PURDUE BIOL 203: LAB 4
(CONNECTIVE TISSUE AND THE
INTEGUMENTARY SYSTEM) EXAM
100% SOLVED
, Function of connective tissue (8) - ANSWER1. Binds structures together
2. Supports and protects
3. Serves as a framework
4. Fills up spaces
5. Stores fat
6. Generates blood cells
7. Protects against infections
8. Helps repair tissue damage
What are the 2 main things that connective tissue consists of? - ANSWERcells and
matrix (which has fibers and ground substance)
Ground substance of matrix - ANSWERgel-like material composed of special protein
molecules to which are attached large amounts of carbohydrates called proteoglycans;
present in all tissues and organs and they bind water (maintain tissue hydration)
5 Different Cell Types in Connective Tissue - ANSWERfibroblasts, macrophages, mast
cells, white blood cells, specialized cells
Collagenous Fibers - ANSWERthick white fibers that form strong structures such as
ligaments and reinforce connective tissue; networks of thin collagen fibers (reticular
fibers) form supportive networks in various organs
Elastic Fibers - ANSWERyellow fibers composed mainly of the protein elastin, but also
contain fibrillin; thinner than collagen fibers and they are found in structures subject to
stretch (b/w vertebrae)
Fibroblasts - ANSWERwidely distributed, large cells; secrete proteins (collagen, elastin)
that become fibers
Macrophages - ANSWERmotile phagocytic cells; clear foreign particles from tissue; part
of the immune system and important in inflammation
Mast Cells - ANSWERLarge cells packed with granules, usually located near blood
vessels; release substances that help prevent blood clotting and promote the
inflammatory response
White Blood Cells - ANSWERmove into connective tissue during the inflammatory
response (e.g phagocytic neutrophils)
