GUIDE COMPLETE QUESTIONS AND
SOLUTIONS
●● What is not a function of the digestive system?
Ingestion of nutrients
Absorption of nutrients
Long-term storage of nutrients Movement of nutrients
Breakdown of nutrients
Answer: Long-term storage of nutrients
●● Which membrane is responsible for the covering of organs and
linings of internal body cavities?
Basement membranes
Mucous membranes
Serous membranes
Cutaneous membranes
Synovial membranes
Answer: Serous membranes
,Serous membranes line organs and body cavities that do not open to the
outside environment.
Synovial membranes are only found to line synovial joints. Cutaneous
membranes are body coverings. Mucous membranes are found to line
systems that open to the outside world. Basement membranes are used to
attach epithelial tissues to underlying tissues.
●● Identify whether each of the digestive organs make up the alimentary
canal or whether they are accessory structures.
Alimentary Structures
Accessory Structures
Digestive organ
Stomach
Esophagus
Liver
Pancreas
Rectum
Salivary glands
Answer: Alimentary Structures:
Stomach
Esophagus
,Rectum
Accessory Structures:
Liver
Pancreas
Salivary glands
Alimentary canal structures are those that make up the continuous
pathway for nutrients that begins with the mouth and ends with the
rectum. Of these structures, the esophagus, stomach, and rectum are all
parts of this canal.
Accessory structures are those that aid in digestive processes, but food
never passes through them. Of these structures, the salivary glands, liver,
and pancreas are considered accessory for digestion.
●● Match each digestive process to its correct description.
Introduction of food into the body
Movement of nutrients into the blood stream
Movement of food within the GI tract
Introduction of digestive enzymes into the gastrointestinal (GI) tract
Propulsion
, Absorption
Secretion
Ingestion
Answer: Introduction of food into the body → Ingestion
Movement of nutrients into the bloodstream → Absorption
Movement of food within the GI tract → Propulsion
Introduction of digestive enzymes into the gastrointestinal (GI) tract →
Secretion
●● Based on the description, select the correct layer of the
gastrointestinal (GI) tract from the following: submucosa, mucosa,
muscularis externa, serosa
The layer of the GI tract containing two bands of smooth muscle:
The layer of the GI tract that is composed of blood and lymphatic
vessels, as well as nerves:
The outermost layer of the GI tract:
The epithelial inner lining of the GI tract:
Answer: The layer of the GI tract containing two bands of smooth
muscle: Muscularis externa
