Both inhalation and exhalation are part of the respiratory process where air is exchanged in the lungs. During inhalation, the diaphragm and intercostal muscles contract to expand the chest cavity, allowing air to enter the lungs. During exhalation, these muscles relax, and the chest cavity decreases in size, forcing air out of the lungs. The key difference is the direction of airflow: inhalation is the process of taking air into the lungs, while exhalation is the process of expelling air from the lungs.
Inhalation.
"After the workout, take a deep inhalation to fill your lungs with fresh air." "The doctor instructed the patient to practice slow, controlled inhalation exercises to relax." "Be mindful of your breath and focus on the sensation of inhalation and exhalation during meditation." "Inhale deeply before diving into the cold water to prepare your body for the shock."
There are two phases in one breath: inhalation and exhalation. During inhalation, air is drawn into the lungs, and during exhalation, air is expelled from the lungs.

Static compliance decreases due to factors like pulmonary fibrosis, lung tissue scarring, or poor surfactant function which results in reduced ability of the lungs to stretch and expand during inhalation, leading to decreased lung capacity and restricted airflow.
The diaphragm contracts during the inhalation phase of respiration. When it contracts, it moves downward, increasing the volume of the thoracic cavity and causing air to rush into the lungs.
During inhalation, the thoracic cavity expands as the diaphragm contracts and the rib cage moves up and out. This creates more space for the lungs to expand and fill with air.
The ribs expand during inhalation. This creates negative pressure on the lungs and draws air into them. During exhalation the rib cage gets smaller, compressing the lungs, in a sense, and forcing air out.
So the esophagus can expand when the bolus( call of food) travels down
