Dilated

In the context of biological systems, 'dilated' (adjective) refers to something that has become wider, larger, or more open than its normal size or state. This expansion can apply to various body parts, such as blood vessels, pupils, or airways. It's often a physiological response to stimuli, medications, or medical conditions. The degree of dilation can vary, ranging from a slight widening to a significant and noticeable increase in size. This term is crucial in medical observations and diagnoses, providing valuable information about the body's internal state. Outside of biology it can metaphorically express widening or expansion, often used to describe the scope or effect of something.
