Gallbladder...
Gallbladder (Lat. vesica fellea) (also called bladder bag incorrectly) -
pear-shaped organ used for storage and concentration of bile until it
is needed to digest food.
Gallbladder has a length of 10 inches and looks darker than the liver
because of its high content of bile. It is connected with the liver and
the duodenum through the bile ducts. Anatomically, the follicle is
divided into three parts:
bottom (from the Latin fundus)
core (Latin corpus)
neck (Latin collum), passing in the cystic duct.
Some species of mammals (eg, horse, deer and rat) did not have a
gallbladder and duodenal bile flows into the hepatic duct.
Vascularization and lymph drainage
Gall bladder is vascularized alveolar artery (a. cystica) extending from
the right branch of proper hepatic. The outflow of blood takes place
through vesicular vein (v. cystica), which flows into desired portal
(10%) or it is heading directly to the liver for hepatic recess ending
on the network pilonidal liver tumors.
Lymph flows toward the cystic lymph node (nodus lymphaticus cysticus),
lying at the junction of the cystic duct with the hepatic duct, from
flowing into the nodes at the hepatic artery. Lymph from the part
adjacent to the liver gets into the lymphatic vessels of liver
parenchyma.
