Digestive organs

Digestive organs（It does, the ょ う scratching)

The multicellular organisms, especially animal,FoodIntake, digestion, from the food which was digested nutrient,ExcretionAnd, conveyance in order to do those, with the function which was said is borne organ group. In addition, those organ,Digestive organs system(It does and it handles the ょ う to be can be effective) with as the organ system which is said.

Function

Digestive organs system is divided into two broadly.

• Alimentary canal - While digesting the food, the tube which it conveys
• Digestion gland - It synthesizes and the gland which secretes the various secretes which help digestion

The alimentary canal exists to internal of the animal, but usually there, the entrance of the food () with the exit such as mouth (AnusAnd so on) it is. It takes in the food from the entrance and (intake), while passing by inside the tube, it is digested, the necessary nutrient after being absorbed through the wall of the tube, those which remain it is excreted from the exit flight, as droppings and the like. The inside of this tube is connected outside the body (the outside world) with. It can do from this, the inside of the alimentary canal not to be internal, to be outside the body. Therefore, as for wall of alimentary canal, skin and the like, also function of the boundary which divides inside and outside the body is held. In addition, the secreting fluid is secreted from the digestion gland which discharges the secreting fluid which includes the digestion enzyme and the like mainly to the digestion inside of pipe through the tube which flows into inside the alimentary canal, but because you think this, that those are discharged to outside the body, it is classified as the exocrine gland.
