GENERAL HISTOLOGY

Detailed explanation-1: -The renal medulla is the innermost part of the kidney. The renal medulla is split up into a number of sections, known as the renal pyramids. Blood enters into the kidney via the renal artery, which then splits up to form the segmental arteries which then branch to form interlobar arteries.

Detailed explanation-2: -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-3: -The renal or kidney medulla is the inner part of the kidney. The medulla helps regulate the concentration of urine by filtering out water, salts, and acid.

Detailed explanation-4: -The innermost portion of the kidney is a funnel-shaped cavity called the renal pelvis. It contains the renal artery and renal vein as well as the ureter.
