The circulatory system is an organ system that passes nutrients, gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases and help stabilize body temperature and pH to maintain homeostasis.
The human circulatory system is responsible for delivering food, oxygen, and other needed substances to all cells in all parts of the body while taking away waste products
Circulatory system is divided into two types. They are systemic circulation and Coronary circulation.These are the explanation ;
A. SYSTEMIC CIRCULATION
Systemic circulation is the portion of the cardiovascular system which carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.
B. CORONARY CIRCULATION
Coronary circulation is the circulation of blood in the blood vessels of the heart muscle.
There is also the most important organ for circulatory system. That is heart. Heart is responsible for pumping blood throughout the blood vessels by repeated, rhythmic contractions.The vertebrate heart is composed of cardiac muscle, which is an involuntary striated muscle tissue found only within this organ.
