Respiratory physiology
Respiratory physiology
Respiratory physiology (pronunciation: /rɪˈspɪrətɔːri fɪzɪˈɒlədʒi/) is the branch of physiology that pertains to the study of the respiratory system, including the lungs, bronchi, trachea, and other structures involved in the process of respiration.
Etymology
The term "respiratory physiology" is derived from the Latin respirare which means "to breathe" and the Greek physiologia which means "study of nature".
Overview
Respiratory physiology involves the study of the mechanical, physical, and biochemical processes that contribute to the exchange of gases in the body, namely oxygen and carbon dioxide. It also includes the study of how the body responds to changes in the levels of these gases in the blood, and how these responses affect other bodily functions.
