Pulmonary ventilation is the process of moving air into and out of the lungs, allowing for the exchange of oxygen and carbon dioxide between the atmosphere and the bloodstream. This essential function of the respiratory system is driven by pressure changes created by the diaphragm and intercostal muscles during inhalation and exhalation, facilitating gas exchange in the alveoli. It plays a crucial role in maintaining homeostasis and ensuring that body tissues receive adequate oxygen while removing carbon dioxide waste.
