Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The collagen fibers shift their type from type three collagen to type one collagen
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Type III collagen fibrils are thinner than type I fibrils [19] and are present in high concentrations in skin, blood vessels and other tissues with large proportions of elastic fibers. During the healing process in tendon, a randomly-oriented initial network of mostly type III collagen is formed at the wound site [20].

Detailed explanation-2: -Nearly 28 types of collagen have been identified, but collagen type I is the most common in skin, bone, teeth, tendon, ligaments, vascular ligature, and organs. Collagen type II is present in the cartilages. For collagen type III, the skin, muscle, and blood vessels are the most common sources of this protein.

Detailed explanation-3: -Early in normal wound healing, type III collagen predominates but is later replaced by type I collagen.

Detailed explanation-4: -Collagen I-found in bones, tendons, organs. Collagen III-found mainly in reticular fibres ( fine fibrous connective tissue occurring in networks to make up the supporting tissue of many organs).
