1/3

• Salivary glands

• Small intestine

• Stomach

• Tongue

• Rectum

Word bank:

• Alimentary canal

• Anal canal

• Epiglottis

• Esophagus

• Large intestine

• Oral cavity

The ______________________________ is a single, continuous tube that includes the oral cavity,

esophagus, stomach, and intestines.

The ______________________________ contains the teeth, tongue, and hard and soft palates. Food,

also known as the bolus, passing through here is chewed by the teeth and partially digested by

saliva.

The ______________________________ secrete saliva to aid in chewing and swallowing of the bolus,

beginning chemical digestion.

The ______________________________ works with the teeth to break down food into small masses that

can be swallowed.

The ______________________________ prevents choking by folding down to close off the larynx and

trachea, directing the bolus into the esophagus.

The ______________________________ is a long, hollow, muscular tube that extends from the pharynx

to the stomach. It’s the pathway for the bolus to enter the stomach.

The ______________________________ has four regions and three layers, provides food storage, and

breaks down ingested food into chyme.

The ______________________________ has three regions, the duodenum, jejunum, and ileum.

Name: __________________________________________________________ Date: ______________________________

2/3

The ______________________________ is composed of the colon, cecum, appendix, rectum, and anal

canal. The final phases of digestion, absorption, and elimination occur here.

The ______________________________ is the final segment of the large intestine and serves primarily

to store and expel solid waste. It’s a tube that’s approximately 12 cm long.

The ______________________________ is located at the inferior end of the rectum and extends to the

anus. It’s the termination point or end of the alimentary canal. It temporarily stores solid waste

that’s ready to be eliminated from the body.

Activity 2: Digestive Lab

Structure list:

1. Common bile duct

2. Common hepatic duct

3. Cystic duct

4. Gall bladder

5. Liver, left lobe

6. Liver, right lobe

7. Pancreas

1/1

Gastric juices, produced in the gastric gland and containing hydrochloric acid and

enzymes, digest food into chyme.

Solid waste is temporarily stored in the rectum before it is passed through the anal canal.

The tongue rises to the roof of the mouth, directing the bolus out of the oral cavity.

Food is consumed and taken into the oral cavity.

Pancreatic juice enters the duodenum through the pancreatic ducts to aid digestion in the

small intestine.

The bolus passes from the oral cavity to the pharynx and into the esophagus.

Chyme travels through the small intestine, where nutrients are absorbed into the

bloodstream.

Food is broken down into a small mass called the bolus by being chewed and mixed with

saliva that is secreted by the salivary glands.

Chyme travels through the large intestine, where water and specific vitamins are absorbed

and the remaining waste materials pass to the rectum.

Peristaltic waves move the bolus down the esophagus into the stomach.

1. Review how food travels through the digestive system.

• Read the articles here: https://www.visiblebody.com/learn/digestive.

• Number the following statements, from 1 to 10, to accurately show the path food takes through

the digestive system.

Activity 3: Digestive Lab

1/1

Find the following structures of the tongue.

Papillae are elevations on the tongue, some of which contain taste buds. In the 3D model, find

the vallate papillae: Each contains 100-300 taste buds. Fungiform papillae are shaped like

mushrooms: Each contains about 5 taste buds.
