Question

what is the function of each of the digeztive system, including the accessory organs?

Answer 1

digestive system of the body helps to digest the complex food by breaking down it into simpler molecules to absorb easily for energy production.

digestive system of the body includes various organs having particular functions. each one of the organs is discussed below.

mouth - food begins its journey from the oral cavity and it has various accessory organs - salivary glands, teeth, and tongue.

teeth masticates the food, tongue mixes the food with the salivary enzymes and salivary glands secrete digestive enzymes to breakdown the food and lubricate it for an easy passage.

pharynx - it is responsible for passing the masticated food to the esophagus (food pipe).

esophagus - it is a long tube and also known as the food pipe. it connects pharynx to the stomach.

stomach - it is a muscular sac in which food comes and various digestive enzymes act upon it. it is the major organ where food is stored for some time and hydrochloric acid and pepsin acts on it.

small intestine - it is a long thin coiled tube in the lower gastrointestinal tract. the folds of the small intestine increase the digestive area for maximum absorption of the food. it is the place where major digestion takes place with the secretion of digestive juice and enzymes.

liver and gall bladder - main function of liver is to secrete bile juices for the digestion of lipids. gall bladder stores excess bile juice and recycles excess bile for reuse.

pancreas - it secretes digestive enzymes into the small intestine to complete the digestion process.

large intestine - its main function is to absorb water and minerals.
