Answer 1

36.b.efferent.

Efferent arterial vasoconstrict to a greater degree than other arterials. Afferent arterials can also vascoconstrict but only to a small degree.

37.a. renal medulla

Renal medulla provides generalized vasoconstriction by producing epinephrine.

38.b.ascending loop of Henle's water concentration.

39.b.more

40.a.less

41.b.aldosterone secretion

42.b.renin

43.a.true

44.b.false
