Q

What makes up 85% of nephrons?

A

cortical nephrons

21
Q

What makes up the majority of nephrons in the cortex?

A

cortical nephrons

22
Q

What makes up 15% of nephrons?

A

juxtamedullary

23
Q

What do the juxtamedullary nephrons dip into?

A

medulla

24
Q

What is the function of the juxtamedullary nephron?

A

concentrates urine

25
Q

What capillaries follow convoluted tubules?

A

peritubular capillaries

26
Q

What type of capillary is found in the cortex?

A

peritubular

27
Q

What type of capillary is found primarily in the medulla?

A

vasa recta

28
Q

What does the vasa recta capillary follow?

A

nephron loop of juxtamedullary nephrons

29
Q

What are the components of the filtration membrane?

A

fenestrated epithelium, basal lamina, and podocyte

30
Q

What is the purpose of the fenestrated epithelium?

A

allows solutes to pass, but not larger cells or large plasma proteins

31
Q

What is the purpose of the basal lamina in the filtration membrane?

A

repels negatively charged solutes/molecules because it is negatively charged

32
Q

What is the basal lamina of the filtration membrane made out of?

A

type III collagen

33
Q

What is the purpose of the podocyte in the filtration membrane?

A

foot processes create slit membranes that prevent filtration of medium-sized proteins

34
Q

What regulates what is released from blood using the filtration membrane?

A

glomerular filtration

35
Q

What removes substance from the blood and adds back to the tubules?

A

tubular secretion

36
Q

Does tubular secretion occur along the length of the tubule?

A

yes

37
Q

What removes substances from the tubules and adds back to the blood?

A

tubular reabsorbtion

38
Q

Does tubular reabsorbtion occur along the length of the tubule?

A

yes

39
Q

What is the function of the proximal convoluted tubule?

A

reabsorbtion

40
Q

What is the difference in the proximal convoluted tubule epithelium and distal convoluted tubule epithelium?

A

simple columnar in proximal; simple cuboidal in distal

41
Q

What is the function of the distal convoluted tubule

A

regulates K, Na, and NaCl

42
Q

What is the function of the juxtaglomerular apparatus?

A

maintains blood pressure and to act as a quality control mechanisim to endure proper glomerular flow rate and efficent sodium reabsorption

43
Q

What is the path of urine once it leaves the collecting duct?

A

collecting duct–>Ureter–>Bladder

44
Q

What does the descending limb of the nephron loop do to urine?

A

concentrates urine

45
Q

What does the ascending limb of the nephron loop due to urine?

A

dilutes urine

46
Q

What limb of the nephron loop is permeable to water and impermeable to solutes?

A

descending limb

47
Q

What limb of the nephron loop is impermeable to water and permeable to solutes?

A

ascending limb

48
Q

What removes solutes and water from the nephron loop to maintain the gradient?

A

vasa recta

49
Q

What is highly sensitive to hormones and uses the gradient?

A

collecting duct
