. If one million of the tiny bacteria were laid end-to-end, they would only measure about two inches. The word bacteria is plural, and bacterium describes a single organism.
An amateur scientist named Anton van Leeuwenhoek was the first person to see bacteria and other tiny organisms under a microscope. Though tiny, they are found everywhere. Bacteria is found in the air, soil, and water, as well as inside and outside of the human body. They reproduce quickly if the conditions are right. Millions of the tiny organisms can form in a space as small as a drop of water.
[A] Bacteria are usually placed in three categories depending on their shapes. The can be described a spherical (like a football), rod-like, or shaped like a spiral or corkscrew. There are also some bacteria shaped like a comma used in writing, but much smaller. There is helpful bacteria and harmful bacteria. Some can improve human life, but others can cause diseases. In addition, there are many more that simply have no effect on humans.
[B] The helpful bacteria assist with the digestion of foods in several kinds of animals including cows, deer, sheep and others. The bacteria help break down some of the foods the animals eat. In humans, a bacteria called E. coli also occur in the digestive system breaking down many kinds of foods. It is responsible for producing vitamin K and certain b vitamins.
[C] Other bacteria are decomposers in the food chain, which attack dead animals and break them down. They are then used as nutrients by plants. Bacteria is also part of the production of many foods eaten by people. Bacteria causes milk to become sour which helps in the production of buttermilk, cottage cheese, and yogurt.

[D] It can directly attack the tissues in a plant or animal. Sometimes fruits or vegetables become discolored due the attack by bacteria. Bacteria can also cause harm organisms by releasing chemicals that are poisonous to plants and animals. One type is responsible for a disease known as tetanus, which can paralyze the muscles of a person. The condition when this occurs is called lockjaw. Finally, the worst type of food poisoning is caused by a bacterium releasing a toxin. This type of food poisoning is called botulism.
There are also harmful bacteria living on the skin, but are not dangerous unless they enter the bloodstream through a cut in the skin. If E. coli, though helpful with digestion, enters the bloodstream it can cause cramping, diarrhea and maybe even death.
Methods to destroy bacteria include freezing and drying during food preservation or through pasteurization, which is the process of heating food to a specific temperature for a period of time. This is how bacteria are killed during the processing of milk.
In summary, bacteria are everywhere and can be harmful or helpful to humans and other organisms.
