primäärikierto

Primäärikierto refers to the primary circulation of blood within the body. This encompasses the systemic circulation, which delivers oxygenated blood from the left ventricle of the heart to the rest of the body, and the pulmonary circulation, which transports deoxygenated blood from the right ventricle to the lungs for oxygenation and then returns it to the left atrium. Together, these two circuits ensure that all tissues and organs receive the necessary oxygen and nutrients, while waste products are removed. The heart acts as the central pump, driving this continuous flow through a network of arteries, veins, and capillaries. The pressure generated by the heart's contractions, along with the elasticity of blood vessels, maintains the unidirectional movement of blood. Disruptions to primäärikierto can lead to various cardiovascular conditions, highlighting its critical role in maintaining overall health.
