The Cardiovascular System.
Major functions of the
cardiovascular system
The Cardiovascular system consists of blood, blood vessels and the heart.
Transports nutrients, oxygen, and hormones to cells throughout the body
Removes the metabolic wastes such as carbon dioxide and nitrogenous wastes
Protects the body from blood loss and infection.
Maintains a constant body temperature
Helps maintain fluid balance within the body
Blood flow through the heart and body

Structural and functional differences between blood vessel types
atria: thin walled collecting chambers
ventricles: Thick, muscular pumping chambers L and R sides separated by interatrial or inter interventricular
Septum: 4 valves of the heart
atrioventricular valves: after atria
semilunar valves: after ventricles
Pulmonary: comes before lungs
Aortic: comes before aorta
