Organs of the Digestive System

The major organs of the digestive system are:

* Mouth: The mouth is the first part of the digestive system. It is here that food is chewed and mixed with saliva, which helps to break down carbohydrates.

* Esophagus: The esophagus is a muscular tube that connects the mouth to the stomach. It carries food down to the stomach by means of peristalsis, a series of involuntary muscle contractions.

* Stomach: The stomach is a J-shaped organ that secretes gastric juices, which help to break down proteins and fats. The stomach also churns and mixes food, further breaking it down into smaller particles.

* Small intestine: The small intestine is a long, coiled tube that is the primary site of nutrient absorption. The walls of the small intestine are lined with villi, which are tiny, finger-like projections that increase the surface area for absorption. The small intestine also produces enzymes that help to break down carbohydrates, proteins, and fats.

* Large intestine: The large intestine is a shorter, wider tube that is responsible for absorbing water and electrolytes from food. It also stores waste products before they are eliminated from the body.

* Rectum: The rectum is the final portion of the large intestine. It stores waste products until they are eliminated from the body through the anus.

* Anus: The anus is the opening at the end of the digestive system through which waste products are eliminated from the body.

In addition to these major organs, the digestive system also includes several accessory organs, such as the liver, gallbladder, and pancreas. These organs produce and secrete substances that help to break down food and absorb nutrients.
