AP: CHAPTER 43: IMMUNE SYSTEM 1. List the two lines of nonspecific defense mechanisms with examples of each. • External defense‚ which includes the skin and mucous membranes in the body. • Internal defense which includes phagocytic cells and antimicrobial proteins. 2. What is meant by specific defense? Defense mechanisms are said to be specific because depending on which one they focus on one specific part of the body or a specific type of pathogen. 3. Give examples of “barrier defense

Overview: Life at the Edge The plasma membrane separates the living cell from its nonliving surroundings. This thin barrier‚ 8 nm thick‚ controls traffic into and out of the cell. Like all biological membranes‚ the plasma membrane is selectively permeable‚ allowing some substances to cross more easily than others. Concept 7.1 Cellular membranes are fluid mosaics of lipids and proteins The main macromolecules in membranes are lipids and proteins‚ but carbohydrates are also important. The
