THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The main job of the kidneys is to remove waste from the blood and return the cleaned blood back to the body.

Detailed explanation-2: -Blood enters the kidneys through an artery from the heart. Blood is cleaned by passing through millions of tiny blood filters. Waste material passes through the ureter and is stored in the bladder as urine. Newly cleaned blood returns to the bloodstream by way of veins.

Detailed explanation-3: -The kidneys act as very efficient filters for ridding the body of waste and toxic substances, and returning vitamins, amino acids, glucose, hormones and other vital substances into the bloodstream. The kidneys receive a high blood flow and this is filtered by very specialised blood vessels.

Detailed explanation-4: -Once the urine is formed, it passes through the nephrons and down the renal tubules of the kidney. Urine collects in the calyces and flows into the renal pelvis and then flows into the ureter. From here it flows down into the bladder.
