Body membranes Definition of membrane Types Cutaneous membrane (skin) Serous membrane Parietal - lines cavity Visceral - covers organs Pleura - in lung Peritoneum - in abdomen Mucous membrane Connective tissue membrane synovial Definition of membrane Types Cutaneous membrane (skin) Serous membrane Parietal - lines cavity Visceral - covers organs Pleura - in lung Peritoneum - in abdomen Mucous membrane Connective tissue membrane synovial

33. How an injury heals 1. capillaries constrict 2. Platelets stick to edges and clot forms – seal off injury 3. scab forms – protect injury 4. debris is cleaned out – macrophages eat away damaged tissue to leave room for repair 1. capillaries constrict 2. Platelets stick to edges and clot forms – seal off injury 3. scab forms – protect injury 4. debris is cleaned out – macrophages eat away damaged tissue to leave room for repair

34. 5. Organization of tissue parts – granulation occurs (a type of intermediate tissue) 6. Macrophages digest & remove original clot 7. Surface epithelium regenerates – scab usually falls off at this time End result: Healed injury! 5. Organization of tissue parts – granulation occurs (a type of intermediate tissue) 6.
