MICROBIAL ENEMY CLASS
* Bodyland aliens ( bacteria , virus . fungi . parasites ) criminals ( bacteria , virus , fungi , parasites )
our defence strategy system has three lines of defence 1. natural skin barrier,mucous lining,tears and gastric acid second line of defence is phagocytosis,complement,interferon,inflammation and fever.in this defence there is no stoppage but killing and removing the enemy by defenzive strategy third line of defence is lymphocytes and antibodies third line of defence comprises of police and soilders who are protecting our human body. they have specific badges called markers also called immune cell markers.
bad persons always carry guns and bombs with them these are equivalent to the toxins released by the bacteria.
A medieval castle would be a good analogy of the innate immune system. The high castle walls and the moat around the castle are designed to keep almost everything out. They act like the body's skin, mucous, and stomach acid. In the moat, we have alligators, which like the macrophages in the body, will basically eat anything. In our castle analogy, the adaptive immune system would include archers, spear-throwers, cannoneers, and swordsmen. They each use different tools and defend against those invaders for which they are best designed. They remember previous battles and can improve the speed and efficiency in which they defend the castle. Working together: The innate system is the first line of defense. If the invader is stopped by the innate system, no disease will occur. If, however, the invader cannot be stopped by the innate system, the adaptive system is activated. If the adaptive system is successful, the body will recover. The adaptive system will also retain memory of the invader. So, if a second exposure to the invader occurs, the adaptive system will mount a greater and faster response, usually preventing disease. If neither the innate or adaptive systems are effective, death can occur.
- clostridium – (kloster=spindle)
- bacillus– (rod shaped=bacilli)
- hemophilus influenzae – (hemo(blood)+philus(loving))
- diplo(pair)+ cocci(round) – diplococcus
- vibrio – curved rods(vibrio-vibrate)
- strepto(twisted or coiled) + coccus(round)–streptococcus molli(soft)+cutis(skin)= mollicutes
- staphylococcus - staphy(bunch of grapes) + coccus(round)
- corynebacterium diptheria – coryne(club) + diphteria(leather)
