Why does the blood leaving most organs in the brain have less oxygen than when it entered the brain?
The brain is generally considered one organ, and yes blood delivers oxygen to the brain, so when the blood leaves the brain, it is oxygen depleted. This oxygen fuels the brain through respiration, which gives it the energy to keep you alive and constantly keep your bodily functions in line.
There is a blood brain barrier though, so blood never actually enters the brain and oxygen diffuses over this barrier.

What organs supply blood with oxygen in mammals?
the lungs supply the blood with oxygen, within the lungs there are alveoli which have a very thin membrane which allows oxygen to pass into the capillaries that run into the lungs hope i helped
How is blood leaving the left side of the heart different from the blood entering the right side?

What organ system delivers oxygen and nutrients to muscles and organs around the body?

Is the blood leaving the left ventricle oxygenate or deoxygenated?
deoxygenated
Oxygen passes from the blood into organs through the walls of?
Oxygen passes from the blood into organs through the wall of capillaries.
How does blood entering the lungs differ from blood leaving the lungs?
The blood leaving the lungs is loaded with oxygen, while blood entering the lungs is about to get oxygen from the respiratory system.
Where do oxygen rich blood go after leaving the lungs?
Oxygen-rich blood leaves the lungs through the pulmonary veins and is transported to the left side of the heart. From there, it is pumped out to the rest of the body through the aorta and the systemic circulation to provide oxygen to tissues and organs.
What passes through the body organs?
Blood and oxygen.
What function of the blood?
supply oxygen to all organs
How does oxygen in the air get to all the important organs?
Oxygen from the air is inhaled into the lungs, where it diffuses into the bloodstream. The heart then pumps this oxygen-rich blood to all the important organs through a network of blood vessels. The organs extract the oxygen they need for cellular function from the blood.
Is the blood arriving at the alveoli from the heart rich in oxygen?
No, but the blood leaving is.
What organs that fill blood with oxygen is?
The lungs are the primary organs that fill blood with oxygen. Oxygen from the air is inhaled into the lungs, where it moves into the bloodstream through tiny blood vessels called capillaries surrounding the lungs' air sacs.
What does blood carry to the other organs in the body?
oxygen and nutrients
What is a function of humam blood?
