Accepted Answer

Hello everyone. And in today's video we have the following problem. The parasympathetic branch of the autonomic nervous system is involved in. And so before we jump into this problem let us break down the autonomic nervous system into the two branches that make it up. And these branches are going to be the sympathetic branch which is not mentioned directly in the problem. And the parasympathetic branch, which is what the problem is. My mostly asking about Now the sympathetic branch is mostly involved with processes such as fight or flight. So processes that require this increase in the rate of respiration and just make us more active than we previously were. Well, the parasympathetic nervous system is involved in rest and digest. So it is mostly mostly kicks in in periods of rest. So after we eat for example and we're digesting our food and we're sitting down. That's when the parasympathetic branch of the autonomic nervous system kicks in. So now that we know this, let us quickly go over answer choices so that we can use this information to solve the problem. Beginning the answer choice B increasing the rate of respiration. So if we are in a situation of fight or flight or rate of respiration is going to increase, we're going to respond more and so we're going to cancel this out. Then we have see increasing the release of epinephrine epinephrine and neurotransmitter. Which is a big part of the sympathetic nervous system. It is going to make us more active. So we're going to cancel this out as well, then we have increasing the blood flow through two muscles. We are in a fight or flight situation or we or we and we want to run or we want to fight. Then these sympathetic branch of the of the autonomic nervous system is going to kick in to increase blood flow to the muscles so that we can use it. So we're going to cancel this out as well. And so it all leads us with answer choice, a acceleration of the rate of digestion. And as we can see here in our definition or just or summary of the parasympathetic nervous system, it involves digestion. So that's when we are resting and digesting. The parasympathetic nervous system will in fact accelerate the rate of digestion. And so answer choice A is going to be your final answer for the question. I really hope this video helps you.
