One is the stomach
Gallbladder and pancres
The spleen and the gallbladder are two organs that do not have a digestive system. The spleen is primarily involved in filtering blood and supporting the immune system, while the gallbladder stores and concentrates bile produced by the liver, aiding in fat digestion but not directly involved in the digestive process itself.
1. The Skeletal System 2. The Digestive System
Two or more organs working together are called an organ system.
There are two different organs which are part of the digestive system and which are responsible for breaking down some types of nutrients, these being the stomach and the small intestine. The digestive system also includes other organs but those do not break down nutrients.
At the beginning we have to know that the digestive system consists of two main components :first : the main organs ,which are# the mouth# pharynx# larynx # eosaphogus # stomach # liver # pancrease # small intestine # large intestine # rectum # anal canal + anal sphinctersecond : the accessory organs which includes:# the tongue # slavery glands # appendix
The digestive system in a human is the two ended system that is used to break down and absorb food molecules. It starts at the mouth and ens at the anus. From the mouth is the only part situated in the head and from it extends the Oesophagus, the long tube that carries the food from the neck, through the thorax and into the abdomen. When in the abdomen the oesophagus is attached to the stomach. The whole of the abdomen is filled with organs that are invilved in the diegestive system (exept the kidneys at the back).
Excretion is not part of the digestive system. Excretion takes place in the lungs, kidneys, and the urinary bladder, which expels waste products.
I am tempted towards the stomach and small intestine but in actual fact there is no two more important than any other. All the digestive organs are vital in digestion.
Two organs not part of the digestive system that secrete substances into the stomach and small intestine are the pancreas and the liver. The pancreas produces digestive enzymes and bicarbonate, which are released into the small intestine to aid in digestion. The liver produces bile, which is stored in the gallbladder and released into the small intestine to help emulsify fats.
The skeletal system and the digestive system.
Digestive organs and the system in general can be divided into two parts: the accessory organs and the alimentary canal. The alimentary canal is the GI tract and the accessory organs are things like the teeth, tongue, salivary glands, and gallbladder.
