explain process of inspiration and expiration un detail ?
Answers
Answer:
Oxygen is transferred to the lungs when the thoracic cavity expands as a result of the contraction of diaphragm. ... Lungs diffuse the carbon dioxide inside them and the diaphragm relaxes which result in the relaxation of external intercostal muscles thereby decreasing the thoracic cavity.
Answer:
please mark me as brainliest..
Explanation:
When the lungs inhale, the diaphragm contracts and pulls downward. ... As a result, air rushes in and fills the lungs. The second phase is called expiration, or exhaling. When the lungs exhale, the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases..
Inspiration (inhalation) is the process of taking air into the lungs. It is the active phase of ventilation because it is the result of muscle contraction. During inspiration, the diaphragm contracts and the thoracic cavity increases in volume. This decreases the intraalveolar pressure so that air flows into the lungs..
