1. Review the struc-
ture and function
of the GI tract
2. What role(s) does produces bile
the liver serve?
metabolizes hormones and drugs
synthesizes proteins, glucose and clotting factors
stores vitamins and minerals and converts
them to usable material
changes ammonia to urea
converts fatty acids to ketones.
3. What is the struc- Mucosal layer: Produces mucus that lubricates and protects the inner surface of
ture and function the alimentary canal; Secretes digestive enzymes and substances that break down
of the 4 layers of food; Absorbs the breakdown products of digestion; Maintains a barrier to prevent
the GI wall? the entry of noxious substances and pathogenic organisms.
Submucosal layer: blood vessels, nerves, and structures to secrete digestive en-
zymes.
Muscularis externa: inner layer of circularly arranged smooth muscle cells and an
outer layer of longitudinally arranged smooth muscle layers. These layers help
move the contents through the GI tract.
Serosal layer: which is a serous membrane; outermost layer of organs, called the
visceral peritoneum.
