Hello everyone and welcome to today's video. Now, which of the following is not an effect of Al Ron. Now, we're going to be going over each of our answer choices and stating them before explaining why they are correct and incorrect. Now, let's begin by answer choice. Eight. It stimulates the activity of sodium potassium pumps and epithelial sodium channels. Well, this is going to be a true stem statement because aldosterone is going to have a positive effect on the sodium reabsorption on the sodium potassium channels or a TPAS. And therefore, we can cancel it out because this is a true statement and we're looking for the incorrect one. Now we have as b it increases sodium reabsorption because we're having increased activity of these sodium potassium pumps. Then we can say that sodium reabsorption is also increased. Therefore, we can cancel it out. Then we have the it increases blood volume while Doron is said to cause an iso osmotic increase in blood volume. And this is done because it increases the reabsorption of H2O from the filtrate. Therefore, we can cancel this out. Finally, we have see it decreases H2O reabsorption by osmosis. Well, remember from answer D we said that Aldo is going to increase this H2O reabsorption from the filtrate here. It is stated that it is decreased. Therefore, this is going to be an incorrect statement and we can highlight answer choice. C it decreases H2O reabsorption by osmosis. As a final answer to our question, I really hope this video helped you and I hope to see you on the next one.
