Incorrect. The bulk of the small intestine is located inferior to the stomach and not posterior to it (technically the 1st part of the duodenum is adjacent to the lesser sac as the hepatoduodenal ligament forming the epiploic foramen connects to the 2nd part of the duodenum).

Correct!  The pancreas is posterior to the stomach and serves as the inferior aspect of the lesser sac.    

Correct! The left kidney is partially posterior to the stomach and adjacent to the posterior side of the lesser sac. 

Incorrect. The lesser sac is on the left side, posterior to the stomach, which does not extend to the right side of the body.

Correct! The lesser sac is posterior to the stomach so by definition the stomach is adjacent to the lesser sac.

Correct. The superior part of the lesser sac is close to the caudate and left lobes of the liver. The hepatoduodenal ligament forms the epiploic foramen connects to the point between the left and right lobes of the liver, thus left and posterior parts of the liver are adjacent to the epiploic foramen).

Correct!  The spleen is located left and posterior to the stomach with the gastrosplenic ligament connecting it to the stomach. The posterior parts of the spleen are adjacent to the lesser sac.

Incorrect. The gallbladder is superior and right of the hepatoduodenal ligament. Thus the gallbladder is in contact with the greater, not the lesser, sac.
