Vedclass · Answer

(C) Urea enters the nephron through two primary mechanisms:$1$. $iii$. Ultrafiltration: During the process of glomerular filtration,urea is filtered along with water and other solutes into the Bowman's capsule (urinary space).$2$. $iv$. Inner medullary segment of collecting tubule: Urea is reabsorbed from the collecting duct into the medullary interstitium to maintain the osmolarity gradient. However,it also diffuses back into the thin ascending limb of the loop of Henle and the inner medullary collecting duct to maintain this cycle. Among the given choices,the entry of urea into the nephron occurs via ultrafiltration $(iii)$ and back-diffusion into the inner medullary collecting tubule $(iv)$ or thin ascending limb. Based on standard physiological models,the correct combination is $iii$ and $iv$. Since the provided options are limited,we identify the most accurate physiological pathways. Given the options,$iii$ and $iv$ represent the entry points for urea recycling and filtration.

Section $I$	Section $II$
$(i)$ Ultrafiltration	$(a)$ Henle's loop
$(ii)$ Concentration of urine	$(b)$ Ureter
$(iii)$ Transport of urine	$(c)$ Urinary bladder
$(iv)$ Storage of urine	$(d)$ Malpighian corpuscles
	$(e)$ Proximal convoluted tubules
