Kidneys filter the blood in the body by removing the toxins and disposing them through urine. This function helps the body to clear any build up of waste within the body, and helps to keep the body from poisoning itself.
Oxygenated blood enters the kidneys through the renal arteries. Blockage of these arteries can affect kidney function as well as blod pressure.
Kidneys receive blood from systemic circulation via the RENAL ARTERIES, the blood flows through them and re-enters systemic circulation via the RENAL VEINS
The renal artery delivers blood to the kidneys.
The Arteries.
Renal veins take blood away from the kidneys and renal arteries bring blood to the kidneys
They drain unfilterd blood from the body into the kidneys
to the heart to be pumped out to the body through arteries
to carry blood to and from the kidneys.
Renal artery or renal columns--- the arterial supply of each kidney is the renal artery. As the renal artery approaches the hilum, it divides into segmental arteries, each of which gives off several branchel called interlobar arteries, which travel through the renal columns to reach the cortex.
Blood leaves the heart through arteries, and returns through veins.
The arteries carry highly oxygenated blood. The veins carry deoxgenated blood and cellular wastes back to the kidneys to process waste and to the lungs to exchange CO2 for more O2.
