Respiratory adaptation is the specific change that the respiratory system undergoes in response to the demands of physical exertion. Intense physical exertion, such as that involved in fitness training, places elevated demands on the respiratory system. Over time, this results in respiratory changes as the system adapts to these requirements. [1]
The adaptations of Tibetans to their hypoxic ventilatory response interact with other adaptations to promote successful reproduction. For example, Tibetans have evolved a greater oxygen saturation during infancy, leading to a lower rate of child mortality than experienced by non-adapted populations at altitude.
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
Respiratory physiology is the biological function of metabolic gas exchange. The complementary category for the anatomical structure of respiratory systems is Category:Respiratory system. The complementary category for the anatomical structure of respiratory systems is Category:Respiratory system.
In mammals, physiological respiration involves respiratory cycles of inhaled and exhaled breaths. Inhalation (breathing in) is usually an active movement that brings air into the lungs where the process of gas exchange takes place between the air in the alveoli and the blood in the pulmonary capillaries.

The tone of respiratory muscle is believed to be modulated by muscle spindles via a reflex arc involving the spinal cord. Drugs can greatly influence the rate of respiration. Opioids and anesthetics tend to depress ventilation, by decreasing the normal response to raised carbon dioxide levels in the arterial blood.
In very small animals, plants and bacteria, simple diffusion of gaseous metabolites is sufficient for respiratory function and no special adaptations are found to aid respiration. Passive diffusion or active transport are also sufficient mechanisms for many larger aquatic animals such as many worms, jellyfish, sponges, bryozoans and similar ...
