sympathetic stimulation causes the dilator muscle to contract and sphincter muscle to relax, as a result expanding the pupil.
Dilated pupils can indicate attraction or interest, as they can widen when someone is excited or engaged. However, it's important to consider other factors such as lighting, drugs or medical conditions that can also cause pupil dilation.
The release of inflammatory mediators such as histamine, prostaglandins, and nitric oxide causes arterioles in the damaged area to dilate. This dilation increases blood flow to the damaged tissues, bringing in immune cells and nutrients to aid in the healing process.
An increase in heat causes blood vessels to dilate, which increases blood flow in the body.
