what is the function of the digestive system in animals?
604218
The digestive system consists of the parts of the body involved in chewing and digesting feed. This system also moves the digested feed through the animal's body and absorbs the products of digestion. Different species of animals are better able to digest certain types of feeds than others.

The stomach's main function is digestion. It does this by: Storing the food we eat. Breaking down the food into a liquidy mixture called chyme.

The digestive system ingests and digests food, absorbs released nutrients, and excretes food components that are indigestible. The six activities involved in this process are ingestion, motility, mechanical digestion, chemical digestion, absorption, and defecation.

The digestive system has three main functions. They are digestion, absorption, and elimination.

The digestive system is the organ system that breaks food down into small molecules that are absorbed into the bloodstream. Digestion is helped by enzymes, which are biological catalysts.

The bowel is considered to be a part of the digestive or gastrointestinal system. It is designed to help the body absorb nutrients and fluids from the foods we eat and drink. After taking out everything the body needs, the bowel then expels the leftover waste.

Human digestive system. The human digestive system is a complex series of organs and glands that processes food. In order to use the food we eat as energy, our body has to break the food down into smaller molecules that it can process; it also has to excrete (or get rid of) waste.

It digest food in two ways, mechanically and chemically. Both help in the process of turning food into nutrients. The digestive system also eliminates solid food waste. The major organs of the digestive system include the mouth, esophagus, stomach, and small and large intestines.

The digestive system has three main functions: digestion of food, absorption of nutrients, and elimination of solid food waste. Digestion is the process of breaking down food into components the body can absorb.

Interacting with Other Systems The digestive system works very closely with the circulatory system to get the absorbed nutrients distributed through your body. The circulatory system also carries chemical signals from your endocrine system that control the speed of digestion.

The digestive system is made up of a group of organs that work together to break down food. During digestion larger molecules are broken down into smaller ones. These molecules are transported around our body to be used for energy, growth and repair.

Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach they have four. Of the four compartments the rumen is the largest section and the main digestive centre.

The cells of most animals are organized into higher levels of structure, including, tissue, organs, and organs systems. What are four major functions of animals? Some major functions of animals are obtaining food and oxygen, keeping internal conditions stable, moving, and reproducing.

Functions. Their function is to increase the surface area of the small intestinal wall for absorption of the digested food. These projections absorb the protein molecules and help in the transfer of the proteins to all cells and tissues.

Animals have evolved different types of digestive systems to aid in the digestion of the different foods they consume. The simplest example is that of a gastrovascular cavity and is found in organisms with only one opening for digestion.

Bile. The primary digestive function of bile is to aid in the dispersion and digestion of fat in the lumen of the small intestine. Bile is formed initially in the hepatocyte (liver cell), and the rate of formation is dependent primarily on the rate at which bile acids are secreted into the bile channels, or canaliculi.

Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair.
