Correct Answer: B
Solution :
Ultrafiltration refers to filtration of very fine particles having molecular weight less than 68,000 daltons through malpighian corpuscle. Concentration of urine refers to water absorption from glomerular filtrate as a result of hyperosmolarity in the medulla created by counter-current mechanism in Henle's loop. Urine is carried from kidney to bladder through ureter. Urinary bladder is concerned with storage of urine.
