Write the functions of the following organs of our digestive system
1. Salivary glands 2. esophagus 3. Stomach
Answers
Answer:
Salivary gland. The salivary glands produce saliva, which keeps the mouth and other parts of the digestive system moist. It also helps break down carbohydrates (with salivary amylase, formerly known as ptyalin) and lubricates the passage of food down from the oro-pharynx to the esophagus to the stomach.
2.The esophagus is a tube that connects the throat and the stomach. If the mouth is the gateway to the body, then the esophagus is a highway for food and drink to travel along to make it to the stomach. This body part has a very simple function, but can have many disorders.
3.The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
