Question

6) The vasa recta are associated with which structures in the kidney? (2pts) Afferent arterioles Glomeruli Cortical nephrons juxtamedullary nephrons 7) What type of response by the afferent arterioles would you expect if blood pressure increased? (2pts) The afferent arterioles would stimulate renin release. The afferent arterioles would not respond to blood pressure changes. The afferent arterioles would constrict. The afferent arterioles would dilate. 8) Extrinsic controls regulate glomerular filtration rate as a means of regulating pts) systemic blood pressure red blood cell production cardiac output urine formation 9) What would be the effect on urine output if sodium channels in the tubule cells were inhibited? (2pts) The volume would increase. The volume would decrease, then quickly resume. The volume would decrease by one-tenth the sodium concentration The volume would decrease by half the sodium concentration. 10) Why do high levels of potassium stimulate aldosterone secretion? (2pts)

Answer 1

6. Answer ; Juxtamedullary nephrons.

Reason ; Among the given option, the specified part of kidney which is mentioned in the given question, is associated with above mentioned parts. Other structure given in the options have no relation with these parts.

7. Answer ; The affernt arteriole would dialate.

Reason ; When there is a increasedf flow and there is an increase in amount of pressure, the underlying parts wil get enlarged, it means dialates, to respond to the situation. This is mentioned in the above statemnent. Other options are not relavent to this condition.

8. Answer ; Sytemic blood pressure.

Reason ; The primary objective of the mentioned action by the nerves to take care and maintain the blood pressure of the body, which can be achieved through this way. Hence the above mentioned answer is the appropriate one.

9. Answer ; The volume would increase.
