Question:

Indicate whether the following statements are true or false:
(a) Micturition is carried out by a reflex
(b) ADH helps in water elimination, making the urine hypotonic.
(c) Protein-free fluid is filtered from blood plasma into the Bowman’s capsule.
(d) Henle’s loop plays an important role in concentrating the urine.
(e) Glucose is actively reabsorbed in the proximal convoluted tubule.

Answer:

Statement True/False Explanation
(a) Micturition is carried out by a reflex. True Urine release involves a spinal reflex, though it can be voluntarily controlled.
(b) ADH helps in water elimination, making the urine hypotonic. False ADH conserves water, making urine more concentrated.
(c) Protein-free fluid is filtered from blood plasma into Bowman’s capsule. True Only small molecules pass; proteins are too large.
(d) Henle’s loop plays an important role in concentrating the urine. True It creates a salt gradient that helps reabsorb water.
(e) Glucose is actively reabsorbed in the proximal convoluted tubule. True PCT reabsorbs glucose, amino acids, and salts actively.
