vérkeringés

Vérkeringés refers to the circulatory system in Hungarian. It is the biological system that transports nutrients, oxygen, antibodies, and other essential elements throughout the body and removes waste products like carbon dioxide. The primary organ responsible for driving this circulation is the heart, which acts as a pump. The system consists of two main interconnected circuits: the pulmonary circulation and the systemic circulation.

Pulmonary circulation is the pathway where blood travels from the heart to the lungs and back. In the lungs, blood releases carbon dioxide and picks up oxygen. Systemic circulation, on the other hand, distributes oxygenated blood from the heart to the rest of the body's tissues and organs. Deoxygenated blood, carrying waste products, then returns to the heart.

The circulatory system is comprised of blood vessels, which include arteries, veins, and capillaries. Arteries carry blood away from the heart, typically oxygenated blood, while veins carry blood back towards the heart, generally deoxygenated blood. Capillaries are tiny, thin-walled vessels that form a network within tissues, facilitating the exchange of gases, nutrients, and waste products between the blood and the cells. The continuous movement of blood through these vessels is vital for maintaining bodily functions and overall health.
