Cerebral blood flow (CBF) is the blood supply to the brain in a given period, crucial for delivering oxygen and nutrients while removing metabolic waste. Proper regulation of CBF is essential for maintaining neural function and preventing conditions like stroke and brain ischemia.

Cerebral Blood Flow

Cerebral blood flow

The brain receives its blood supply from two main pairs of arteries: the internal carotid arteries and the vertebral arteries, which together form the Circle of Willis, ensuring a continuous and redundant supply of oxygenated blood. Disruptions in this blood flow, such as from a stroke or aneurysm, can lead to significant neurological deficits or even death, highlighting the critical importance of maintaining cerebral circulation.

blood supply to the brain

Oxygen delivery refers to the process by which oxygen is transported from the lungs to the tissues via the bloodstream, which is crucial for cellular metabolism and energy production. It is influenced by factors such as cardiac output, hemoglobin concentration, and the oxygen saturation of hemoglobin.

Oxygen Delivery

Nutrient delivery refers to the process of transporting essential nutrients from the external environment to cells within an organism, ensuring proper cellular function and overall health. This process involves complex interactions between digestive, circulatory, and cellular systems to efficiently distribute and utilize nutrients throughout the body.

Neural function refers to the complex processes by which neurons communicate, process information, and coordinate actions within the nervous system. It is fundamental to understanding how the brain enables perception, thought, emotion, and behavior through intricate networks of synaptic connections and neurotransmitter interactions.

Stroke prevention focuses on reducing risk factors such as hypertension, smoking, and high cholesterol through lifestyle changes and medication. Early intervention and regular health screenings are crucial for identifying and managing conditions that increase stroke risk.

Stroke Prevention

Brain ischemia occurs when there is insufficient blood flow to the brain to meet metabolic demand, leading to limited oxygen and nutrient supply and potentially resulting in brain damage or stroke. Prompt diagnosis and intervention are critical to restoring blood flow and minimizing neurological damage.
