Everyone. Let's take a look at this question together in connective tissues. Which of the following cell types plays an important role in wound healing by synthesizing extracellular matrix proteins. Is it answer choice. A macrophages. Answer choice B monocytes, answer choice C fibroblasts or answer choice D lymphocytes. Let's work this problem out together to try to figure out which of the following cell types plays an important role in wound healing by synthesizing extracellular matrix proteins. Well, when it comes to connective tissues and the cell types that are found in connective tissues, we know that the cell type that is most common is the fibro blast. And we note that those fibroblasts migrate to the site of injury during that inflammatory phase of wound healing and synthesize those extracellular matrix proteins such as collagen and elastin to support that migration and tissue repair, which means that the cell type that plays an important role in wound healing by synthesizing those extracellular matrix proteins are the fibroblasts. So answer choice C fibroblasts is the correct answer. And we note that answer choice A B and D are all incorrect since macrophages monocytes and lymphocytes do not synthesize those extracellular matrix proteins during wound healing. And the only cell type that does are the fibroblasts, which is answer choice C I hope you found this video to be helpful. Thank you and goodbye.
