Q

What are the parts of the gallbladder?

A

Fundus
Body
Neck, ends in the cystic duct

17
Q

What is the function of the gallbladder?

A

Stores and concentrates bile
When the food passes to the small intestine from the stomach, the gallbladder ejects bile into the duodenum

18
Q

What is the blood supply of gallbladder?

A

Cystic artery, a branch hepatic artery

19
Q

What is the bile pathway?

A

Produced by liver
It travels down the right and left hepatic ducts
They join together forming the common hepatic duct
This duct is joined by the cystic duct of the gallbladder
Their union forms the common bile duct
This duct is joined by the pancreatic duct at the head of pancreas and they open in the duodenum

20
Q

What is pancreas?

A

Its a mixed exocrine and endocrine gland

21
Q

What is the exocrine pancreas?

A

Secrets the pancreatic juice that aids in digestion process.
It reaches the duodenum by the pancreatic duct

22
Q

What is the endocrine pancreas?

A

Secrets hormones, primarily insulin and glucagon, directly into the blood stream

23
Q

What is the relation of the pancreas?

A

Lies posterior and inferior to the stomach

24
Q

What are the parts of the pancreas?

A

Head → lying in the concavity of the duodenum
Body → passing transversely to the left
Tail → being in touch with the hilum of the spleen

25
Q

What is the blood supply of the pancreas?

A

Splenic artery

26
Q

What is spleen?

A

Lymphoid organ ( concerned with body immunity)
Has impressions on its surface, indicating the organs it’s in contact with
Lies below the diaphragm, posterior and lateral to the stomach

27
Q

What are the relations of the spleen?

A

Anteriorly → stomach (gastric impression)
Inferiorly → left colic flexure (colic impression)
Medially → left kidney (renal impression)
Tail of the pancreas in the Hilum of the spleen
