The nervous system is compared to airmail delivery because it is fast, allowing rapid communication through electrical impulses. In contrast, the endocrine system is compared to the Pony Express because it is slower, relying on hormones that travel through the bloodstream to communicate between different parts of the body.
The nervous system is compared to an airmail delivery system because it transmits information quickly, like airmail travels fast over long distances.

No, T cells do not express MHC II. MHC II molecules are primarily found on antigen-presenting cells, such as dendritic cells, macrophages, and B cells, and are involved in presenting antigens to T cells for immune responses.
