Intro Renal/ Glomerular Filtration

Question 1

The urinary System

Answer 1

• Filter your blood to make pee.
• Regulates water & ion & acid- base balance
• excretes metabolic wastes., foreign chemical
• Hormone synthesis

Question 2

Functional unit of the kidney

Answer 2

Nephron

Question 3

Each contains renal corpuscle and renal tube

Answer 3

Nephron

Question 4

20% of blood in glomerular capillaries is filtered into

Answer 4

Bowmans Space

Question 5

What gets filtered and ends up in Bowmans space?

Answer 5

Electrolytes, water, vitamins

Question 6

Medications for Kidney stones

Answer 6

water, alpha blocker relax smooth muscles in ureter

Question 7

The kidneys two sets of capillaries are

Answer 7

Peritubular and glomerular

Question 8

Reabsorbed from the renal tubule, where is it traveling

Answer 8

into the blood

Question 9

Glomerular filtration

Answer 9

blood (glomerular capillaries ) to Bowman’s space.

Question 10

Tubular secretion

Answer 10

peritubular capillary blood back to the renal tubule

Question 11

Filtration is selective

Answer 11

only for size, not selective for everything else

Question 12

Blood Pressure in glomerular capillaries (PGC)

Answer 12

favors filtration ~60mmHg

Question 13

Hydrostatic pressure in Bowmans Space (PBS)

Answer 13

Goes against filtration ~15 mmHg

Question 14

Osmotic force due to proteins in plasma

Answer 14

goes against filtration ~29 mmHg

Question 15

Factors that increase Glomerular Filtration Rate (GFR)

Answer 15

Dilate afferent arteriole
Constrict efferent arteriole
Coffee

Question 16

Factors that decrease GFR

Answer 16

Constrict afferent arteriole

Dilate efferent arteriole

Question 17

Transport maximum

Answer 17

even though theres more glucose in blood, kidney cant reabsorb saturated transporters
