Final answer:

The medullary pyramid, also known as the renal pyramid, is a cone-shaped tissue found in the medulla of the kidney. It contains the collecting ducts and loops of Henle and plays a crucial role in the concentration and excretion of urine. The medullary pyramid, along with the renal papillae, forms the lobes of the kidney, allowing for its excretory and osmoregulatory functions.

Step-by-step explanation:

The medullary pyramid, also known as the renal pyramid, is a cone-shaped tissue found in the medulla of the kidney. It contains the collecting ducts and loops of Henle of the juxtamedullary nephrons. The medullary pyramid plays a crucial role in the concentration and excretion of urine.

Within the medullary pyramid, there are structures called renal papillae where the collecting ducts empty urine into the minor calyces, which eventually leads to the renal pelvis. The medullary pyramid, along with the adjoining cortical region, forms the lobes of the kidney. The lobes and pyramids make up the internal anatomy of the kidney, allowing for its excretory and osmoregulatory functions.
