Tissue
Sheet of cells that cover the body surface
Epithelial tissue
4 major types of tissue
Epithelial
Connective
Muscle
Nervous
Found throughout the body
Main glandular tissue
Cells tightly packed together
Epithelial
Functions: Protection Absorption Filtration Excretion Secretion Sensory reception
Epithelial
Not vascular
Attached to underlying connective tissue by no cellular no living basement membrane
Epithelial
6 types of epithelial
Simple squamous Simple cuboidal Simple columnar Stratified squamous Pseudostratified Transitional epithelium
Most abundant tissue
Bonds structures together
Vascular
Functions: support protection framework fills space stores fat produce blood cells helps repair tissue
Connective tissue
3 common types of connective tissue
Mast cells
Macrophages
Fibroblasts
Eat or destroy, through the process of phagocytosis, anything that is foreign
Macrophage cells
White blood cells
Macrophage cells
Prevents blood clots
Mast cells
Produce fibers
Fibroblasts
Made of rote in collagen major structural protein in the body
Strong flexible but not elastic. White fibers
Bones ligament tendons
Collagenous fiber
Micro fibrils in protein elastin yellow fibers elastic
Respiratory and vocal cords
Elastic fibers
