Innöndunarloftinu

Innöndunarloftinu is a term that can be translated from Icelandic as "inhaled air" or "inspired air." It refers to the air that is taken into the lungs during the process of breathing in. This air is a mixture of gases, primarily nitrogen, oxygen, argon, and a smaller amount of carbon dioxide, along with trace amounts of other gases. When a person inhales, the diaphragm contracts and the rib cage expands, increasing the volume of the thoracic cavity and drawing air into the lungs.

The composition of inhaled air differs from the air that is exhaled. While inhaled air has a higher percentage of oxygen, the air exhaled from the lungs has a lower percentage of oxygen and a higher percentage of carbon dioxide. This is due to the process of gas exchange that occurs in the alveoli of the lungs, where oxygen is absorbed into the bloodstream and carbon dioxide is released from the blood. The temperature and humidity of the inhaled air are also altered as it passes through the respiratory passages. The nasal cavity, for instance, warms and humidifies the incoming air, preparing it for the delicate tissues of the lungs. Understanding the nature and processing of innöndunarloftinu is fundamental to the study of respiratory physiology and the maintenance of life.
