Overview of immune system

Let's say a foreign object enters the body. I'm trying to compose an overview of the immune system response.

First, the innate immune system kicks in. Neutrophils first and then macrophages bind to the object. Macrophages (and not neutrophils) "show" the object to T lymphocytes cells. The T cells decide to activate the immune system. If the immune response is necessary, T-helper cells stimulate B cells to initiate humoral immunity, which involves the conversion of B cells into plasma cells to secrete antibodies.

If that same foreign object comes in again, and antibodies recognize it, the B cells can kick into gear immediately in the future.

Can anyone fill in gaps here and/or fix any part of it?

Way more than you need to know for the MCAT, but I watched this full lecture and have been acing immunology on the MCAT: http://www.youtube.com/watch?v=5Ut_sVgQ0dY&list=PLAF657E78412A7D81&index=1

Wow, that lecture was really good, although very detailed...

It's a lecture from Ross School of Medicine in the Caribbean, but by far one of the clearest lectures I've seen and now the Kaplan MCAT book makes way more sense.

Definitely don't pay too much attention to the details, but pay attention to big picture and especially the summary at the end.
