A

Left subphrenic (perisplenic space)

7
Q

Space affected by the disease of the duodenal bulb, lesser curve of stomach, gallbladder and left lobe of liver

A

Left subhepatic space (gastrohepatic space)

8
Q

Most dependent portion of the abdomen in the upright patient

A

Pelvis

9
Q

Consists of two closely applied layers of peritoneum extending from the umbilicus to the diaphragm in a parasagittal plane

A

Falciform ligament

10
Q

Caudal free end of falciform ligament contains the

A

Iigamentum teres

11
Q

Reflections of the falciform ligament separate over the posterior dome of the liver forming the _____ which define the bare area of the liver not covered by peritoneum

A

Coronary ligaments

12
Q

Prevents access of ascites and other intraperitoneal processes from covering the bare area of the liver

A

Coronary ligaments

13
Q

Lesser omentum is composed of

A

Gastrohepatic and hepatoduodenal ligaments

14
Q

Separates the gastrohepatic recess of the left subphrenic space from the lesser sac

A

Lesser omentum

15
Q

Lesser omebtum transmits

A

17
Q

Isolated peritoneal compartment between stomach and pancreas

A

Lesser sac

18
Q

Lesser sac communicates with the peritoneal compartment thru what small foramen

A

Foramen of winslow

19
Q

Pathologic processes in the lesser sac usually occur because of disease in the

A

Pancreas and stomach

20
Q

Double layer of peritoneum that hangs from the greater curvature of stomach and descends infront of the abdominal viscera, separating bowel from the anterior abdominal wall

A

Greater omentum

21
Q

Serves as a fertile ground for implantation of peritoneal metastases and assists in loculation of inflammatory processes of the peritoneal cavity such as abscess and tuberculosis

A

Greater omentum

22
Q

Retroperitoneal space is divided into
