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

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.

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

Which of the following events does not occur during exhalation in human beings?The inter-costal muscles pull the ribs inwardlyThe volume of thoracic cavity increasesHigh pressure area is created inside the thoracic cavityDiaphragm becomes dome-shaped

Which of the following statements is / are FALSE? (select all appropriate)Question 45Answera.During inhalation, air enters the lungs by moving down its pressure gradient, from an area of higher pressure outside the body to an area of lower pressure within the lungs.b.During forced breathing, both inhalation and exhalation are active processes that make use of muscle contractions.c.Pressure and volume are inversely related (Boyle's law)d.During exhalation, air exits the lungs by moving against its pressure gradient, from an area of lower pressure within the lungs to an area of higher pressure outside the bodye.The contraction of the diaphragm and external intercostal muscles is the first step of

Which of the following statement(s) is(are) true regarding exhalation? Question 26 options: there is a decrease in both the lung volume and pressure in the lungs there is a increase in the lung volume and diaphragm moves downward there is a decrease in lung volume and the diaphragm moves downward there is a decrease in lung volume and the diaphragm moves upward there is a increase in the lung volume and the diaphragm moves upward
