36. B. Blood hydrostatic pressure.
Filtration of blood in the glomeruli is promoted by blood hydrostatic pressure and opposed by blood colloid osmotic pressure and capsular hydrostatic pressure.
37. A. renal blood vessels.
Sympathetic nerves from the renal plexus are distributed to the renal blood vessels.
38. C. Simple cuboidal epithelial cells.
The cells making up the proximal and distal convoluted tubules are simple cuboidal epithelial cells. These cells are specialized to do selective absorption and secretion.
39. B. The glomerulus and the glomerular (Bowman's) capsule.
The renal corpuscle consists of two parts - the glomerulus and the Bowman's capsule.
