Answer:
The answer is 1) Pylorus, 2) Mesentery
Step-by-step explanation:
The small intestine extends from the stomach at the level of the pylorus, to the large intestine. It is suspended in the abdomen by the mesentery that fixes it to the posterior abdominal wall.
The mesentery is a thin sheet of tissue, continuation of the peritoneum that is made up of two portions, one internal or visceral and the other external or parietal.
