Rick sends Morty to Anatomy Park so that he can find Doctor Bloom and help save Reuben's life from within his body. As Morty navigates through Anatomy Park, he finds body parts, such as the spleen and pancreas, along with red blood cells. These bodily components are illustrated in an excellent manner.
Beakman answers quick questions about blood, veins, and their functions. They demonstrate this by having Josie dress as a "cell" and she goes to a restaurant where "blood" is the waiter that offers her food first and then takes away her waste to the kidneys and lungs. Then they have a germ come in and try to get close to the "cell" and "blood" comes in a cap and gets rid of the germ.
