GENERAL HISTOLOGY

Detailed explanation-1: -The right kidney usually is slightly lower than the left because the liver displaces it downward. The kidneys, protected by the lower ribs, lie in shallow depressions against the posterior abdominal wall and behind the parietal peritoneum. This means they are retroperitoneal.

Detailed explanation-2: -The left kidney sits a bit higher in the body because of the size of the liver, which is also on the right side. Muscles in your back and your ribcage protect your kidneys from both the front and the back sides of your body. There is also fat tissue, called perirenal fat, that surrounds the kidneys for protection.

Detailed explanation-3: -The urine formed is drained into the ureter, a tube that leads downwards from the collecting part of the kidney, the renal pelvis, into the urine storage and release organ, the urinary bladder.
