Answer 2

Answer:

1. Function of salivary gland :

Saliva is important to lubricate your mouth, help with swallowing, protect your teeth against bacteria, and aid in the digestion of food. The three major pairs of salivary glands are: parotid glands on the insides of the cheeks.

2. Function of stomach :

The stomach has 3 main functions: temporary storage for food, which passes from the esophagus to the stomach where it is held for 2 hours or longer. mixing and breakdown of food by contraction and relaxation of the muscle layers in the stomach. digestion of food

3. Function of liver :

The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver.

4. Function of Rectum :

The rectum's job is to receive stool from the colon, let you know that there is stool to be evacuated (pooped out) and to hold the stool until evacuation happens.

5. Function of small intestine :

The small intestine carries out most of the digestive process, absorbing almost all of the nutrients you get from foods into your bloodstream. The walls of the small intestine make digestive juices, or enzymes, that work together with enzymes from the liver and pancreas to do this.

6. Function of large intestine :

The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place.
