1. Boundaries - Cover surfaces

2. Support- Lines body cavities

3. Cushioning- Forms protective sheets around organs

4. Lubrication- Secretion, absorption and lubrication

1. Epithelial membranes

2. Connective tissue membranes

1. Cutaneous membrane

2. Mucous membranes

3. Serous membranes

4. Synovial membrane

The skin; composed of epidermal and dermal layers

Membrane that secretes mucus that lubricates the surface of organs and keeps them moist.

thin layer of tissue that covers internal body cavities and secretes a fluid that keeps the membrane moist; reduces friction

Pleural, pericardial and peritoneal

It is a membranous sac around the lung cavity

It is a membranous sac around the heart

It is a serous membrane lining the interior of the abdominal cavity and covering the surfaces of the abdominal cavity.

The lining of a joint that secretes synovial fluid into the joint space.

1. Parietal: lines a specific part of the ventral cavity

2. Visceral: lines the outside of the organ

Both layers secrete serous fluid
