Hi! It's Eunice C! I had some problems logging in but I'm in now!
I thought this unit was a bit confusing learning about all the bacteria's, viruses, the cells defenses, immunity, etc... BUT, the most difficult part for me was understanding the nonspecific and specific defense against diseases. How do they differ?
Non Specific Defenses are ones like barriers that target foreign cells, while specific defenses target specific antigens in the body. Hope this kinda helps.
