aivoverenkierrot

Aivoverenkierrot, also known as cerebral circulation, refers to the blood supply to the brain. This intricate network of arteries and veins ensures that the brain receives a continuous and adequate flow of oxygen and nutrients, essential for its proper functioning. The brain is a highly metabolically active organ, demanding a significant portion of the body's total blood supply.

The primary arteries supplying blood to the brain are the internal carotid arteries and the vertebral arteries. These vessels branch out into smaller arteries, forming a complex network that reaches every part of the brain. The Circle of Willis, a crucial arterial anastomosis located at the base of the brain, plays a vital role in ensuring continuous blood flow even if one of the major arteries is partially or completely blocked.

Venous drainage from the brain occurs through a system of dural venous sinuses, which eventually merge to form the internal jugular veins. These veins carry deoxygenated blood away from the brain back to the heart. Disruptions to aivoverenkierrot, such as blockages or hemorrhages, can lead to serious neurological conditions, including stroke. Maintaining healthy blood pressure, cholesterol levels, and avoiding smoking are important factors in preserving optimal cerebral circulation.
