The process of filtration occurs in the:

• proximal tubule

• renal corpuscle

• distal tubule

• collecting duct

Podocytes in fenestrated glomerular capillaries prevent the filtration of:

• amino acids

• glucose

• albumin

• nitrogenous wastes

The myogenic mechanism acts to restore the glomerular filtration rate (GFR) by changing:

• tubular secretion of metabolic wastes

• vessel diameter

• blood pH

• blood pressure

How does the vessel diameter of the afferent arteriole change in response to high blood pressure in order to maintain GFR?

• vasoconstrict

• vasodilate

• the afferent arteriole has no effect on GFR

• vasoconstrict, then vasodilate

Jasmine has high blood pressure and an increased GFR. How does tubuloglomerular feedback restore normal GFR?

• JG cells decrease production of renin

• afferent arteriole vasodilates

• JG cells increase production of renin

• efferent arteriole constricts

How does ANP contribute to a decrease in blood volume and systemic blood pressure?

• constricts afferent arteriole and dilates efferent arteriole

• dilates afferent arteriole and constricts efferent arteriole

• dilates both the afferent and efferent arterioles

• constricts both the afferent and efferent arterioles

Reabsorption of filtered glucose from the filtrate into the cells of the proximal tubule is by:

• facilitated diffusion

• simple diffusion

• secondary active transport

• antiport
