Respiration is the biological process by which living organisms, including humans, exchange gases with their environment. This process involves the intake of oxygen and the release of carbon dioxide, which is essential for the production of energy through cellular respiration. Respiration can occur through different mechanisms, such as aerobic respiration (with the presence of oxygen) or anaerobic respiration (without oxygen). It is a fundamental process for the survival of all organisms and plays a crucial role in maintaining homeostasis and energy production in the body. Researchers in the field of respiration study various aspects of this process, including the mechanisms involved, the regulation of breathing, and the impact of respiratory disorders on health and disease.
