Quite an unknown organ, this lymphatic system with all the branches and nodes and the liquid. This time, our friends, the red corpuscles, don't accompany us, because they don't belong here. But Young Peter and his friends undergo another adventure on their trip through this system, whose task it is to transport nutrition in the body.
