00:01 So in this question we are given various parts of the kidney and we need to match the parts with their appropriate functions.

00:10 So firstly we are given a, the calluses of the kidney.

00:16 Now calluses are basically the extensions of renal pelvis.

00:21 So they are the extension of renal pelvis which go up to the renal papilla.

00:34 So they go up to the renal papilla and they contain the urine.

00:40 So these are basically extensions of renal pelvis.

00:44 Then moving on we have the hilum of kidney.

00:47 Now hilum is the area from which all the blood vessels and the nerves they enter the kidney.

00:55 So the area from which all the blood vessels and nerves enter the kidney it is called as the hilum.

01:05 So it is basically a medial depression, medial depression like area in the middle of the kidney for the blood vessels and ureter to enter.

01:19 For blood vessels and ureter to enter the kidney.

01:30 So for the entry of ureter and blood vessels, there is a hilum which is a depression like structure on the middle of kidney.

01:41 Then we have nephron.

01:43 Nephron is the basic filtering unit of kidney.

01:46 So it is the microscopic functional subunit of kidney.

01:51 Nephrons are microscopic.

01:52 They are very small and they perform the filtration of blood.

01:56 So they are the functional unit.

02:00 The kidney next we have the renal column renal column now the renal column is basically a cortical tissue extension the cortex when it extends towards the medulla so this is basically cortical tissue extension and it is present between the renal pyramid so it is present between renal pyramids so these renal pyramids they are present in the medulla and between these pyramids there is a cortical tissue which is called as the renal column now moving on we have the renal cortex so renal cortex is basically the outer portion of the kidney so this is the superficial region around the renal medulla superficial superficial means outer region and it is present around the medulla.

03:05 So around renal medulla.

03:08 A medulla is present in the center or middle.

03:13 Then we have the renal papilla.

03:16 So renal papilla.

03:20 This is basically a projection which has tiny openings to connect to the collecting duct...
