Flashcards

Circulation

The movement of blood through the body's vessels, powered by the heart's pumping action, delivering nutrients and oxygen while removing waste.

Pulmonary Circulation

The system transporting de-oxygenated blood from the heart to the lungs for oxygenation, before it enters systemic circulation.

Systemic Circulation

The system that supplies oxygenated blood to all body tissues, delivering nutrients and removing carbon dioxide and waste.

Study Notes

Circulation is the movement of blood through the body's vessels.
Circulation is driven by the heart's pumping action.
Circulation distributes nutrients and oxygen to all body parts.
Circulation removes waste products from all parts of the body.

Pulmonary Circulation

Pulmonary circulation is a system that transports blood.
De-oxygenated blood is shunted from the heart to the lungs.
Blood is re-saturated with oxygen in the lungs.
Blood is dispersed into the systemic circulation after oxygenation.
Deoxygenated blood from the body's lower half enters the heart via the inferior vena cava.

Systemic Circulation

Systemic circulation provides the functional blood supply to all body tissue.
Oxygen and nutrients are carried to the cells.
Carbon dioxide and waste products are picked up.
Oxygenated blood flows from the left ventricle, through the arteries, to the capillaries in the body tissues.
