Mucous membranes are coated with the secretions of mucous glands. They line most of the digestive and respiratory tracts and portions of the urinary and reproductive tracts. Line passageways that communicate with exterior
Line ventral body cavities (pleural, peritoneum, pericardium); transparent, thin, prevents friction
The skin; covers the outer surface of the body. In contrast to serous or mucous membranes, the cutaneous membrane is thick, relatively waterproof, and usually dry.
Line join cavities (articulations) and produces the synovial fluid within the joint. the synovial fluid lubricates the cartilages in the joint, distributes oxygen and nutrients, and cushions shocks at the joint.
1) Thin, transparent- simple squamous epithelium + areolar
2) Attached to the body wall & organs they cover - ventral body cavity
3) Minimizes friction
* Lines open body cavities that are closed to the exterior of the body
* Serous layers separated by serous fluids
THERE IS A VISCERAL LAYER AND PARIETAL LAYER
