Accepted Answer

Hello everyone and welcome to today's video. We need to identify the incorrect statement during the process of inspiration. Let's go over our answer choices so that women begin solving this. We have that the external intercostal muscles contract when we inspire or conspiratorial muscles contract. And these involve the external intercostal and the diaphragm. So this is definitely a correct answer choice. Since we're looking for the incorrect one. We're going to cancel this out. Then we have the the volume of the thoracic cavity decreases. Well remember that the diaphragm and the external intercostal muscles are contracting. The recent or contracting is to allow more space for this thoracic cavity and for it to enlarge and allow the air into the body. So the volume of the thoracic cavity is actually going to increase. Not decrease because of this. This is an incorrect statement and we're going to be not canceling it out as part of our answer choices. Let's move on to answer choice. C the diaphragm contracts and move downwards. We already stated that these conspiratorial muscles social. The diagram are going to contract. So this part is correct and it's also going to move down more to allow the thoracic cavity again to enlarge. So because of this this is a completely correct answer choice and we're going to cancel it out because we're looking for the incorrect one which in this case is going to be answer choice. The the volume of the thoracic cavity does not decrease during inspiration. It increases. There is a final answer to your question and I really hope this video helped you
