The Lymphatic and Immune Systems

Let’s start with the lymphatic system first.

So the lymphatic system is both the transport system and barracks of the immune system. It recycles lost fluids form the cardiovascular system, transports pathogens to the lymph nodes where they can be destroyed, store and mature some types of WBC and absorbs glycerol and fatty acids from food.

It consists of lymph capillaries, vessels, trunks and ducts containing lymphatic fluid and lymph nodes.


The immune system…

Ok.., its function is to ignore self-antigens and respond to non-self antigens. It is divided to innate and adaptive immunity.

Innate immunity is nonspecific, has no memory and cannot improve performance with experience. Adaptive immunity, on the other hand, is exactly the opposite of immunity. (I Suppose)

So what else? The immune system uses different types of cells to fight pathogens. There are also barriers that can be either physical or chemical (like the skin and tears).

I think illustrations, graph and other visual aids will help in teaching this lesson.
