Select the correct events that occur during inspiration.(a) Contraction of diaphragm(b) Contraction of external inter-costal muscles(c) Pulmonary volume decreases(d) Intra pulmonary pressure increases
(c) and (d)
(a), (b) and (d)
only (d)
(a) and (b)
To solve this problem, we need to identify the correct events that occur during inspiration. Let's analyze each event:(a) Contraction of diaphragm: - During inspiration, the diaphragm contracts and moves downward, increasing the thoracic cavity's volume.(b) Contraction of external inter-costal muscles: - The external inter-costal muscles contract, lifting the ribs and further expanding the thoracic cavity.(c) Pulmonary volume decreases:
