THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The mature renal medulla, the inner part of the kidney, consists of the medullary collecting ducts, loops of Henle, vasa recta and the interstitium. The unique spatial arrangement of these components is essential for the regulation of urine concentration and other specialized kidney functions.

Detailed explanation-2: -The Kidneys Are Composed of Three Main Sections Each kidney consists of an outer renal cortex, an inner renal medulla, and a renal pelvis. Blood is filtered in the renal cortex. The renal medulla contains the renal pyramids, where urine formation takes place. Urine passes from the renal pyramids into the renal pelvis.

Detailed explanation-3: -Internally, the kidney has three regions-an outer cortex, a medulla in the middle, and the renal pelvis in the region called the hilum of the kidney.
