Which term means to make smaller or narrower by binding or squeezing?

The term that means to make smaller or narrower by binding or squeezing is "constrict." In various contexts, such as biology or physiology, constriction refers to the process of narrowing blood vessels or muscles when they contract. This action often results in a reduction of space or volume.

For example, in the human body, the constriction of blood vessels can affect blood flow and pressure. Similarly, in a more general context, to constrict something can mean to tighten it, whether that be physically (as in binding cloth) or metaphorically (as in limiting options or resources). Understanding this term helps illuminate various processes in both natural and applied sciences, enhancing comprehension of how systems maintain balance or respond to stimuli.
