What is the difference between alimentary canal and accessory digestive organs?

Alimentary Canal

* The alimentary canal is a series of organs that take in, digest, and expel food.

* The alimentary canal begins at the mouth and ends at the anus.

* The mouth is where food is taken in.

* The oral cavity is where food is chewed and mixed with saliva to form a bolus.

* The pharynx is where the bolus is swallowed and begins to travel down the esophagus.

* The esophagus is a muscular tube that connects the pharynx to the stomach.

* The stomach is a muscular organ that secretes gastric juice to break down food into a semi-liquid form called chyme.

* The small intestine is a long, coiled tube where most of the digestion and absorption of nutrients takes place.

* The large intestine is a shorter, wider tube where water and electrolytes are absorbed and waste products are formed into feces.

* The anus is where feces are expelled from the body.

Accessory Digestive Organs

* The accessory digestive organs are organs that help the alimentary canal digest and absorb food.

* The accessory digestive organs include the salivary glands, liver, pancreas, and gallbladder.

* The salivary glands secrete saliva, which helps to break down food in the mouth.

* The liver produces bile, which helps to break down fats in the small intestine.

* The pancreas produces pancreatic juice, which contains enzymes that help to break down proteins, fats, and carbohydrates in the small intestine.

* The gallbladder stores and concentrates bile.
