35
Q

Definition of medulla

A

All ends up as you’re in and extreted out of the body

36
Q

Juxtamedullary nephrons

A

Near the cortical medullary border
-Extends deep into medulla

37
Q

Cortical nephrons

A

Near the cortex, not in the medulla

38
Q

Microscopic processes

A

39
Q

What is the deepest layer in the renal corpuscle?

A

Glomerulus

40
Q

Tubular secretion

A

Not in renal corpuscle
-Occurs in between peritubular, capillary and renal tubular structure(4)

41
Q

How does the kidney detect body fluids?

A

Through macula, densa cells

42
Q

⬆️ osmolality

A

⬆️ solute ⬇️ solvent

43
Q

⬇️ osmolality

A

⬇️ solute ⬆️ solvent

44
Q

⬆️ osmolality does…

A

Decreases blood volume/pressure
-Also produces renin

Q

What cells produce renin?

A

JG

47
Q

What detect osmolality
