belégzésekor

Belégzésekor refers to the act of inhaling or breathing in. It is a fundamental physiological process for all aerobic organisms, allowing them to take in oxygen from the environment. This oxygen is essential for cellular respiration, the process by which cells generate energy. The mechanism of inhalation involves the contraction of the diaphragm and intercostal muscles, which increases the volume of the thoracic cavity. This expansion lowers the pressure within the lungs relative to the external atmosphere, causing air to flow into the respiratory passages and lungs. The air travels through the nose or mouth, pharynx, larynx, trachea, bronchi, and finally into the alveoli of the lungs, where gas exchange occurs. Oxygen diffuses from the alveoli into the bloodstream, while carbon dioxide is released from the blood into the alveoli to be exhaled. Belégzésekor is a crucial part of the respiratory cycle, working in conjunction with exhalation to maintain oxygen levels and remove waste products from the body. Disruptions to this process can lead to various respiratory issues.
