Let’s first consider flatworms. One of the best known types of flatworms are tapeworms. As their name suggests, they look like long pieces of tape! All tapeworms are parasitesthat live in the digestive systems of other animals. Instead of finding their own nutrients, they absorb the pre-digested nutrients from their hosts directly through their bod...
Roundworms and annelids, like earthworms, are more advanced. They have a complete digestive system. Other invertebrates, such as insects, spiders and crabs also have a complete digestive system. A complete digestive system has a gastrointestinal tract(GI tract). This tract is a one-way system that starts at the mouth and ends at the anus. A GI trac...
Vertebrates are a group of animals that includes fish, amphibians, reptiles, mammals and birds. All vertebrates have a complete digestive system with a similar design. The system starts at the mouth. The mouth connects via a tube, called the esophagus, to the stomach. The stomach is usually an acidic environment where food is broken down into small...
Let’s start by looking at our own digestive system. Knowing how ours works will help you to understand the differences with other groups of mammals. Parts of the human digestive system include: Several other important organs participate in digestion but are not within the GI tract. One of these is your liver. Your liver produces bile. Bile is a che...
Ruminants are a groupof hooved herbivorous animals. This group includes cows, sheep, goats, deer, llamas, camels and giraffes. Ruminants have a very large stomach. It takes up ¾ of their abdominal cavity. Unlike ours, it has four compartments. Food travels through them in this order: 1. Rumen The rumen is the largest of the four chambers.This is wh...
Because stomachs are heavy muscular organs, birds have small ones to make flying easier. The term for the stomach of birds is proventriculus. Before entering the proventriculus, food is first stored in the crop. Unlike mammals, birds do not have teeth and cannot chew their food. The physical breakdown of their food mostly happens in an organ called...

To better understand how animals eat their food, it is useful to consider five broad categories: herbivory, carnivory, omnivory, filter-feeding, and scavenging. Herbivorous animals feed primarily on plants or plant products such as fruit, leaves, and nectar.
Food is required by all the organisms. The animal nutrition includes the nutrient requirements, the mode of food intake, and the utilization of food in the body. The intake of food is called ingestion. The ingested food is broken down into simpler substances in the process called digestion.
