The windpipe may be blocked by a swelling; by a severe injury to the neck, nose, or mouth; by a large foreign object; by paralysis of the throat muscles; or by a tumor.
No
To completely block any air from entering the respiratory system, the trachea (windpipe) would need to be obstructed. This would prevent air from reaching the lungs where gas exchange occurs. Additionally, blockage of the bronchial tubes leading into the lungs would also prevent air from entering the respiratory system.

Plateau pressure is determined by the compliance of the lungs and chest wall, as well as the volume of air in the lungs at end-inspiration. It is affected by factors such as lung disease, obesity, and the presence of chest wall abnormalities. Monitoring plateau pressure is important in managing mechanical ventilation in critically ill patients to prevent lung injury.
The diaphragm is a dome-shaped muscle located below the lungs. Its main function is to help with breathing by contracting and expanding to create a vacuum that allows the lungs to fill up with air during inhalation and push air out during exhalation.
This varies between different people, so a sporty persons lungs would have adapted to hold my air than a normal persons. Also a pro swimmer would have more air capacity in their lungs so they could hold it for longer.
Epiglottis
Blood that has perfused the lungs and is now oxygenated collects into the pulmonary veins to travel back to the heart. Once reaching the heart, oxygenated blood from the lungs enters the left atrium. The left atrium collects blood from the lungs
Oxygen is taken in by the lungs through the process of inhalation. When you breathe in, air containing oxygen enters the lungs through the trachea and bronchial tubes, eventually reaching the alveoli where oxygen is absorbed into the bloodstream.
To prevent over inflation of the lungs.
