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

Mucous Membranes:
•Lines surfaces & spaces that lead to the outside of the body
•Line respiratory , digestive, reproductive & urinary systems
Serous Membranes:
• Double walled membrane that produces a watery fluid &
lines closed body cavities (fluid is called serous fluid)
• Parietal Membrane: outer part that lines the cavity
•Visceral Membrane: covers the organs within the cavity

Examples of membranes
Pleural: lines thoracic cavity & protects lungs
Pericardial: lines heart cavity& protects heart
Peritoneal: lines abdominal cavity & protects abdominal
organs

Synovial Membranes:
•Lines joint cavities
•Secretes synovial fluid which prevents friction
inside the joint cavity

Epithelial tissues
Squamous
Cuboidal
Columnar
Line heart, blood
& lymphatic vessels
Line kidney, ovaries
& some secretory
glands
Have cilia, cover
digestive & parts
of respiratory tract

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
