Answers
Explanation:
1. The fibroblast is one of the most abundant cell types present in the stroma. It has a variety of functions and composes the basic framework for tissue and organs. Under homeostasis, this cell is responsible for maintaining the extracellular matrix.
2. Transient cells are leukocytes that circulated in the bloodstream and migrate into connective tissue at sites of an immune response. These include neutrophils, eosinophils, basophils, lymphocytes and monocytes.
3. The process of collagen synthesis occurs mainly in the cells of fibroblasts which are specialized cells with the main function of synthesizing collagen and stroma. Collagen synthesis occurs both intracellulary and extracellulary.
4. The ground substance of extracellular matrix is an amorphous getation material.
Ground substance is primarily composed of water and large organic molecules, such as glycosaminoglycans, proteoglycans and glycoproteins.
5. Loose connective tissue consist of protein fibres packed with spaces whereas dense connective tissue consist of tightly packed protein fibres.
