Which structure lies between the iris and the retina and contains many blood vessels?

Explanation:
The structure that really provides the blood supply to the retina is the vascular layer of the eye, the choroid coat. It sits just behind the retina and contains a dense network of arteries and veins, delivering oxygen and nutrients to the outer retinal layers and helping remove waste. Its rich blood supply and proximity to the retina explain why it’s described as containing many blood vessels. In contrast, the cornea is transparent and avascular, the iris is a pigmented diaphragm with limited vessels, and the ciliary body, while vascular, is mainly involved in accommodation and aqueous humor production rather than serving as the primary retinal blood source. So the choroid coat best fits the description.
