THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Renal pyramids are kidney tissues that are shaped like cones. The medulla is the inner layer that contains the pyramids and columns.

Detailed explanation-2: -The renal medulla also consists of the renal columns, which are the spaces between the renal pyramids, and the renal papillae. The renal papillae refer to the tips of the renal pyramids, which collect the remainder of the filtrate that consists of waste and solutions.

Detailed explanation-3: -The medulla consists of multiple pyramidal tissue masses, called the renal pyramids. In between the pyramids are spaces called renal columns through which the blood vessels pass. The tips of the pyramids, called renal papillae, point toward the renal pelvis. There are, on average, eight renal pyramids in each kidney.
