What is renal parenchyma? The renal parenchyma can be divided into cortex and medulla, and the cortex is composed of glomeruli and curved tubules. The medulla is composed of 15 to 20 kidney vertebral bodies, and the tip of the kidney cone protrudes into the renal nipple, which is the opening of the nipple tube and the collecting tube. The renal pelvis is funnel-shaped, surrounding 1~3 kidney nipples, and every 2~3 kidneys are combined into one kidney sputum. Generally, the kidney has 3 large…Continue
