the blood passes through your heart
All the blood passes through
Not all blood passes through the kidneys each time, in the way all blood passes through the lungs. About 20% of the blood leaving the heart passes through the kidneys, meaning that all of a persons blood should pass through the kidneys about 12 times every hour.
they have a single loop meaning the blood passes through the heart only once to go to everywhere in the body
The blood enters the capillaries in single file ( capillaries have very small diameter so blood flow through them as in single line) there by diffusion the food passes towards the cell and waste from the blood enter the blood stream
The blood passes through tiny capillaries that lie in close proximity to the alveoli in the lungs. This is where the gas exchange takes place.
This occurs in the small intestine by deffusion into the blood stream.
