Question

Refer to the diagram of the nephron given below and answer the questions.

(a) Where does ultrafiltration occur?

(b) Which structure contains urine?

• A. (a) 1, (b) 7
• B. (a) 2, (b) 7
• C. (a) 3, (b) 2
• D. (a) 1, (b) 3

Answer 1

The correct option is B

(a) 2, (b) 7

(a) In the given figure, 2 is glomerulus. The process of ultrafiltration occurs in the glomerulus part of the nephron.

(b) In the given figure, 7 represent collecting duct. Urine gets collected inside the collecting duct after the selective absorptions of useful ions from the glomerular filtrate.
