Question
Chapter 20.2, Problem 2CC
Summary Introduction
To determine: Whether the people suffering from vasopressin V2 receptor deficiency have dilute or concentrated urine.
Introduction: Vasopressin is a hormone released by the pituitary gland. It is found in the nephrons present in the kidney. The role of vasopressin is important in the functioning of the nephron.

Which of the following is an effect of ADH interaction with the vasopressin receptor?
Answers A - D
A
Increased expression of Na+/K+-ATPase on the basolateral membrane of the distal segments
Increased expression of ENAC on the apical membrane of the distal segments
Increased expression of aquaporin 2 on the apical membrane of collecting duct cells
Increased expression of aquaporin 3 on the basolateral membrane of collecting duct cells
What three stimuli control vasopressin secretion? What is the most potent stimulus for vasopressin release?
Atrial Natriuretic Peptide helps to reduce overall blood pressure in a variety of ways. One way is by increasing Glomerular Filtration Rate.
a. Why/how would increasing GFR cause decreased blood pressure? b. To increase GFR, would Atrial Natriuretic Peptide cause constriction or dilation of afferent arterioles at the kidneys? The efferent arterioles?
