The main duty of this gastric juice is
to change the albuminoids into a form
in which they can be absorbed and
used by the animal
Cattle and sheep have a very large
stomach. which is divided into four
parts. Animals of this kind are called
ruminants. When the food is swallow
ed it passes into the first stomach
which serves the purpose Of a store

continues, and the water which the
animal drinks softens the food to a

After leaving the stomach the par

upon by three huids-the bile. pan

chief use Of the bile is to digest the
fats, making them into a sort Of
