Arrange the following steps of expiration in correct sequence and select the correct option thereafter.(A) Increase in intra-pulmonary pressure to slightly above the atmospheric pressure.(B) Returning of diaphragm and sternum to their normal positions.(C) Expulsion of air from the lungs. (D) Relaxation of the diaphragm and the inter-costal muscles.(E) Reduction in thoracic volume and thereby the pulmonary volume.Options :D,E,B,A,CA,D,B,E,CD,B,E,A,CE,B,A,D,C

Select all of the following that describes expiration.Multiple select question.Pressure in the lungs decreases.Rib cage moves down and in.Diaphragm relaxes and moves up.Internal intercostal muscles pull the ribs inward.

Q14. Which of the following occurs during expiration?a) The intrapulmonary pressure is less than atmospheric pressureb) The diaphragm relaxes and domes up.c) The rib cage lifts up and out.d) The intrapleural pressure is greater than intrapulmonary pressure

When the diaphragm and external intercostal muscles contract: choose one• none of these conditions would occur• intrapleural pressure decreases• intrapulmonary pressure increasesO expiration occurs• volume of the lungs decreases

Q5. Which of the following statements about lung function describes the process of 'expiration'1 pointThe diaphragm and external intercostal muscles contract, drawing air into the lungs.The diaphragm and external intercostal muscles contract, forcing air out of the lungs.The diaphragm and external intercostal muscles relax, drawing air into the lungs.The diaphragm and external intercostal muscles relax, forcing air out of the lungs.

The volume of air remaining in the respiratory passages and lungs after forceful expiration is called:
