In fact all invasors shall be identified by the body defenders as dangerous invaders, except those ones that are part of the body's normal living microorganisms like the gut flora for instance. They are lactobacillus found in yougurts.
If they are more aggresive, a lot of defenders are sent to the battle field to fight them.
There are no "friendly" invaders when the subject are microorganisms, except those ones mentioned above.
immune system
its killer T cells
The body's internal defenses include the immune system, which comprises various cells and proteins that work together to identify and eliminate pathogens like bacteria and viruses. Key components include white blood cells, antibodies, and the complement system, which help detect and destroy invaders. Additionally, the body has mechanisms such as inflammation and fever that enhance the immune response. Together, these defenses maintain health and protect against infections.
axons neurons , cells help protect the bodys defense system against infection ..auto-immune defiency ...also oxygen
The body's main defense barrier against microorganisms is the immune system. This system includes physical barriers like the skin and mucous membranes, as well as specialized cells and proteins that identify and destroy pathogens to prevent infections. Additionally, the body has inflammatory responses that help to contain and eliminate invading microorganisms.
yes it can because it is a bacteria, the bodys immune system automatically starts producing more white cells to fight off the bacteria
Cardiovascular
Circulatory system
yes
I believe the bodies transportion system is the cardiovascular system :)
Respiratory
When a bacterial infection occurs, the body's immune system responds by recognizing the bacteria as foreign invaders. The immune system then produces white blood cells to attack and destroy the bacteria. This process can also involve inflammation to help contain and eliminate the infection.
