Vessaflæði

Vessaflæði, also known as blood flow, refers to the movement of blood through the circulatory system. It is a critical process that ensures the delivery of oxygen and nutrients to tissues and the removal of waste products such as carbon dioxide. Blood flow is regulated by the heart, which pumps blood through a network of arteries, capillaries, and veins.

The heart's pumping action creates pressure that propels blood through the arteries to the capillaries, where oxygen and nutrients are exchanged with the surrounding tissues. This process is facilitated by the heart's four chambers: the right atrium, right ventricle, left atrium, and left ventricle. The right side of the heart pumps deoxygenated blood to the lungs, while the left side pumps oxygenated blood to the rest of the body.

Blood flow is influenced by various factors, including heart rate, blood pressure, and the diameter of blood vessels. Conditions such as hypertension, atherosclerosis, and anemia can affect blood flow, leading to potential health issues. Maintaining healthy blood flow is essential for overall cardiovascular health and the proper functioning of the body's systems.
