Renal Structure And Function

Front 1

Basic unit of kidney

Back 1

Uriniferous tubule

Front 2

2 distinct kidney sections with differing embryologic origins

Back 2

1. Collecting tubule
2. Nephron

Front 3

Tuft of blood vessels in the nephron

Back 3

Glomerulus

Front 4

Epithelium in Bowman's capsule

Back 4

Squamous

Front 5

Interlocking epithelium of the visceral epithelium forming part of blood urine barrier

Back 5

Podocytes

Front 6

3 components of blood-urine barrier

Back 6

1. Walls of capillaries
2. Basement membranes
3. Slit pore membrane

Front 7

Proximal convoluted tubule has what epithelium?

Back 7

short simple columnar w/ villi and apical canaliculi

Front 8

Distal convoluted tubule has what epithelium?

Back 8

short cuboidal w/O villi

Front 9

Collecting tubule has what epithelium?

Back 9

Cuboidal at first, toward the renal pyramid it changes to columnar

Front 10

3 structures in the renal cortex.

Back 10

1. Glomerulus
2. Prox Conv Tub
3. Dist Conv Tub.

Front 11

The three pressures involved in fluid movement in the kidney.

Back 11

1. Cardiac pressure-- 70 mm hg
2. Colloid pressure of blood--32 mm hg
3. Bowman's capsule pressure-- 20 mm hg

Front 12

3 functions of mesangial cells

Back 12

1. Form architecture of glomerulus
2. Phagocytize large proteins
3. Control blood flow thru glomerular capillary via contractility

Front 13

The path of the blood thru the kidney.

Back 13

1. Renal artery
2. Interlobular arteries
3. Intralobular arteries
4. Afferent arterioles
5. Glomerulus
6. Efferent arterioles
7. Vasa recta capillaries

Front 14

How does the area surrounding the ascending thin limb draw out so much water?

Back 14

Cells pump Na into interstitial space, creating an osmotic gradient favoring water absorption. HEAVY ATP usage.

Front 15

7/8 of water resorption happens where?

Back 15

Proximal convoluted tubule

Front 16

Ammonia, urea, and H+ ions are added where?

Back 16

Distal convoluted tubule

Front 17

ADH acts mainly where?

Back 17

Collecting tubules

Front 18

Deficiency in ADH causes what disease?

Back 18

Diabetes insipidus

Front 19

This hormone affects sodium uptake

Back 19

Aldosterone

Front 20

The antagonist of ADH is called? Produced where?

Back 20

atrial natriuretic hormone, atrium of heart
