Describe to messes of which pathogen is maybe transmitted between hosts.
Bodily fluids and vectors such as mosquitos
Two ways which passages can enter through a portal and gain access to infect the human body.
Eyes and nose. Nose hair and eyelashes or hair follicles which stop pathogens from entering the body. Mucus and tears are liquids which help stop passages from entering further.
What is the similarities and differences between natural and artificial immunity
Similarities provide protection from pathogens. difference is passive short-term provided by an outside source or active long-term protection created by own body.
