Answer:
The digestive system of the human body comprises a group of organs working together to convert food into energy for the body. Anatomically, the digestive system is made up of the gastrointestinal tract, along with accessory organs such as the liver, pancreas and gallbladder. The hollow organs that make up the gastrointestinal tract (GI tract) include the mouth, stomach, oesophagus, small intestine and large intestine that contains the rectum and anus.
Human Digestive System and Nutrition involve the intake of food by an organism and its utilisation for energy. This is a vital process which helps living beings to obtain their energy from various sources. The food which we eat undergoes much processing before the nutrients present in them are utilised to generate energy. This processing is known as digestion. Humans and other animals have specialised organs and systems 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 mono gastric 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 significant role in the digestion process. A combination of nerves, bacteria, hormones, blood and other organs of the digestive system completes the task of digestion.
