Answer:
The coupling of blood flow with the amount of air reaching the alveoli is known as ventilation-perfusion V/Q matching.
Step-by-step explanation:
V/Q matching is a vital process that harmonizes the distribution of airflow and blood flow in the lungs, ultimately maximizing gas exchange efficiency. Its objective is to align well-ventilated lung regions with well-perfused capillaries, allowing for optimal uptake of oxygen and release of carbon dioxide. The seamless coordination of ventilation and perfusion in V/Q matching is crucial for sustaining the proper balance of gases in the respiratory system, thereby ensuring effective pulmonary function.
