The human body is made of many different components. These include bones, muscle tissue, blood, water and gases such as oxygen and hydrogen. The body is one of the most complex machines ever made as it is kept in working order by a series of vital organs including the heart, lungs, kidneys, bowels and brain. Without all these components, the body may not be able to function at its full capability.
Each day a human being will breathe in a number of different gases from the natural environment. Part of these essential gases will include oxygen. This will be breathed in through the lungs and then passed around the body through the blood stream. The heart pumps the blood to different muscles and organs at an incredibly fast rate. It is the oxygen that helps the muscles and body move.
The skeleton is what gives the body its shape and what protects the vital organs. Without bones or a skeleton, the human body would just be a big lump of fat and muscles. We would be unable to move and would be at risk of serious diseases and even death. We would probably even be unable to keep breathing ourselves as there would be no rib cage to protect the lungs.
The skin is often regarded as one of the biggest and most important organs in the body. It covers the whole surface area keeping the bones, muscles and vital organs safe. The pores on the skin are what help the body from overheating and drying out.
