If a person’s brain is not receiving enough blood, that means that the brain will start to send the wrong signals to the wrong part of the body, like making your stomach think it is hungry when actually you are not.

The brain produces wastes that red blood cells need to take away from the brain. If the blood does not do this, the brain can get poisoned.

If a person’s brain is not receiving enough blood, that means their brain starts to “suffocate” because it is not getting enough oxygen. When the brain doesn’t receive enough oxygen, the result is that the person will have a stroke.

Detailed explanation-1: -Cerebral hypoxia is a neurological condition that happens when the brain doesn’t get enough oxygen, even though there is good blood flow. It is a medical emergency that can happen from many events where oxygen to the brain may be cut off, such as from drowning, choking, suffocation, cardiac arrest, or head injury.
Detailed explanation-2: -The brain lacks fuel stores and requires a continuous supply of glucose and oxygen. Therefore, continuous cerebral blood flow (CBF), cerebral oxygen tension and delivery, and normal mitochondrial function are of vital importance for the maintenance of brain function and tissue viability.
Detailed explanation-3: -Accidents, heart attacks and strokes can deprive the brain of oxygen, leading to cerebral hypoxia. Cerebral hypoxia is a medical emergency. It can cause permanent brain injury. If the brain goes too long without oxygen, brain death and coma can occur.
Detailed explanation-4: -Permanent brain damage or death can occur within minutes if a person’s blood flow stops.
