Physiological functions of food
a. Energy giving. This group includes foods rich in carbohydrate, fats and proteins. ...
b. Body Building: The foods we eat become us. Thus one of the most important functions of food is that of building the body.

In the food vacuole secretes digestive juices inside the vacuole that help in its digestion. The amoeba secretes waste out of its body by spurting out the waste through the nucleus. Nutrition in grass eating animals. In grass eating animals, Buffaloes and other animals swallow grass and store it in a separate part of the stomach called Rumen.
Chyme released from the stomach enters the small intestine, which is the primary digestive organ in the body. Not only is this where most digestion occurs, it is also where practically all absorption occurs. The longest part of the alimentary canal, the small intestine is about 3.05 meters (10 feet) long in a living person (but about twice as long in a cadaver due to the loss of muscle tone). Since this makes it about five times longer than the large intestine, you might wonder why it is called “small.” In fact, its name derives from its relatively smaller diameter of only about 2.54 cm (1 in), compared with 7.62 cm (3 in) for the large intestine. As we’ll see shortly, in addition to its length, the folds and projections of the lining of the small intestine work to give it an enormous surface area, which is approximately 200 m2, more than 100 times the surface area of your skin. This large surface area is necessary for complex processes of digestion and absorption that occur within it.
