When bacteria in your body how does it defends itself?

Answer 1

the bacteria attaches itself to healthy cell and slowly destroys them when they multiply. this is also true for viruses. when you feel bad or sore throat, that is simply the bacteria/virus being fought off.

Answer 2

Leukocytes (white blood cells) can and will destroy bacteria, but if there are too many they (bacteria) may cause infection. It is best to aid the body in avoiding bacterial infection by taking adequate preventative measures, such as appropriate washing of the hands. The integumentary system also serves as a barrier against bacterial infection. Aside from the physical barrier of the skin, the integumentary system also includes sebaceous glands, which produce sebum, a natural antibacterial agent. The eyes preventative membranes, as well as glands to produce tears, which contain further antibacterial agents. The nose or throat you can sneeze or cough out potential invaders. Air inhaled through the nose passes first through nostril hairs, which act as filters. Then it is retained in the sinal cavities, where it undergoes further filtration, and finally invaders may be trapped in mucus lining the trachea. The mouth contains saliva, which can kill invasive bacteria. The stomach contains gastric juices, which are very acidic, and serve as a further line of defense. The body has fail-safes against practically every possibility of incursion.

Answer 3

The body defends against bacteria by using the immune system, which includes white blood cells that can detect and attack harmful bacteria. Additionally, the body can create antibodies that can specifically target and neutralize bacteria. In some cases, the body may also use inflammation to stop bacteria from spreading.
