Indicate whether the following statements are true or false:
Micturition is carried out by a reflex.
True. Micturition is carried out by a reflex.
ADH helps in water elimination, making the urine hypotonic.
False. ADH facilitates water reabsorption, not water elimination. It helps make the urine hypertonic, not hypotonic.
Protein-free fluid is filtered from blood plasma into the Bowman’s capsule.
True. Protein-free fluid is filtered from blood plasma into the Bowman's capsule.
Henle’s loop plays an important role in concentrating the urine.
True. Henle's loop plays an important role in concentrating the urine.
Glucose is actively reabsorbed in the proximal convoluted tubule.
True. Glucose is actively reabsorbed in the proximal convoluted tubule.
Explanation
Based on the textbook context: (a) Micturition is associated with the urinary bladder and is a reflex action. (b) The matching exercise clearly shows ADH is associated with 'Water reabsorption' (Column II), which contradicts the statement about water elimination. ADH promotes water reabsorption, concentrating urine. (c) Glomerular filtration produces a protein-free filtrate in Bowman's capsule. (d) The context explicitly states that the descending limb of Henle's loop 'concentrates the filtrate as it moves down' and plays 'a significant role in the maintenance of high osmolarity of medullary interstitial fluid.' (e) The proximal convoluted tubule (PCT) is mentioned in the context as part of the nephron where reabsorption processes occur.
