Question

what will happen if harmful substances enter yours body? how do you feel​

Answer 1

Answer:

If harmful substances enter your body it will have many side effects.Harmful germs are usually calles pathogens.Actually the thing what happens here is these pathogens enter your body either through air or water as we humans have a nose and a mouth which is the only way these substances can enter.So,after they enter,our body produces some good bacteria's called Probiotics which help in fighting the pathogens.When this takes place we feel a little ill or sick.To help fight the pathogens we from our side take in Antibiotics which help the good bacteria's.

Hope it helps..!!
