Connective Tissue
3 basic components of connective tissue
-CELLS
-PROTEIN FIBERS

Fixed Machrophages
(irregular shaped Cells)
(Part of cells of connective tissue)
Fixed Machrophages
derived from monocytes (White Blood Cells)
secrete heparin in inhibit blood clotting
secrete histamine to dilate blood vessels
mast cells

plasma cells
Plasma Cells
produce antibodies
Type of wandering cell
free macrophages
Collagen: strong, (tendons and ligaments)
Reticular: thinner, form branching interwoven framework (lymph nodes, spleen, and liver)
Elastic: stretch and recoil easily (skin, arteries, and lungs)
Protein fibers: 3 types
Protein fibers: 3 types
Collagen: strong, (tendons and ligaments)

2/3 Protein Fibers
-Thin Fibers
- form branching interwoven framework (lymph nodes, spleen, and liver)
-
Reticular fiber
3/3 Protein Fibet

(skin, arteries, and lungs)
elastic fiber
protein fibers + ground substance =
extracellular matrix.
extracellular matrix is made up of what
he protein fibers + ground substance
