Explanation / Answer

1. In renal circulation, blood flows from segmental arteries directly into the interlobar arteries.

Explanation: The blood is supplied to the kidneys by the renal arteries which have branched from the abdominal aorta inferior. Each renal arteries branches further to form the segmental arteries. These segmental arteries on entering the hilus of the kidney divide into interlobar arteries.

2. The renal corpuscle consists of glomerulus and Bowman's capsule.

Explanation: The renal corpuscle consists of the glomerulus which is a tangled cluster of blood capillaries and Bowman's capsule which is a sac like structure surrounding the glomerulus.

3. The medulla is the region of the kidney that houses many collecting ducts.

Explanation: The medulla consists of pyramids which are formed by the collecting duct.

4.The longest coiled renal tubule that immediately exists the glomerular corpuscle is the proximal convoluted tubule.

Explanation: The proximal convoluted tubule is the first segment that receives the plasma filtrate from the glomerular corpuscle and is ~14 mm long (which is the longest).
