This essay focuses on the digestive system of ruminant animals like cattle‚ sheep‚ and goats. Ruminant animals are hoofed mammals that have a digestive system which enables them to utilize energy from fibrous plant material better than other herbivores. Unlike monogastric animals such as pigs and poultry‚ the digestive system or ruminants is designed to ferment feedstuffs and provide precursors for energy for the animal to use.

1. Our digestive system provides the body a means to transfer nutrition from the external environment into the cellular level in order to sustain life. Salivary glands‚ controlled by the autonomic nervous system‚ are located in the oral cavity. Its main role is to secrete saliva in the oral cavity. There are three pairs of salivary glands. Parotoid savary gland lies under the skin on each side of the mandible. These glands secrete amylase‚ an enzyme that breaks down starches. The parotoid duct implies

The Pancreas (M1) Structure of the pancreas The pancreas is an elongated digestive organ that lies next to the small intestine.
