The difference is important in mechanics. Dilation refers to a uniform enlargement or stretch whereas dilatation refers to general enlargement
RMB Ex. A human pupil dilates and a cat pupil dilatates
Pupils don't dilate from light, the constrict. They dilate in the dark, to take in more light, and constrict in the light so your eyes don't get damaged. Hallucinogenics, stimulants and alcohol and make your pupils dilate and opiates and diazepam can make them constrict. Im not sure what that's called though..
An example of an intrinsic reflex is the pupillary reflex, in which the pupils of the eye constrict when exposed to bright light and dilate in response to darkness. This reflex helps regulate the amount of light entering the eye to optimize vision.
Arterioles are the major determinant of peripheral resistance in the cardiovascular system. Their small diameter and ability to constrict or dilate play a key role in regulating blood flow and pressure in different parts of the body.
The drops the ophthalmologist put in my eyes made my pupils dilate.
When light is shone into one eye, the pupillary light reflex causes both pupils to constrict simultaneously due to the connection between the two eyes. This is known as a consensual response and helps to regulate the amount of light entering both eyes.

Nothing, blood vessels are nothing because they wont harm you or anything like that.
No, oxygen does not dilate blood vessels. In fact, oxygen has a vasoconstrictive effect, which means it causes blood vessels to constrict or narrow. This helps regulate blood flow and pressure in the body.
The term Elastic Arteries usually refers to the ability of blood vessels to dilate and constrict freely.
