Kilégzésben

Kilégzésben is a Hungarian term that translates to "in exhalation" or "during exhalation" in English. It refers to the phase of breathing when air is expelled from the lungs. This process is a fundamental part of respiration, the mechanism by which organisms exchange gases with their environment.

During kilégzésben, the diaphragm relaxes and moves upward, and the intercostal muscles between the ribs relax, causing the chest cavity to decrease in volume. This reduction in volume increases the pressure within the lungs, forcing air out. The expelled air is rich in carbon dioxide and depleted of oxygen, having fulfilled its role in cellular respiration.

The act of kilégzésben is involuntary for the most part, regulated by the respiratory centers in the brainstem. However, it can also be consciously controlled, allowing for actions like speaking, singing, or playing wind instruments. The rate and depth of exhalation are influenced by various factors, including physical activity, emotional state, and the presence of respiratory conditions. Understanding kilégzésben is crucial in fields such as physiology, medicine, and sports science, as it directly relates to oxygen intake and carbon dioxide removal, vital for maintaining bodily functions.
