Andningsfysiologiska processer (respiratory physiological processes) refer to the various functions and mechanisms that occur during breathing to allow for gas exchange between the body and the environment. These processes include:

1. Ventilation: This is the movement of air into and out of the lungs, which is achieved through the contraction and relaxation of the diaphragm and intercostal muscles.
2. External respiration: This refers to the exchange of gases (oxygen and carbon dioxide) between the alveoli in the lungs and the blood in the pulmonary capillaries.
3. Internal respiration: This is the exchange of gases between the blood in the systemic capillaries and the body's cells.
4. Gas transport: Once oxygen has been taken up by the blood, it is transported to the body's cells through the circulatory system. Carbon dioxide, a waste product produced by cells, is also transported back to the lungs for excretion.
5. Regulation of respiratory rate and depth: The body has mechanisms in place to regulate the rate and depth of breathing to ensure that adequate amounts of oxygen are supplied to the body's cells while maintaining a stable concentration of carbon dioxide in the blood.

These processes work together to maintain homeostasis in the body by providing cells with the necessary oxygen for metabolism and removing waste products such as carbon dioxide.
