The digestive system, anatomy, physiology and pathology

Published on 22nd May 2017

Facts to help you revise the anatomy and physiology of the digestive system

The digestive system is one of the 12 systems in the body taught in our anatomy, physiology and pathology course.

It is important for all therapists to understand, not just nutritionists as the digestive system can be affected by many therapies including massage (which can relieve constipation for example) and reflexology.

Here is a quick quiz on the anatomy, physiology and pathology of the digestive system;

Digestive System- Match the term with the description

Absorption,   Gastrin,   Secretion,  Intrinsic Factor,  Ingestion,  Hydrochloric acid,   Pepsinogen,   Motility,   Mucous.

1 Protects stomach lining

2 Transport of water, ions and nutrients from the lumen, across the epithelium and into the blood.

3 Changes into pepsin in stomach acid –the enzyme that breaks down protein

4 Delivery of water, enzymes, mucous, ions, etc. into the lumen; delivery of hormones into blood

5 Important for absorption of vitamin B12

6 Increases secretion of gastric juices; increases motility of tract; relaxes pyloric sphincter

7 Generates acid environment; kills bacteria

8 Contractions of smooth muscle in the wall of the tube that crush, mix and propel its contents

9 Eating

Read the statements and then decide whether it is true or false

1. The job of the digestive system is to break down food so that our bodies can use it as fuel or energy.

4. The oesophagus is a muscular tube that carries food from our mouth to our stomach

Testimonials

"The anatomy and physiology courses are very easy to use, you don't have to be a computer wiz. The tutor giving the lectures is very good and it feels as if your are sitting in the classroom with her. I like the fact that you are able to pause the films to complete worksheets and that you can go back and watch the films over again. Overall, it's a very good course and well worth the money."
