The first digestive juices are those produced in saliva that is excreted into the mouth.
When you pop food into your mouth, the saliva glands moisten up the food when you are chewing it to help out the stomach in the digestive process.
The structure in humans that the digestive glands are comparable with crayfish are the glands that are found in the mouth and the stomach. These glands will secrete salivary amylase and HCI respectively to aid digestion in humans.
Yes. They produce acid.
The organs of the digestive system are mouth, esophagus, stomach, small intestine, large intestine and anus. The accessory glands of the digestive system are salivary glands, liver and pancreas.
yes, the small intestine is in the digestive system as the esophagus, mouth, salivary glands, and the stomach.
Salivary glands.
Stomach, esophagus and the endocrine glands.
A cheetah (as with most other carnivores) has an enlarged stomach that represents more than half of its alimentary canal. This is because it is required to eat greater amounts of food compared to other animals.
The stomach is an organ of the digestive system. The digestive system includes other organs such as mouth, salivary glands, oesophagus, intestione, pancreas, liver, etc.
Yes they can be termed as digestive hormones. Salivary glands (saliva, that contains enzymes), glands in stomach (gastrin, promotes gastric juice secretion) and glands in duodenum and intestine (secretin, cholecystokinin (CCK) and gastric inhibitory peptide)
No it shouldn't. The salivary glands and pancreas and liver produce saliva, acid, and bile respectively. The reason you get "heartburn" is because acid from the stomach is being pushed into the esophagus so no, it does not produce digestive enzymes.
Most digestive enzymes are produced in the stomach. You will find that with the complex ducts throughout the human body these enzymes can travel to other areas of the digestive system. These areas include the salivary glands, the stomach, the pancreas, and the intestines.
