ANS: B
The macula densa are sodium-sensing cells. The epithelium has specialized cells called podocytes from which pedicles (foot projections) radiate and adhere to the basement membrane. Mesangial cells lie between and support the capillaries. Mesangial cells have phagocytic ability similar to that monocytes, release inflammatory cytokines, and can contract to regulate glomerular capillary blood flow. The loop of Henle is where fluid reabsorption occurs.
