| Question | Answer |
| Overall, the two intrinsic defense systems act: | Independently, but cooperatively to facilitate body defense |
| The two Body Defense systems are called: | NONSPECIFIC & SPECIFIC (ADAPTIVE) |
| FIRST LINE OF DEFENSE: | SKIN (& IT'S PRODUCTS) and MUCOUS MEMBRANES (& PRODUCTS) |
| SKIN & MUCOUS MEMBRANES HELP BY: | blocking the entrance of micro-organisms |
| EPIDERMIS IS HEAVILY: | keratinized |
| Keratin help to provide a: | physical barrier- water proof |
| Keratin is resistant to: | toxins, bacterial enzymes and weak acids |
| Intact mucosae provide physical (mechanical) barriers as they: | cover and line body organs |
| Mucous membranes produce: | defensive chemicals |
| The acidity of secretions produced by some membranes helps: | inhibit bacterial growth |
| Examples of mucous membranes are: | vaginal membranes, gastric lining, |
| Sebum is: | ear wax |
| Sebum contrains chemicals: | toxic to bacteria |
| Stomach mucosa produces: 2 | HCI and protein-digesting enzymes |
| HCI is | hydro chloric acid |
| Saliva & lacrimal fluid contain: | lysozyme |
| lysozyme is: | an enzyme that destroys bacteria |
| lacrimal fluid is found: | tears |
| Mucus feels: | sticky |
| Mucus traps micro-organisms trying to enter:2 | the respiratory and digestive systems |
| Some mucous membranes have special structures, such as: | hair or cilia, to repel/trap invaders |
| Releasing chemicals for communication is called: | Chemo tactic |
| Anything that prevokes a response is: | Antigen |
| Paracrine | chemical that acts locally |
| Hormones | travel globally |
| Acquired Immunity: | from having the disease OR from vacine |
| Passive Immunity: | from Mom-not long lasting |
| Mucus | the fluid product |
| Mucous | the producer |
| PPI | protein pump inhibitor |
