Most abundant ion in intracellular fluid

17
Q

Main protein buffer in blood

A

Hemoglobin

18
Q

Percent of extracellular fluid in body is interstitial

19
Q

How kidneys help control pH of body fluids

A

Allow for pH adjustments
- H ions and bicarbonate ions can be reabsorbed into blood/secreted into filtrate as needed for pH adjustment

20
Q

Main hormone secreted by developing ovarian follicles

21
Q

Functions of LH

A

Stimulates cells in testes to produce testosterone

22
Q

What sperm fuses with during fertilization

23
Q

Direct effect of the inhibition of release of GnRH from hypothalamus

A

Testes will not grow at puberty and they will not produce their own testosterone and sperm

24
Q

Diploid cells produced by an embryonic germ cell

A

Spermatogonia

25
