2. Epithelial Tissues Excercise 8
Tissue A aggregate of with similar structure and
function.
Histology - The science that studies tissues.

3. Epithelial Tissue – Groups of cells that are Protective Absorptive
Secretory
Transport
Excretory
Closely attached to each other to form tight sheets lacking in extracellular matrix and vascularization.
Cells rest on basal lamina which in turn rests on connective tissue.
Free on one end (Apical Surface).

12. Connective Tissue
Perform binding, support ,transport and nutritive functions Connective tissue has three types of fibers Collagenous (white) Fibers –Relatively large, thick bundels. Reticular Fibers - Minute network of very fine threads stains well so it looks black. Elastic (yellow) Fiber- contains elastin protein. Found in organs and tissues that must yield to changes in shape.

13. Connective Tissue Matrix
Extra cellular fluid consisting of fibers, fluids, ground substance and or inorganic compounds form the connective tissue matrix.
Cell types seen in matrix are fibroblasts, adipose cells, mast cells, plasma cells, macrophages and other types of blood cells.
Ground Substance An amorphous solution or gel around the cells and fibers
