In the accompanying diagram of a human nephron the functional parts are labelled as A, B, C, D, E.

Study the diagram to answer the questions given

Choose the correct option:

Which of the following part of the nephron is not involved in tubular secretion?

1. Bowman’s capsule
2. PCT
3. DCT
4. Collecting Duct

Urinary excretion is equivalent to:
GF = Glomerular filtration.
TR = Tubular reabsorption.
TS = Tubular secretion.

1. GF + TR + TS 
2. GF – (TR + TS)
3. GF – TR + TS 
4. GF – TS + TR

Which of the following statement is correct with respect to to excretion?

1. Our lungs remove large amount of CO₂ (180 litres/day) and also significant quantity of water everyday
2. The ascending limb is permeable to water and also allows transport of electrolytes actively or passively
3. Conditional reabsorption of Na⁺ and water takes place in proximal convoluted tubule
4. Maximum water reabsorption takes place in proximal convoluted tubule, even in the presence of ADH

Match the items in Column - I with those in Column - II:

The parts of nephron situated in cortical region of kidney are

1. Loop of Henle, PCT, and collecting duct

2. Collecting duct, PCT, and malpighian corpuscle

3. PCT, DCT, and Loop of Henle

4. PCT, DCT and Malpighian corpuscle

Which one of the following statements is incorrect?

1. The medullary zone of the kidney is divided into a few conical masses called medullary pyramids projecting into calyces.

2. Inside the kidney the cortical region extends in between the medullary pyramids as renal pelvis.

3. glomerulus along with Bowman's capsule is called the renal corpuscle.

4. Renal corpuscle, proximal convoluted tubule (PCT), and distal convoluted tubule (DCT) of the nephron are situated in the cortical region of the kidney.
