What is Physiology?
Physiology is the study of how molecules, organs and cell interact with each other. The cardiovascular system has three main functions. The cardiovascular system is a very complex system its in a constant change and transformation.
Blood vessels are the body’s highways that allow blood to flow quickly and efficiently from the heart to every region of the body and back again. The size of blood vessels corresponds with the amount of blood that passes through the vessel. All blood vessels contain a hollow area called the lumen through which blood is able to flow. Around the lumen is the wall of the vessel, which may be thin in the case of capillaries or very thick in the case of arteries.
