Explain briefly the digestive system of human beings.
Answers
Answer:
The human digestive system is a series of organs that converts food into essential nutrients that are absorbed into the body. The digestive organs also move waste material out of the body. The enzymes in saliva help break down foods, and the lubrication function of saliva makes it easier for food to be swallowed
Answer:
The largest parts of the digestive system include:
Esophagus: A hollow tubular organ in the neck and chest area that connects the mouth to the stomach. Muscles here propel food to the stomach.
Stomach: A large organ that holds and digests food through a cocktail of enzymes and acids. Food remains here for two to eight hours.
Liver: This organ helps filter toxins from the blood and produces bile, which helps break down proteins, carbohydrates, and fats.
Gallbladder: This sac-like organ stores bile produced by the liver and then releases it as necessary.
Pancreas: This organ produces insulin, which aids in the metabolism of sugars.
Small intestine: The small intestine receives food from the stomach and begins to break down the food while absorbing the majority of its nutrients.
Large intestine: This organ is filled with billions of harmless bacteria that turn food into feces while removing water and electrolytes for the body’s use.
Rectum: At the end of the large intestine, this small space is a temporary storage area for feces.
Anus: This is the external opening of the rectum, through which feces are expelled.
