Root Explanation

Chorioallantoic is formed from "chorion" (from Greek "chōrion", meaning membrane) and "allantois" (from Greek "allantois", meaning sausage or sausage-like structure). The word refers to a specific type of membrane that combines the chorion and allantois in the development of certain embryos, particularly in reptiles and birds.

Memory Tip

Think of 'membrane' ('chorion') and a 'sausage-like structure' ('allantois') coming together to form a protective layer around an embryo.
