The cerebrovascular system refers to the network of blood vessels that supply blood to the brain. This system includes arteries, veins, and capillaries that ensure the delivery of oxygen and nutrients while removing waste products. Proper functioning of the cerebrovascular system is essential for maintaining brain health and overall cognitive function. Disruptions in the cerebrovascular system can lead to serious conditions such as stroke or transient ischemic attack (TIA). These events occur when blood flow to a part of the brain is reduced or blocked, resulting in potential brain damage. Understanding this system is crucial for preventing and treating cerebrovascular diseases.
