This is a spread of connective tissue stained with H&E and Azure. Seen here are some thin elastin fibers and granulitic macrophages. The macrophages help rid the body of worn out cells and debris, and aid in immune response. Although they are usually angels of the immune system, they can sometimes be corrupted by immune system diseases and used for evil. This happens in some cancers, HIV, atherosclerosis, and tuberculosis. It is snowing out so I drew the angel singing Christmas carols. Wikipedia, however, does not say if there is any relationship between macrophages and musical talent. I guess it is possible.
Lovely angel!
