Document Summary
Body membranes: cover surface, line body cavities, and form protecting lubricating layers around organs. Divided into two major groups: epithelial membranes: cutaneous, mucous and serous membranes, connective tissue membranes: represented by synovial membranes. Epithelial membranes: also called covering and lining membranes, do contain epithelial sheet, it is always combined with an underlying layer of connective tissue. Cutaneous membrane: is your skin, superficial epidermis is composed of a keratinizing stratified squamous epithelium, underlying dermis is most dense connective tissue, exposed to air and is a dry membrane. Chapter 12: the lymphatic system and body defences. Part 1: the lymphatic system: consists of two semi-independent parts, 1. A meandering network of lymphatic vessels: 2. Homeostatic imbalance: lymph nodes can become secondary cancer sites, cancer infiltrated lymph nodes are swollen but not painful and helps to distinguish cancerous lymph nodes from those infected.
