Human Body Systems

We have been reviewing the human body systems and their functions. It is important to remember that the function is what is does and the structure is what it looks like. The human body is designed so that the structure meets the function. For instance, remember when I made you turn your tables sideways and upside down to show that they were not designed to work that way. Our body is the same in that we need certain structures to meet certain functions. For example, the heart has four chambers because the blood has to be sent to the lungs for oxygen and then back to the heart to be sent throughout the body. The chambers help hold the blood for it to go to the next area. The heart is also made of thick cardiac muscle because it has to pump very often and to far away areas. I have attached some websites that will help you review the systems.
