Q

Serous Membranes

A

Double walled membrane.

Parietal- outer part
Visceral- part that covers the organs

Produces serous fluid, lines the closed body cavities.

Allows organs to move freely, prevents friction.

Pleural membrane, pericardial membrane, peritoneal membrane.

Q

Primary Epithelial Tissue Repair

A

Clean wound: new stratified squamous epithelial cells “push” upward toward surface of skin.

Large skin area: fluid escaping from damaged tissue will dry and seal wound, forming a scab; great or deep area may require skin grafts.

Deep tissue: edges of wound sewn together with sutures.
