Explain about human digestive system
Answers
Answer:
A human digestive system is a group of organs working together in converting food into energy and basic nutrients required for the body. It is made up of the gastrointestinal tract, also called a digestive tract along with liver, pancreas, and gallbladder which constitute the parts of the digestive system. The hollow organs that make up the gastrointestinal tract (GI tract) include the mouth, stomach, esophagus, small intestine, and large intestine that contains rectum and anus.
Human Digestive System and Nutrition involve the intake of food by an organism and its utilization for energy. This is a vital process which helps living beings to obtain their energy from various sources. The food which we eat undergoes a lot of processing before the nutrients present in them are utilized to generate energy. This processing is known as digestion. Humans and other animals have specialized organs and system for this process.
The digestion process involves the alimentary canal along with various accessory organs and organ systems. In humans, the process is quite simple due to our monogastric nature. This means that we have a one-chambered stomach, unlike other animals such as cows, which have four chambers.
Some parts of nervous and circulatory systems also play a major role in the digestion process. A combination of nerves, bacteria, hormones, blood, and organs of the digestive system completes the task of digestion that a person consumes in a day.

The energy required for all the processes and activities that take place in our bodies is derived from the foods we ingest. The digestive system allows us to utilize food from such diverse sources as meat from an animal and the roots of a plant, and utilize them as an energy source. Whether it is the ability to coordinate the chewing of the food without injuring our tongue and lips or the propulsion of the food from the stomach into the duodenum while releasing the appropriate enzymes, our digestive system allows us to manage the process without much thought and often while performing other tasks.What are the 9 parts and and functions of the digestive system
