Week 13 - Digestive System (Digestive Glands).ppt

digestion

1. The liver is the largest gland structure in the
body. The size and weight is different among
mammals
It is reddish-brown colored in healthy.
Coto
LIVER (HEPAR)

2. The liver has a wide-range of function including ;
Haemopoietic (blood forming) organ of the fetus and relativly larger in fetal period.
PROTEIN SYNTHESIS
It synthesizes the plasma proteins for the body.
STORAGE
It storages the glicogen from the glucose, trigliserides from the fatty acids small
amount of proteins and vitamins.
DETOXIFICATION
It converts the end toxic products of protein break-down as uric acid and urea.
then helps to remove from the kidneys
SECRETION OF BILE
It produces bile from the blood for emulsificatin of lipids. Coto
Functions of The Liver

3. It locates in right hypochondriac region of the
abdominal cavity (epigastrium).
It rests just behindthe diaphragm, and rib cage
It connects with the right kidney, the duodenum
and the stomach from right to left in caudally.

9.  The liver is connected the neigbour structures by peritoneal extension;
 Lig.coronarium
 Lig.triangulare dextrum et sinistrum
 Lig.falciforme hepatis
 Lig.teres hepatis
 Lig.hepatogastricum
 Lig.hepatoduodenale
 Lig.hepatorenale
Coto
Ligaments of the Liver

10.  A storage sac for the bile produced and secreted by
the liver.
 It is located on the visceral surface of the liver.
 Equines and rats has no galbladder.
 Ductus biliferi
 Ductus hepaticus dexter et sinister
 Ductus hepaticus communis
 Ductus cysticus
 Ductus choledochus
Coto
The Gallbladder (Vesica Fella)

11.  Pancreas is a glandular organ for the digestive and
endocrine system.
 Insulin and glucagon are the hormones produced by
pancreas and circulate in the blood
 The digestive enzymes inside the pancreatic juice
empties to the duodenum via pancreatic ducts
Coto
PANCREAS

12.  It is located on the dorsal side of the cranial
abdominal cavity. It has an extensive lobular
structure and fills the space between the liver,
the stomach and the duodenum.

13.  Corpus pancreatis
Incisura pancreatis
