Body systems ........(for information use only)
Our bodies consist of a number of biological systems that carry out specific functions necessary for everyday living.
....The job of the circulatory system is to move blood, nutrients, oxygen, carbon dioxide, and hormones, around the body. It consists of the heart, blood, blood vessels,arteries and veins.
....The digestive system consists of a series of connected organs that together, allow the body to break down and absorb food, and remove waste.
....The immune system is the body's defense against bacteria, viruses and other pathogens that may be harmful.
.....The nervous system controls both voluntary action (like conscious movement) and involuntary actions (like breathing), and sends signals to different parts of the body.
......The body's muscular system consists of about 650 muscles that aid in movement, blood flow and other bodily functions.
......The reproductive system allows humans to reproduce.
......The respiratory system allows us to take in vital oxygen and expel carbon dioxide in a process we call breathing. It consists mainly of the trachea, the diaphragm and the lungs.
Humans have five vital organs that are essential for survival. These are the brain, heart, kidneys, liver and lungs.
.....The human brain is the body's control center, receiving and sending signals to other organs through the nervous system and through secreted hormones. It is responsible for our thoughts, feelings, memory storage and general perception of the world.
......The human heart is a responsible for pumping blood throughout our body.
......The job of the kidneys is to remove waste and extra fluid from the blood. The kidneys take urea out of the blood and combine it with water and other substances to make urine.
.......The liver has many functions, including detoxifying of harmful chemicals, breakdown of drugs, filtering of blood, secretion of bile and production of blood-clotting proteins.
.......The lungs are responsible for removing oxygen from the air we breathe and transferring it to our blood where it can be sent to our cells. The lungs also remove carbon dioxide, which we exhale.
