20%
The brain consumes 40% of the oxygen in your blood.
A Neanderthal brain was around 10-15% larger than a modern human brain, on average.
If you mean "How much percentage of water does a human brain have?", the answer is about 77-78%.
5.72 million red blood cells per microliter (mcL) of blood for men and 5.03 million per mcL for women. In healthy men, 41 percent to 50 percent of blood is red blood cells. In healthy women, 35 percent to 46 percent is red blood cells
The cerebellum makes up to what percent of the brain

they supply oxygen to red blood cells, which in turn supplies oxygen to your muscles and brain...which are required to live.

The average size of a donkey's brain is comparable to a human. The donkey's brain is between 50 and 75 percent of the size of the human brain.
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.
100%. 5 pints +/-
For an average adult human, 5 percent of the blood supply enters or leaves the heart with each heartbeat.
The blood cells, stomach, and brain do.
The blood reaches the brain because of heart pumping. the heart is capable of supplying blood in all "1G" conditions to all parts depending upon requirement.
The brain uses about 20% of the body's oxygen supply, despite making up only about 2% of its weight. This high oxygen demand is necessary to support the brain's energy-intensive functions, such as thinking and processing information.
