Epithelial Tissue protects the body by covering
internal and external surfaces, and produces
secretions
 Skin
 covers the outside of the body
 lines the inside of the body
 Membrane
 two thin layers of tissue that join together
 cells may secrete a fluid

Connective tissue supports and connects
organs and tissue
 Adipose type of connective tissue that stores fat cells
 Cartilage firm, flexible support of the embryonic skeleton
and part of the adult skeleton
 Tendons white bands of connective tissue attaching
skeletal muscle to bone
 Ligaments strong, flexible bands of connective tissue that
hold bones firmly together at the joints

Muscle tissue contracts and moves a body
part
 Cardiac
 striated, involuntary
 contracts the heart
 Skeletal
 striated, voluntary
 attached to the skeleton
 Smooth
 nonstriated, involuntary
 provides movement in various body systems
