Explanation / Answer

A) Renal medulla is the base of the structure borders the renal cortex. Renal medulla is made up of 10- 18 conical subdivisions. The pyramids appear striped because these are formed by the parallel segments of the nephrons and collecting ducts.

B) The proximal and distal convoluted tubules are located in the CORTEX region.

C) The main organs of the urinary system are the kidneys. These are involved in the formation of the urine. Ureters are the thin tubes that take urine to the bladder. Bladder is the sac that holds urine. Urethra is the tube that carries urine from bladder to outside of the body.

D) Papillary duct drains into the renal pyramid at the rennal papillae.

E) The inward extensions of the renal cortex are called as Renal columns.

F) Major calyces are formed by the combination of 1 or 2 minor calyces. The major calyces drain urine directly through the renal pelvis into the ureter.

G) Renal cortex is the apex of the renal pyramid.

H) Several minor calyces merge to form the major calyces.
