The kidneys are a pair of bean-shaped organs on either side of the spine, below the ribs and behind the belly. Each kidney is about 4 or 5 inches long, roughly the size of a large fist. The main function of the kidneys is to filter the blood and form urine. It is divided into two main parts- outer cortex and an inner medulla.
1. Shell around the renal medulla- e. Renal cortex
renal cortex is the outer portion of the kidney
2. branches of renal pelvis to renal papillae - a. Calyces
renal calyces are chambers of the kidney through which urine passes.
3. conical mass of tissue within renal medulla- h. Renal pyramid
Renal pyramids consist mainly of tubules that transport urine from the outer, part of the kidney, where urine is produced, to the calyces, in which urine collects before it passes through the ureter to the bladder.
4. projection with tiny openings into a minor calyx- f. Renal papilla
the renal papilla is the place where the renal pyramids in the medulla empty urine into the minor calyx in the kidney.
5. hollow chamber within the kidney - i. Renal sinus
renal sinus is a cavity within the kidney which is occupied by the renal pelvis, renal calyces and blood vessels.
6. microscopic functional unit of the kidney - c. nephron
A nephron is a tubule which consists of many parts including glomerulus which filters the fluid and helps in the urine formation.
7. cortical tissue between renal pyramids-d. Renal column
Renal column is a medullary extension of the renal cortex in between the renal pyramids.
8. superior funnel-shaped end of ureter inside the renal sinus-g. Renal pelvis
the renal pelvis is the point where the two or three major calyces join together.
9. medial depression for blood vessels and ureter to enter kidney chamber- b. hilum
Renal hilum is deep vertical slit situated in its medial border.
