Histology of Liver and Pancreas

Histology of Liver and Pancreas

.

Liver Histology :

The liver is the largest internal organ of the human body, weighing approximately 1.5 kg. Embryologically it develops from the foregut and it spans the upper right and part of left abdominal quadrants. Anatomically the liver consists of four lobes: two larger ones (right and left) and two smaller ones (quadrate and caudate).

Pancrea Histology :

The pancreas is both an exocrine accessory digestive organ and a hormone secreting endocrine gland. The bulk of the pancreatic tissue is formed by the exocrine component, which consists of many serous pancreatic acini cells. These acini synthesize and secrete a variety of enzymes essential to successfully “rest and digest”. But don’t let the nirvana after a great meal fool you. While “resting” sounds really nice, the “digesting” part involves some heavy machinery. This is where the pancreas comes at play. Every day, this organ is maneuvering dangerous digestive enzymes, and one little slip up could cause its own self destruction. Talk about occupational hazard!
