What is the role of the greenish liquid called bile in the digestive system?
Digestion of proteins
Digestion of fats
Digestion of carbohydrates
Digestion of food
What are the blood vessels inside villus called?

Neurons
Capilliaries
The tongue rolls the food into a shape called the
ball
bolus
holus
bowl
What is the role of saliva in the digestive system? Select the correct answer(s)
To assist in chemical digestion by releasing enzymes to break down starch
To assist in the process of peristalsis
To wet the food making it slippery and slimy and easy to swallow
To assist in the production of gastric juice
Select 3 disorders of the digestive system
Heartburn, hypothyroidism, vomiting
Vomiting, diarrhoea, high blood pressure
Appendicitis, tendonitis, reflux
Appendicitis, vomiting, heartburn
How does the structure of the stomach make it well suited for the job that it does?
The stomach is shaped like a bag and the walls of the stomach do not allow for any contraction or expansion and rely solely on chemical digestion
The stomach is made up of a long thin pipe to carry food from one part of the digestive tract to another
The stomach is shaped like a bag and has the ability to expand to hold food. The muscular walls can relax and contract to further churn the food
Where is gastric juice produced?
Special cells inside the stomach wall
Cells inside the oesophagus
The saliva
Special cells in the small intestine
Gastric juice contains:
Mucus, acetic acid, orange juice
Mucus, hydrochloric acid, digestive juices
Phlegm, hydrochloric acid, digestive juices
Mucus, bile and digestive juices
Identify the part of the digestive system that absorbs most of the nutrients from food
Large Intestine
Stomach
Ileum in the small Intestine
Duodenum in the small intestine
Identify the part of the digestive system that re-absorbs water from the food
Duodenum
Illeum
Appendix
Large Intestine
Identify the part of the digestive system that stops food going down the wrong way
Peristalsis
Epiglottis
Sphincter
Valve
Classifying the following as either mechanical or chemical digestion.
Digestive juice caused a mass of oil to break up into tiny droplets.
Mechanical
Chemical
Classifying the following as either mechanical or chemical digestion.
At the end of an experiment, Amed tested the food for starch and didn't find any but he did find glucose which was not there at the start of the experiment.
Mechanical
Chemical
What would happen to the amount of nutrients being absorbed if the stomach did not have sphincters at its top and bottom
If there were no sphincters the same amount of nutrients would be absorbed as they don't have an active role in the digestive system
If there were no sphincters more nutrients would be absorbed as the contents could move freely through the digestive system and arrive at the small intestine sooner
If there were no sphincters then less nutrients would be absorbed as the contents would not be able to stay in the stomach and when they arrived at the small intestine they would be too big for absorption
What component of gastric juice is responsible for the killing of ingested bacteria
Mucus
Digestive juice
Hydrochloric acid
Bile
