hingamisõhuga

Hingamisõhuga refers to the air that is inhaled and exhaled by a living organism during respiration. This atmospheric mixture is crucial for the survival of most life forms on Earth. The primary component of breathable air is nitrogen, making up approximately 78%, followed by oxygen at about 21%. The remaining 1% consists of various trace gases, including argon, carbon dioxide, neon, helium, and others.

Oxygen is the vital element in this mixture that facilitates cellular respiration, the process by which organisms convert nutrients into energy. During inhalation, oxygen-rich air enters the lungs, where it diffuses into the bloodstream. This oxygen is then transported to cells throughout the body. In exhaled air, the oxygen content is significantly reduced, and the concentration of carbon dioxide, a waste product of cellular respiration, is increased.

The composition of hingamisõhuga can be influenced by environmental factors such as altitude, pollution, and the presence of specific industrial emissions. High altitudes, for instance, have a lower partial pressure of oxygen, making breathing more challenging. Air pollution can introduce harmful substances into the inhaled air, posing health risks. Maintaining the quality of breathable air is therefore essential for public health and the health of ecosystems. Natural processes like photosynthesis by plants play a key role in replenishing the oxygen in the atmosphere.
