Small Intestine
Digestive organ where most chemical digestion and absorption of food takes place
Involuntary Muscles
(Blank) are muscles, such as the heart, that automatically do their jobs without you needing to think about it. These muscles run all the Important jobs inside the body, such as breathing and digestion.
