I don't understand how antigens can mutate can anyone help?

Muddiest Point

My muddiest point is for nonspecific defenses, when the second line of defense comes into action are there specific defenses? For example, for first line defense there are things like the skin, cilia and tears, saliva, etc. What are examples of second line? If there are any.

Thanks

Today in class, we learned how to read a certain type of graph. Also we learned exactly how a T cell kills an infected cell and the process of it.

We also learned a little about APC

APC means Antigen Presenting cell.

Our homework is in the unit packet, pages 32, and pages 37-42 also to read 35.4

The next scribe will be SARAH
