Will Rate, Thank you!

Filtration is a passive process (no energy expenditure required), but glomerular filtration requires: Oa a high pressure gradient in the glomerular arteries Ob.systemic blood pressure below 100/60 c. an efferent arteriole with a diameter greater than that of the afferent arteriole Od.all of the above QUESTION 4 We typically have more concentrated urine just after waking. A hormone or substance which stimulates the kidneys to conserve water is: a. ANH b. ADH C. caffeine Od none of the above

Explanation / Answer

Answer 3 a ..high pressure gradient in the glomerular arteries.

Efferent arteriole diameter should be narrower than afferent (that brings blood to the glomerulus)

Answer 4 b.. adh.. that is antidiuretic hormone

It is also known as vasopressin. It helps in water reabsorption. Hence more concentrated urine
