The circulatory system uses the channel of blood vessels to deliver blood to all parts of the body. This is a result of the left and right sides of the heart working together to allow blood to flow continuously to the lungs and other parts of the body. Oxygen-poor blood enters the right side of the heart through two large veins.
The main functions of the microcirculation are the delivery of oxygen and nutrients and the removal of carbon dioxide (CO 2). It also serves to regulate blood flow and tissue perfusion, thereby affecting blood pressure and responses to inflammation which can include edema (swelling).
The digestive system also works with the circulatory system to provide the nutrients the system needs to keep the heart pumping. [10] Further circulatory routes are associated, such as the coronary circulation to the heart itself, the cerebral circulation to the brain, renal circulation to the kidneys, and bronchial circulation to the bronchi ...

The cardiovascular system incorporates the heart blood vessels and lymphatic vessels. The main purpose is to maintain adequate blood circulation and hence the distribution of nutrients to tissues and the delivery of metabolic wastes to excretory / urinary organs.
Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.
