#1: List 3 hormones that are involved in the digestive system
and give their site of origin, what they do and what are their
targets.
#2: The kidney regulates blood pressure. List 3 hormones that
are involved in regulating one’s blood pressure. Give their site of

It is known that glucose entering the blood from the digestive
tract causes a more significant increase in the insulin content in
the blood compared to the same amount of glucose, but administered
intravenously. Explain this phenomenon, taking into account the
results of the synthesis and secretion of insulin by beta-cells of
the pancreatic islets of Langerhans.
For the answer:
1. Write the name of the molecules involved in regulating the
secretion of insulin betta by the cells of the...
Q2. Describe the basic four layers of the wall of the
digestive tract. Be sure to include tissue types found there and
the function of the layer.
Mucosa – Absorption and secretion
Epithelium
Lamina Propria
Muscularis mucosae
Submucosa – Supports mucosa
Muscularis Externa – Motility that propels food and residual
through the digestive tract
Inner circular layer
Outer longitudinal layer
Serosa – Secretion of fluid that reduces the friction from the
muscle movement
Areolar tissue
Mesothelium
Q3. Though that basic...
Explain the general functions of the digestive

Describe the flow of foodstuff through the digestive tract
starting with ingestion at the buccal cavity and end with
defecation at anus. For each region state (1) which enzymes are
secreted if any, (2) what the substrates of that enzyme would be in
