Certain drugs used to treat high blood pressure cause vasodilation of systemic arteries and arterioles, including those in the kidneys. Which choice reflects how the body would respond?
a. The GFR would increase and in response, the tubuloglomerular feedback mechanism would trigger dilation of the afferent arterioles.
b. The GFR would decrease and in response, the myogenic mechanism would trigger constriction of the efferent arterioles.
c. The GFR would increase and in response, tubuloglomerular feedback mechanism would trigger constriction of the afferent arterioles.
d. The GFR would decrease and in response, the tubuloglomerular feedback mechanism would trigger constriction of the afferent arterioles.
