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 bowman's capsule.
(d) Henle's loop plays an important role in concentrating the urine.
(e) Glucose is actively reabsorbed in proximal convoluted tubule.
(f) Human urinary system is simple tubular system like malpighian tubule.

• A. $\text{True}-a,b,f,\text{False}-c,d,e$
• B. $\text{True}-b,e,f,\text{False}-a,c,d$
• C. $\text{True}-d,e,f,\text{False}-a,b,c$
• D. $\text{True}-a,c,d,e,\text{False}-b,f$

Answer 1

The correct option is D $\text{True}-a,c,d,e,\text{False}-b,f$

a) The process of release of urine is called micturition and the neural mechanisms causing it is called the micturition reflex.
b) $ADH$ facilitates water reabsorption from $DCT$ and collecting duct thus prevents diuresis or decreases volume of urine.
c) The blood which is filtered by bowman’s capsules does not have $RBC$ and proteins. The process is called ultra filtration.
d) Henle’s loop plays an important role in concentrating the urine by the process called counter current.
e) Glucose, amino acids, fatty acids are reabsorbed by active transport in $PCT$.
f) Human urinary system is systematic in complex which consist of a pair of kidneys, one pair of ureters, a urinary bladder and a urethra.
