Belélegzés

Belélegzés is the Hungarian word for inhalation or breathing in. It refers to the process by which air, containing oxygen and other gases, enters the respiratory system. This is the first phase of the breathing cycle, which also includes exhalation. During belélegzés, the diaphragm contracts and flattens, and the intercostal muscles contract, lifting the rib cage. This action increases the volume of the thoracic cavity, which in turn decreases the pressure within the lungs. As a result, air flows from the higher-pressure atmosphere into the lower-pressure lungs. This oxygen-rich air then travels through the airways to the alveoli, where gas exchange takes place, providing the body with the oxygen it needs for cellular respiration. The rate and depth of belélegzés can vary depending on factors such as physical activity, emotional state, and overall health. For example, during strenuous exercise, belélegzés becomes deeper and more frequent to meet the increased oxygen demand of the muscles. In contrast, during rest or sleep, breathing is typically slower and shallower. The mechanics of belélegzés are essential for life, ensuring the continuous supply of oxygen to all bodily tissues and organs.
