the role of the liver is to produce bile, metabolize hormones and drugs ,
synthesizes proteins, glucose and clotting factors ,stores vitamins, and
minerals, converts them to be useable by the body. also to change
ammonia to urea, and converts fatty acids to ketones. the liver can
store large amounts of glucose as glycogen, synthesize glucose from
amino acids , glycerol and lactic during times of fasting or increased
demand convert excess carbohydrates to triglycerides for storage in
adipose tissue, major site for protein synthesis and degradation.

1- mucosal layer
it is made up of epithelium an an underlying connective tissue called the
liminal proprietor and smooth muscle cells that can contract and change
the shape and the surface area of the mucosal layer. this layer has
many functions.
it produce mucus that lubricate and protects the inner surface of the
alimentary canal.
it secretes digestive enzymes and substances that break down food.
it absorbs the breakdown products of digestion
it maintains a barrier to prevent the entry of noxious substances and
pathogenic organisms
2- submucosal layer
contains dense connective tissue and some adipose tissue. this layer
has blood vessels, nerve, structures that secret digestive enzymes.
3- muscular externa
consist of an inner layer of circularly arrange smooth muscle cells and
an outer layer longitudinally contract to help move the contents through
the GI tract peristalsis
4- septal layer
this is the outer layer of the organ and it is also called the visceral
peritoneum . the peritoneum is the the largest serous membrane in the
body. it is comprised of two continuous layers the visceral and parietal
peritoneum . the parietal peritoneal cavity, a potential space containing
fluid secreted by the Seoul membranes. this serous fluid keeps a moist
surface to prevent friction between the moving abdominal organs.
