Question

4. Where is the kidney located in the body? Why is it important to clean blood?

Answer 1

KIDNEY remove wastes, control the body's fluid balance, and keep the right levels of electrolytes. All of the blood in your body passes through them several times a day.
They reside against the back muscles in the upper abdominal cavity. They sit opposite each other on either side of the spine. The right kidney sits a little bit lower than the left to accommodate the liver.

Answer 2

heya!

The kidneys are bean-shaped organs (about 11 cm x 7 cm x 3 cm) that are located against the back muscles in the upper abdominal area. They sit opposite each other on both the left and right side of the body; the right kidney, however, sits a little lower than the left to accommodate the size of the liver.

The kidneys do a lot, but their most important job is to take waste out of the blood and make urine.
The main job of the kidneys is to filter the waste out of the blood. How does the waste get in your blood? Well, your blood delivers nutrients to your body. Chemical reactions occur in the cells of your body to break down the nutrients. Some of the waste is the result of these chemical reactions. Some is just stuff your body doesn't need because it already has enough. The waste has to go somewhere; this is where the kidneys come in.
