Bacteria cause illness by disrupting the normal functions of our cells. For example, viruses often kill our cells in order to make more copies of themselves, so then symptoms of not having those cells start to pop up.
We can also become ill as a result of our immune system attacking bacteria/viruses. When we get rashes/bumps due to allergies, it's our immune system releasing antihistamines that cause swelling. Additionally, our body temperature will rise in order to help fight infection because certain immune cells function more efficiently at higher temperatures.
Tldr: Bacteria/viruses attack our cells to make us sick, and our immune system makes us feel sick when it fights bacteria/viruses

is getting runny nose because of common cold also a result of immune system? what's the point of it? it only makes you suffer

wanna add to this anon's post, often times bacteria arnt directly attacking cells, but just found a great place to live and as a byproduct of their metabolism excrete something toxic for our cells. I dont like the notion that bacteria are evil or predators, they just want to live and multiply, often at the expense of your cells

you mean an another organism's body that does evertything it can do to kill you? seems like a great place

Yes; the idea is to literally, physically flush out the bacteria. The mucus also has some anti-microbial properties.

You bodies release histamines, not antihistamines. Antihistamines are anti-allergy drugs.
Also, the main way bacteria make us sick is by releasing toxins that attack out tissues.

Ah yeah thanks. Dunno why I mistook that

I don't know enough about immune responses to say whether runny nose (or other symptoms of bacterial infection) is a result of the immune system. However, bacterial toxins usually interact with signalling proteins within cells, either inhibiting cell action or stimulating it. So, pertussis (Whooping cough), for example, is the result of a bacterial toxin stimulating activity in the respiratory epithelium which basically puts the cell into overdrive

I think /sci/ might have a lower avg iq than /lit/ and /his/ desu, the grammar, spelling, diction, rigor, lack of understanding of the most basic undergraduate subjects and laziness of posting all suggest low-midrange iq. very sad.

The runny nose is a result of your blood vessels dilating. They do that to let white blood cells through to the tissue. Unfortunately, this also causes more water to leave the capillaries and makes the tissue in that area swollen. And of course. contributes to a runny nose.
