*Bile is needed to break down fat.

        The Liver produces and secretes bile.  The Gallbladder stores and concentrates bile. The Pancreas produces and secretes its enzymes.

The bile passes through the cystic duct which joins in common hepatic ducts to form a common bile duct. The common bile duct joins the pancreatic duct to form hepatopancreatic duct which enters the duodenum (first part of the small intestine).

Right and Left Hepatic Ducts carrying bile from the liver join to form the Common Hepatic Duct. The Common Hepatic Ducts joins with the Cystic Duct carries bile from Gallbladder to form the Common Bile Duct. The Common Bile Duct joins the Pancreatic Duct from the Pancreas to form the Hepatopancreatic Duct which enters the Duodenum.

The peritoneum is the serous membrane that lines the abdominal cavity (National Institutes of Health).
Greater Omentum is a part of the Peritoneum (equal to the pleural membrane in the lungs or the pericardial membrane). It resembles “cheesecloth” and covers the organs and protects them. It infiltrates Adipose Tissue.

Mesentry is part of the Peritoneum that encases and holds the jejunum and ileum to the posterior wall of the abdomen.

83
Q

Know where the pancreas is and its differents parts, and what is holding it in place

A

Vestibule is the space between the teeth and the lips.

85
Q

Know the large intestine with respect to the bulges, where the appendix is in relationship to the large intestines

A

The bulges are the saccule or haustra formed because the taenea coli is too short.

        Vermiform Appendix (8 cm) can vary in its length and can vary in which direction it is pointing.
86
Q

Know where the teniae coli is specifically.

A

Running from the external surface of the caecum to the sigmoid colon is a longitudinal muscular band called Teniae Coli is shorter than the length of the colon so it forms a series of sacculations called haustra. Hanging off the teniae coli are globules of fat called epiploic appendages.

87
Q

Know what makes up the anal canal

A

The anal canal is at the distal end of the rectum. It extends 4 cm below the pelvic diaphragm and deviates posteriorly at right angles from the rectum. It has smooth (internal sphincter) and skeletal (external sphincter) muscles.
