dýchanie

Dýchanie, also spelled as "dýchanie" in some languages, refers to the process of breathing, which is essential for the survival of all aerobic organisms. It involves the intake of oxygen and the expulsion of carbon dioxide. In humans, breathing is typically a involuntary process controlled by the brainstem, specifically the medulla oblongata and pons. The diaphragm, a dome-shaped muscle located at the base of the lungs, plays a crucial role in breathing by expanding and contracting to facilitate the movement of air.

The process of breathing can be divided into two phases: inhalation and exhalation. During inhalation, the diaphragm contracts, causing it to flatten and increase the volume of the thoracic cavity. This expansion draws air into the lungs. In exhalation, the diaphragm relaxes, returning to its dome shape and reducing the volume of the thoracic cavity, which forces air out of the lungs.

Breathing is vital for cellular respiration, the process by which cells convert oxygen into energy. It also helps regulate blood pH by removing carbon dioxide, a byproduct of cellular respiration. Abnormalities in breathing can lead to various health issues, including respiratory infections, asthma, and sleep apnea. Proper breathing techniques are essential for maintaining overall health and well-being.
