Explanation / Answer

Renal calyces are structures in the renal pelvis that collect urine before passing it to the urinary tract. There are two types of urinary calyx present: major (2-3) and minor calyces (8-14). Urine is processed by the renal cortex and sent to the renal medulla. The renal papilla strains the urine and is collected in the cavities of the renal calyces, first in the minor calyces, which join the major calyces. Urine collects in the renal pelvis, then the ureter and finally the urinary bladder.

Hilium of Kidney, a depression or pit, is the entrance to the renal sinus. It admits renal veins, arteries, nerves, ureter, and lymphatic vessels. Blood vessels and ureter enter a kidney chamber through the medial depression or Hilium.

Nephron is the microscopic functional subunit of the Kidney. They can be superficial, midcortical or juxtamedullary based on glomerulus location. It has two components: the glomerulus, the site of initial blood filtration and the renal tubule composed of proximal convoluted tubule, loop of Henle, distal convoluted tubule and the collecting duct. There are approximately one million nephrons in each kidney.

Renal column are extensions of renal cortex located in medulla between the renal pyramids. It functions to anchor the renal cortex. It is also the site of passage of interlobar arteries from renal sinus to the cortex. They also have urine-producing nephrons.

Renal cortex is the outer layer of kidney, a superficial region around the medulla. It contains the large numbers of the glomeruli in the renal corpuscles. It also has nephrons, which produce urine.

Renal papilla: It is the apex of the renal pyramid with tiny openings projecting into the minor calyx. It is white fatty material of the kidneys and covered by stratified cuboidal epithelium.

Renal pelvis: It is the largest collecting chamber of urine from the major calyces. It is located in renal hilius and surrounded by renal sinus. It is superficial funnel shaped sac at the end of the ureter and is dilated origin of the ureter.

Renal pyramid is the triangular/cone-shaped mass of renal tubule within the renal medulla. Each pyramid tip opens into the minor calyx. Pyramids are purple brown dark area with tubules running in parallel.

Renal Sinus is the potential hollow space on the medial side of the kidney. It opens at the renal hilius. Renal sinus contains blood vessels, renal pelvis, renal calyces, nerves, and adipose tissues.
