Q. Choose the correct ones I. Vasa recta is lacking in cortical nephrons II. Maximum number of nephrons in kidney are juxta-medullary type III. DCT of many nephorns open into collecting tubule IV. During summer when body loses lot of water by evaporation, the release of ADH is suppressed V. When someone drinks lot of water, ADH release is suppressed VI. Exposure to cold temperature stimulates ADH release VII. An increase in glomerular blood flow stimulates formation of angiotensin II The correct option is
A) All except I and IV
B) All except V and VII
C) All except I and V
D) All except II and VI
Explanation
Vasa recta is present in cortical nephron at the juxta medullary region for conserving the water (counter current mechanism). During summers, when body loses lot of water by evaporation, the release of ADH is increased due to decrease of water loss
