Belégzések

Belégzések refers to the act of inhaling air into the lungs. This is a fundamental process of respiration, essential for life. Inhalation is an active process, meaning it requires muscular effort. The primary muscle involved is the diaphragm, a dome-shaped muscle located at the base of the chest cavity. When the diaphragm contracts, it flattens and moves downward, increasing the volume of the chest cavity. Simultaneously, the external intercostal muscles, located between the ribs, contract and pull the rib cage upward and outward, further expanding the chest. This expansion reduces the air pressure within the lungs compared to the atmospheric pressure outside the body. Consequently, air rushes into the lungs to equalize the pressure, a process known as inspiration or inhalation. The volume of air inhaled can vary depending on the body's needs, from a normal resting breath to a deep, forceful inhalation. Factors such as physical activity, emotional state, and lung health can influence the depth and rate of belégzések. The inhaled air, rich in oxygen, then travels through the airways to the alveoli, where gas exchange occurs, supplying the body's cells with oxygen and removing carbon dioxide.
