Kerfisblóðrásarinnar

Kerfisblóðrásarinnar, also known as the systemic circulation, is a vital component of the cardiovascular system responsible for transporting oxygen and nutrients to tissues and removing waste products such as carbon dioxide. It begins with the left ventricle of the heart, which pumps oxygenated blood into the aorta, the largest artery in the body. From the aorta, blood is distributed to various organs and tissues through a network of arteries and arterioles.

The systemic circulation can be further divided into two main pathways: the pulmonary circulation and the coronary circulation. The pulmonary circulation supplies oxygenated blood to the lungs, where gas exchange occurs. The coronary circulation provides oxygen and nutrients to the heart muscle itself.

The systemic circulation plays a crucial role in maintaining homeostasis by ensuring that all cells in the body receive the necessary oxygen and nutrients for proper functioning. It also helps in the regulation of body temperature, pH balance, and fluid balance. Any disruption in the systemic circulation, such as in conditions like hypertension or atherosclerosis, can lead to serious health issues.
