Answer:
1) The villi of the small intestine project into the intestinal cavity, greatly increasing the surface area for food absorption and adding digestive secretions.
2) A ruminant is a mammal with hooves and a complicated system of stomach compartments whose digestion works by chewing partly digested food a second time in order to soften it. Cows, moose, giraffes, and goats are all ruminants.
3) Oesophagus is also called the food pipe. It runs along the neck and the chest. The food from mouth after swallowing passes into oesophagus and is pushed down to stomach
