red blood cells
There is a redundant blood supply to the brain to ensure uninterrupted oxygen and nutrient delivery, as the brain is highly sensitive to any disruption in blood flow. The redundancy comes from the two main arteries that supply the brain, the internal carotid arteries and the vertebral arteries, which can compensate for each other if one becomes compromised. This redundancy helps to minimize the risk of brain damage due to reduced blood flow.
Human blood is primarily made up of plasma, which is a liquid component that carries blood cells and nutrients throughout the body. The second component is blood cells, which include red blood cells, white blood cells, and platelets.

The brain needs so much blood because it needs a constant supply of it to keep up with the neurons metabolic demands. 20 percent of the blood that comes from the heart is pumped directly to the brain.
The body's entire blood supply is circulated through the cardiovascular system approximately every minute. This process ensures that oxygen and nutrients are delivered to all tissues and organs, while waste products are removed efficiently.
The aorta is the largest artery in your body and is connected directly to the heart and it also carries the blood to the rest of your body and disperses the blood to the branches of other arteries extended off the aorta.

The human body can produce about 2 million red blood cells per second, equating to about 1.5 million red blood cells per drop of blood. However, the production of a pint of blood (which contains over 200 trillion red blood cells) would take several days to weeks as the body constantly replenishes its blood supply.
The blood vessels of the body are functionally divided into two distinctive circuits: pulmonary circuit and systemic circuit. The pump for the pulmonary circuit, which circulates blood through the lungs, is the right ventricle. The left ventricle is the pump for the systemic circuit, which provides the blood supply for the tissue cells of the body.

Yes. Blood is normally donated a pint at a time. The body replaces it within 2 weeks.
