Underwater physiology
Underwater physiology examines how living organisms adapt to life beneath the water's surface. For humans, this involves understanding how pressure affects the body; for instance, as we dive deeper, increased pressure can impact our lungs and blood. Our bodies also need more oxygen since it is harder to breathe underwater. Marine animals have specialized adaptations, such as gills to extract oxygen from water and blubber for insulation. Understanding these adaptations helps scientists explore how life thrives in aquatic environments and informs practices in diving and marine conservation.

Underwater physiology studies how the human body functions in aquatic environments. When submerged, our bodies face unique challenges, such as changes in pressure, temperature, and oxygen availability. For example, increased pressure can affect how gases are absorbed in our blood, leading to risks like decompression sickness. Cold water can cause body temperatures to drop, affecting muscle and organ function. Additionally, the buoyancy of water reduces strain on joints and muscles. Understanding these factors is crucial for activities like scuba diving and underwater work to ensure safety and optimize performance while exploring underwater environments.
