kilégzése

Kilégzés is a Hungarian term that translates to "exhalation" or "expiration" in English. It refers to the process of breathing out, which is a fundamental part of the respiratory cycle in living organisms. During kilégzés, air is expelled from the lungs. This action is typically passive, meaning it relies on the relaxation of the diaphragm and intercostal muscles that contract during inhalation. However, it can also be an active process, involving forceful contraction of abdominal and intercostal muscles, as seen in coughing or sneezing.

The primary function of kilégzés is to remove carbon dioxide, a waste product of metabolism, from the body. This gas, along with other volatile waste products and water vapor, is transported by the blood to the lungs and then expelled into the atmosphere. The rate and depth of kilégzés are regulated by the respiratory center in the brainstem, which responds to changes in blood oxygen and carbon dioxide levels, as well as other physiological signals. In essence, kilégzés is the complementary counterpart to belégzés (inhalation), together forming the continuous cycle of respiration that sustains life by facilitating gas exchange.
