saw5 [17]
They share similarities in their tissue and cartilage. Both humans and chickens have epithelial tissue, muscle tissue and connective tissues; as well as cartilage to support the joints between bones. The bone structure is similar as well. Both animals have a humerus, which connects the shoulder and radius. Unlike humans, chickens can't move their metacarpals.

Then it goes into small intestine, then the large intestine where it is determined to be a solid, liquid, or gas and the liquid is normally drained out causing it to be solid, Then it is eventually stored in the rectum and released through the anus.
