#13

Front (Question)

Name the six digestive processes?

Back (Answer)

• Ingestion • Digestion • Motility • Secretion • Absorption • Elimination • Regulation

#14

Front (Question)

Describe Ingestion?

Back (Answer)

Process of taking food into the mouth, starting its journey through the digestive tract

#15

Front (Question)

Describe Digestion?

Back (Answer)

A group of processes that break complex nutrients into simpler ones, thus facilitating their absorption: mechanical digestion physically breaks large chunks into smaller bits: chemical digestion breaks molecules apart

#16

Front (Question)

Describe Motility?

Back (Answer)

Movement by the muscular components of the digestive, including processes of mechanical digestion: examples include peristalsis and segmentation

#17

Front (Question)

Describe Secretion?

Back (Answer)

Release of digestive juice: some digestive organs also secrete endocrine hormones that regulate digestion or metabolism of nutrients

#18

Front (Question)

What do digestive juices contain?

Back (Answer)

Enzymes, acids, bases, mucus, bile or other products that facilitate digestion

#19

Front (Question)

Describe Absorption?

Back (Answer)

Movement of digested nutrients through GI mucosa and into the internal environment

#20

Front (Question)

Describe Elimination?

Back (Answer)

Excretion of the residues of the digestive process (faeces) from the rectum, through the anus; defaecation

#21

Front (Question)

Describe Regulation?

Back (Answer)

Coordination of digestive activity

#22

Front (Question)

Name the four layers of the digestive tract?

Back (Answer)

• Mucosa, Submucosa, Muscularis, Serosa

#23

Front (Question)

Describe the function of the Mucosa?

Back (Answer)

The innermost layer of the GI wall the layer facing the lumen. Mucosa is made up of three layers an inner mucous epithelium, a layer of loose fibrous connective tissue and a thin layer of smooth muscle.

#24

Front (Question)

Describe the function of the Submucosa layer?

Back (Answer)

The submucosa layer of the digestive tube is composed of connective tissue that is thicker than the mucosal layer. It contains numerous small glands, blood vessels, and parasympathetic nerves that form the submucosal plexus (Meissner plexus).
