The vitreous contains predominantly which type of collagen?

Explanation:
Vitreous contains predominantly Type II collagen. This type forms the main fibrillar network that, together with proteoglycans, creates the gel-like, transparent matrix of the vitreous. Type I collagen is mainly in sclera and bone, providing strength; Type III is more abundant in skin and blood vessels and during early wound healing; Type IV is a basement membrane component. So the collagen most responsible for the vitreous structure and transparency is Type II.
