The renal medulla (Latin: medulla renis 'marrow of the kidney') 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.
The venous drainage of the kidney large mirrors its arterial supply, except that there are no segmental veins. [4] The stellate veins arise from the capillaries, then drain successively through interlobular veins and interlobar veins until these converge from across the kidney to form the renal vein for that kidney.
The renal cortex is the outer portion of the kidney between the renal capsule and the renal medulla. [1] In the adult, it forms a continuous smooth outer zone with a number of projections (cortical columns) that extend down between the pyramids.
The nephron is the functional unit of the kidney. [3] This means that each separate nephron is where the main work of the kidney is performed. A nephron is made of two parts: a renal corpuscle, which is the initial filtering component, and; a renal tubule that processes and carries away the filtered fluid. [4]: 1024
In anatomy, a medullary ray (Ferrein's pyramid) is the middle part of a cortical lobule (or renal lobule). Each consists of a group of nephrons in the renal cortex . [ 1 ] Their name is potentially misleading, as "medullary" refers to their destination, not their location.

Like the bony pelvis, the renal pelvis (/ ˈ r iː n əl ˈ p ɛ l v ɪ s /) gets its English name via Neo-Latin from the older Latin word pelvis, "basin", as in "wash basin". [4] In both cases the name reflects the shape of the structure, and in the case of the renal pelvis, it also reflects the function.
