Question

Choose the option having all the incorrect statements:
I. Kidney is located ventrolaterally and it is a intra-peritoneal organ
II. Reactions of ornithine cycle occur in kidney to produce urea.
III. Net filtration pressure is dependent on glomerular hydrostatic pressure, glomerular osmotic pressure and capsular hydrostatic pressure.
IV. Descending limb of loop of Henle is impermeable to water.

• A. Only I and IV
• B. Only II and III
• C. Only III
• D. Only I, II and IV

Answer 1

The correct option is D Only I, II and IV

The correct statements for this question are:

I. Kidney is located dorsolaterally (on the back side and towards side) and it is a retroperitoneal organ (peritonium is present on the anterior side only or behind the peritonium).

II. Reactions of ornithine cycle occur in liver to produce urea. Ornithine cycle or urea cycle converts ammonia into urea in the human beings.

III. Net filtration pressure is dependent on glomerular hydrostatic pressure, glomerular osmotic pressure and capsular hydrostatic pressure. Net filtration pressure determines the glomerular filtration rate.

IV. Ascending limb of loop of Henle and all the parts beyond this region are impermeable to water and are only permeable to solutes.
