Cells also must make the products your body needs, such as sweat, saliva, enzymes, hormones, and antibodies.Chapter 1, "An Owner's Guide to the CellChapter 2, "Cells 101: Business BasicsChapter 3, "On the Job: Cellular Specialties,"Chapters 4, "Cellular Reproduction: Multiplication by Division,"Chapter 5, Cell Aging and Death,"
