Q

Where do the kidneys sit relative to vertebrae?

A

T12 to L2

17
Q

What cells is the PCT made of?

A

Epithelial cells with long microvilli

18
Q

PCT absorbs about __% of filtrate.

A

65%

19
Q

How many glomeruli does each kidney have?

A

1,000,000

20
Q

Transport maximum

A

Some substances (glucose, amino acids, phosphate) have a maximum that can be absorbed. So if filtration exceeds reabsorption maximum … they will be excreted in the urine.

21
Q

Can the thin descending loop of henle reabsorb water?

A

Yes.

22
Q

Is the thick ascending loop permeable to water?

A

No.

23
Q

Which part of the kidneys are the glomeruli in?

A

Cortex

24
Q

What makes the DCT special?

A

It is subject to hormonal control

Aldosterone.

25
Q

Which type of nephron sets the concentration gradient?

A

Juxtaglomerular

only 30% of nephrons

26
Q

Atrial natriuretic factor

A

Released by atrial myocardium in response to HTN
Inhibits sodium and water reabs.
Decreases BP

27
Q

Which hormone acts on the collecting ducts?

A

ADH

28
Q

What is glucose cotransported with?

A

Sodium

29
Q

What is glucose cotransported with?

A

Sodium

30
Q

Whats the osmolarity in the cortex?

A

300
