Aerospace Physiology
Aerospace Physiology (pronounced: air-o-space fiz-ee-ol-o-gee) is a branch of physiology that studies the effects of flight and space travel on the human body. The term is derived from the Greek words "aero" meaning air, "space" referring to the universe beyond the Earth's atmosphere, and "physiology" meaning the study of the functions and mechanisms of the body.
History
The study of Aerospace Physiology began in the early 20th century with the advent of aviation. As humans began to fly at higher altitudes and for longer durations, the need to understand the physiological effects of these conditions became apparent. The field expanded with the advent of space exploration in the mid-20th century, as scientists sought to understand the effects of zero gravity and other space conditions on the human body.
Key Concepts
Aerospace Physiology encompasses several key concepts, including:
- Hypoxia: A condition that occurs when the body or a region of the body is deprived of adequate oxygen supply. Hypoxia is a significant concern in high-altitude flight and space travel.
- Barotrauma: Injury caused by changes in barometric pressure, such as those experienced during rapid ascent or descent in flight.
- Radiation Exposure: In space, astronauts are exposed to levels of radiation much higher than on Earth, which can have various physiological effects.
- Microgravity Effects: The effects of living in a low-gravity environment, such as those experienced by astronauts in space, on various bodily systems.
Related Fields
Aerospace Physiology is closely related to several other fields, including Aviation Medicine, Space Medicine, and Environmental Physiology.
