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 in the body
Adipose- type of connective tissue that stores fat cells. Cushions,
supports and insulates the body
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
involuntary
contracts the heart muscle to pump blood
Skeletal
voluntary
attached to the movable parts of the skeleton
Smooth
involuntary
provides movement in various body systems (digestive, genitourinary,
respiratory tract, blood and lymphatic vessels
