The immune system protects the body against infection and disease. It is a complex and integrated system of cells, tissues, and organs that have specialized roles in defending against foreign substances and pathogenic microorganisms, including bacteria, viruses, and fungi.
The shmoo (plural: shmoon, also shmoos) is a fictional cartoon creature created by Al Capp (1909â79); the character first appeared in its classic comic strip Li'l Abner on August 31, 1948.
A shmoo is shaped like a plump bowling pin with stubby legs. 1  It has smooth skin, eyebrows and sparse whiskersâbut no arms, nose or ears. Its feet are short and round but dextrous, as the shmoo's comic book adventures make clear. It has a rich gamut of facial expressions and often expresses love by exuding hearts over its head.
