General Facts about the human body. Our heart beats 100,000 times a day. Our hearts is on a 60,000 and our eyes can distinguish up to a million colors surfaces and take in more information than any world greatest telescope. Our lungs inhale over two million liters of air every day without in spite of unusual sounds of any sort. Our sense of touch is more amazing than any tool created. Our brain is more complicated than the most powerful computer and has over 100 billion never cells. Everyones body give birth to 100 billion red cells´╗┐ everyday. Also when we touch things we send a message to our brain at 124mph. The human body also have over 600 muscles.

Scientists says the higher your I.Q. The more you dream, The largest cell in the human body is the female egg, the smallest is the male sperm. It takes the food seven seconds to get from your mouth to your stomach.The size of a bladder is the size of a softball. Why do we bleed? Because our bodies carries oxygen around our bodies to the body's cell , and pick up waste materials to take out of the body. When we breathe , the body takes in the oxygen that it needs and removes the carbon dioxide that it doesn't need.

What is Digestive?

The digestive system is made up of the digestive track a series of hollow organs joined in a long, twisting tube from the mouth to the anus and other organs that help the body break down and absorb food. The digestion involves mixing food with digestive juice, moving it through the digestive track and breaking large molecules of food into smaller molecules.The Digestion is also the breaking down of food into forms that our bodies can use. Our bodies uses food as fuel to provide energy for work, play and growth.

The digestive glands that act first are in the mouth the salivary glands. Saliva produced by these glands contains an enzyme that begins to digest the starch from food into smaller molecules. An enzyme is a substance that speeds up chemical reactions in the body. The digestive carbohydrates starch and sugar and broken into simpler molecules by enzymes in the Saliva, in the juice produced by the pancreas , and in the lining of the small intestine

What is Respiratory?
´╗┐
Your respiratory system is made up of the organs in your body that help you to breathe always remember, that Respiration = Breathing. The goal of breathing is to deliver oxygen to the body and take away carbon dioxide. The lungs are the main organs of the respiratory system. In the lungs oxygen is taken into the body and carbon dioxide is breathed out. The red blood cells are responsible for picking up the oxygen in the lungs and carrying the oxygen t all the body cells that need it.

Trachea which is also known as the windpipe this is the tube which carries air from the throat into the lungs. It ranges from 20-25mm in diameter and 10-16 cm in length.The inner membrane of the trachea is covered in tiny hairs called cillia, which catch particles of dust which we can then remove through coughing. The trachea is surrounded by 15-20 C shaped rings of cartilage at the front and side which help protect the trachea and keep it open.

What is the Circulatory System made up of?

The Circulatory System is made up of the vessels and the muscles that help and control the flow of the blood around the body.As the blood beings to circulate, it leaves the heart from the left ventricle and goes into the aorta. The aorta is the largest artery in the body.The leaving the aorta is full of oxygen. This is important for the cells in the brain and the body to do their work.Oxygen rich blood travels throughout the body in its system of aarteries into te smallest artrioles.

The Circulatry System is the main transportation and cooling system for the body. The Red Blood Cells act like billions of little UPS trucks carrying all sorts of packages that are needed by all the cells in the by all the cells in the body. Instead of UPS, Ill call them RBC's. RBC' carry oxygen and nutriets to the cells.

´╗┐Nervous System

Your nervous system is te control and communication system of the body. Its job is to send and receive messages. Your nervous system controls all your thoughts and movements. Th brain is he command center of your entire body. The brain is the bodys main information center. It is made of billions of neurons.The brain helps the body respond to the inforation it receieves from the sense.

The Spinal Cord is a tube of neurons that runs up the spine and attaches to the brain stem. Information from nerves that branch out to the rest of the body goes to the spinal cord. Some messages are processed by the spinal cord but most infomation is sent on to the brain.

Muscular System

The muscles we have in our body are divided into three classes of muscles ,cardic, smooth, and skeletal Ususally, when we think of muscular system we often only remember the skeletal muscles because they make up what is recognzed as the muscular sysem.

The muscular system is an extensive network of muscle and nervous tissue which is spread throughout the body. It i controlled by the central nervous system, which sends out an assortment of signals to keep the body running smoothly.There are over 650 muscles active in the human body, and the muscles system can comprise up to 40% of someones weight.

Skeletal System

Skeletal system determines the shap of the body, and protects the organs. It works closely together with th muscular system t allow us to move. The skeletal system is made up of your bones, ligaments, and tendons. It determines the shape and symmtry of the body, acts as a protective devices for your organs, act as a firm base for the attachments of muscles without bones, your muscles would not function properly. and the marrow tissues in the cavity of the bones produces red cells and some white cells, required in your blood.

Your skeleton also helps protect your internal organs and fragile body tissues. The brain,eyes,heart,lungs and spinal cord are al protected by your skeleton. Your cranium skull protects your brain and eyes, the ribs protect your heart and lungs and your vertebrae spine, backbones protect your spinal cord.
