Question 1

What is the functional unit of the kidney?

Answer 1

Nephron

Question 2

Afferent arterioles in the kidney take blood to the?

Answer 2

Glomerulus

Question 3

Main job of the glomerulus?

Answer 3

Filter the blood and provide raw materials for urine production

Question 4

Efferent arterioles take blood from glomerulus to ____ capillaries

Answer 4

Peritubular

Question 5

Peritubular capillaries bring blood from the glomerulus to?

Answer 5

Proximal convoluted tubule

Question 6

Main job of proximal convoluted tubule?

Answer 6

Reabsorb (back to blood) anything that was filtered that we need and secrete (into urine) anything that did not get filtered that we do not want

Question 7

From the PCT, vasa recta provide blood to the?

Answer 7

Loop of Henle

Question 8

Main job of Loop of Henle?

Answer 8

Concentration

Question 9

From the loop of henle, peritubular capillaries bring blood to the?

Answer 9

Distal Convoluted Tubule

Question 10

Main job of the Distal convoluted tubule?

Answer 10

Fine tuning of electrolytes and water

Question 11

The distal convoluted tubule is under what control?

Answer 11

Hormonal and neural (ANS)

Question 12

Primary innervation to the kidney?

Answer 12

SYMPATHETIC

Question 13

What type of sympathetic receptors are on kidney arterioles?

Answer 13

Alpha 1 adrenergic

Question 14

Alpha 1 adrenergic receptors on kidney arterioles do what when stimulated?

Answer 14

Vasoconstriction = decrease blood flow to kidney and decrease urine production

Question 15

What type of sympathetic receptors are on the kidney juxtaglomerular apparatus?

Answer 15

Beta 1 adrenergic

Question 16

Beta 1 adrenergic receptors on kidney juxtaglomerular apparatus do what when stimulated?

Answer 16

Increase renin release
– increase sodium and water reabsorption
= increase blood volume to maintain BP

Question 17

What region of the brain primarily controls the ANS response?

Answer 17

Hypothalamus

Question 18

For sympathetics, pre-ganglionic fibers synapse where most of the time?

Answer 18

Sympathetic chain

Question 19

Pre-ganglionic sympathetic fibers release?

Answer 19

Ach - acetylcholine

Question 20

Pre-ganglionic sympathetic fibers release Ach to what receptors?

Answer 20

Nicotinic (NAchR) on post-ganglionic

Question 21

Post-ganglionic sympathetic fibers release?

Answer 21

NE - norepinephrine

Question 22

_____ determines what type of adrenergic receptor NE will bind to from a post-ganglionic sympathetic fiber release

Answer 22

Target tissue

Question 23

2 actions of sympathetic innervation on the kidney?

Answer 23

1. Vasoconstriction - decrease blood flow and urine production
2. Renin release - increase Na+ and H20 reabsorption to increase blood volume

Question 24

What 2 things in the kidney do sympathetics act on?

Answer 24

Arterioles

Juxtaglomerular apparatus

Question 25

What 2 receptors in the kidney do sympathetics act on?

Answer 25

Alpha 1 adrenergic

Beta 1 adrenergic

Question 26

Alpha 1 adrenergic receptors are on ___ in the kidney

Answer 26

Arterioles

Question 27

Beta 1 adrenergic receptors are on _____ in the kidney

Answer 27

Juxtaglomerular apparatus
