Question

Describe the function of each organ through which food passes as it moves through the digestive tract.

Answer 1

The digestive system consists of several organs through which food passes: mouth, pharynx, esophagus, stomach, small intestine, and large intestine.

Step-by-step explanation:

The digestive system consists of several organs through which food passes as it moves through the digestive tract:

1)Mouth: Ingestion of food occurs in the mouth. Chewing breaks down the food into smaller pieces.

2)Pharynx: The pharynx is a passage that leads from the mouth to the esophagus.

3)Esophagus: The esophagus connects the pharynx to the stomach and uses peristalsis to push food down into the stomach.

4)Stomach: The stomach is a muscular organ that mixes food with digestive juices and continues the breakdown process.

5)Small Intestine: The small intestine is where most of the absorption of nutrients from food takes place. It is lined with villi, which increase its surface area for better absorption.

6)Large Intestine: The large intestine absorbs water from the remaining food waste and forms it into feces, which will be eliminated through the anus.

Answer 2

The digestive system is made up hollow organs that consists of the mouth, esophagus, stomach, small intestine, large intestine and anus, sequentially. The supplementary organs are the liver, pancreas and the gall bladder.

The food enters first through the (1) MOUTH where mastication or the mechanical breakdown of food particles takes place. After the food is being swallowed it passes through the (2) ESOPHAGUS which is the conduit between the pharynx and (3) STOMACH which secretes acid and enzymes that chemically breaks down food that is termed as chyme. It comprises 10% of the digestion and absorption. The chyme or partially digested food goes to the (4) SMALL INTESTINE where 90% of the digestion and absorption takes place. Its main functions is to absorb the nutrients and minerals from the chyme. (5) The LARGE INTESTINE is where the water from the remaining indigestible food matter is being absorbed. It also transmits the useless waste material from the body where it is excreted through the (6) ANUS
