What does it mean to constrict?

• A. To get larger
• B. To get smaller
• C. To become more visible
• D. To increase in activity

Answer: (B)

Constrict means to make something smaller or narrower. In a medical context, the term is often used to describe the narrowing of blood vessels or airways, which can occur as a response to various physiological stimuli. When something constricts, it reduces in size, which is an essential concept in understanding how the body responds to different conditions, such as stress or injury. This mechanism can impact blood flow and oxygen delivery, which are critical for a combat medic to understand when assessing a patient's condition or providing care. The other choices do not accurately reflect the definition of constrict; they suggest increased size or visibility rather than a decrease in dimension.
