systemic circulation
Học thuậtThân thiện
Blood flows from the heart through the systemic circulation to deliver oxygen to the muscles.
Definition
Noun: - The part of the cardiovascular system which carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart: This refers to the loop of blood flow that delivers oxygen and nutrients to the body's tissues and organs (the systemic circuit) and brings back carbon dioxide and other waste products. It is distinguished from pulmonary circulation, which is the circuit to and from the lungs.
