Question
Please answer both questions:
1. If congestive heart failure has progressed to the point of venos congestion in the systemic circuit, the kidnets will receive less blood flow;this would result in:
a. increased aldosterone secretion
b. increased EPO secretion
c. decreased urine formation
d. all of the above
2. The functional structure of the respiratory system has all of the following chararcteristics which make it suitable for gas exchange, EXCEPT
a. high surface tension
b. large surface area
c. thin walls
d. closeness to capillaries
Explanation / Answer
1. If congestive heart failure has progressed to the point of venos congestion in the systemic circuit, the kidneys will receive blood flow which result in increased aldosterone secretion.
(a) increased aldosterone secretion.
Kidneys caused as a result of reduced blood flow to the kidneys,which leads to the secretion of aldosterone which stimulates absorption of sodium by the kidneys and regulates the balance of salt and water in the blood stream.
2. The functional structure of the respiratory system has all of the following characteristics which make it suitable for gas exchange except:
(a) high surface tension
The respiratory system is a complex biological system comprised of several organs which facilitate the inhalation and exhalation of Oxygen and carbon-dioxide in living organisms.
The main characteristic is it has large surface area.
