When evil bacteria enters the human body , different types of Macrophages start attacking them and try to eat as much bacteria as possible to prevent , decrease or eliminate the infection .
Unfortunately , it’s a hard process because Bacterial cell membrane carry a -VE charge & also our Phages carry a -VE one
so .. there is a kind of repulsion force between our immune cells and the evil bacteria :ermm:
The good thing is , Our immune system prepares other mechanisms to help in this repulsion situation ..
How :whistle: ?
Firstly , Immunoglobulins ( Also known as antibodies ) & The complement system are degraded into certain small fragments
these fragments get attached on the surface of the bacteria ..
Luckily , Antibody’s and complement’s fragments carry +VE charges , so the neutralize the bacteria
Now Evil bacteria are cooked up & the repulsion between them & our immune system is over .. so , macrophages can attack and eat the bacteria smoothly
[tip] The process of neutralizing the bacterial -VE charges on the bacteria to make it fixed and easily phagocytosed by macrophages is called ” Opsonization “ [/tip]
