The human digestive system labelling quiz
Food is used by the body to grow, function properly, and fix itself; as we eat, our digestive system breaks down and reassembles food into nutrients, such as carbohydrates, fats, proteins, vitamins and minerals, which are used for fuel, building muscle, and many other needs.
In this human digestive system labelling quiz, you can learn to better differentiate the various parts and organs of the digestive system.
As one of the longest organ systems in the body, the digestive system involves multiple parts – from the mouth all the way to the anus. These parts have multiple roles. Some parts assist in breaking food down mechanically or chemically, some absorb water and nutrients, and some move the digested material further down the system through peristalsis.
We can divide the digestive system into two components. The first is a long tube called the gastro-intestinal tract, which is comprised of the mouth, esophagus, stomach, small and large intestines, rectum and anus.
The second is made of different accessory organs, like the liver, pancreas and gallbladder. These organs provide useful substances that aid in food digestion. Examples of the substances are digestive enzymes from the pancreas and bile from the gallbladder.
While studying the parts of this system can be hard to digest, this human digestive system labelling quiz will serve as a useful study aid.
