Walter Bradford Cannon
Walter Bradford Cannon was an influential American physiologist best known for describing the body's "fight or flight" response, which is how our body reacts to stress or danger. He studied how the nervous system helps regulate internal functions like blood pressure and temperature, emphasizing the importance of homeostasis—maintaining stable internal conditions. Cannon's research laid the groundwork for understanding how our body responds to stress, and he contributed significantly to the fields of physiology and medicine by highlighting the dynamic balance of bodily systems working together to keep us healthy.
