HUMAN NUTRITION

Detailed explanation-1: -A stroke, sometimes called a brain attack, occurs when something blocks blood supply to part of the brain or when a blood vessel in the brain bursts. In either case, parts of the brain become damaged or die. A stroke can cause lasting brain damage, long-term disability, or even death.

Detailed explanation-2: -A stroke, also known as transient ischemic attack or cerebrovascular accident, happens when blood flow to the brain is blocked. This prevents the brain from getting oxygen and nutrients from the blood. Without oxygen and nutrients, brain cells begin to die within minutes.

Detailed explanation-3: -Brain cells do not get the nutrients they need if blood flow to the brain is reduced or stopped. This can prevent them from working correctly. Blood flow that stops for long enough can damage or kill brain cells. This can cause a stroke.

Detailed explanation-4: -An ischemic stroke occurs when a blood vessel that supplies the brain becomes blocked or “clogged” and impairs blood flow to part of the brain. The brain cells and tissues begin to die within minutes from lack of oxygen and nutrients.
