what is a heart and the kidney?

Answers

Answered by merlina

The kidneys are two organs, each about as big as a fist and shaped like a kidney bean. As the heart pumps blood throughout the body, kidneys clean it, remove waste, help maintain blood pressure, and ensure the blood has the right amounts of certain nutrients and minerals. Kidney disease means the kidneys are damaged.

heart collects the blood from superior venacava and inferior venacava veins. and sends to right ventricle by pulmanary vein to the lungs. by lungs it flows to the right ventricle. from right ventricle to it flows through out our body.by pulmanary arota. so heart pumps the blood.
kidneys are the excretary organs. kidneys contain nephron which filters the blood. at last results in formation of urine.....
hope it will help u
