Explain the process of Inspiration under Normal Conditions.
Answer:
The process of inspiration under normal conditions takes place when the pressure within the lungs is less than the atmospheric pressure. It starts with the contraction of the diaphragm which increases the volume of the thoracic chamber in the anteroposterior axis. External intercostal muscles contracts and lifts up the ribs and sternum. It increases the volume of the thoracic chamber in the dorsoventral axis. The pulmonary volume increases after the increase in the thoracic volume, which decreases the intra-pulmonary pressure to less than the atmospheric pressure. The negative pressure that is created inside forces the air from outside to move into the lungs, completing the process of inspiration.
