Question

the ________ of the small intestine receives food from the stomach.
a cecum
b jejunum
c ileum
d duodenum

Explanation:

The small intestine has three parts: duodenum, jejunum, and ileum. The duodenum is the first part that directly receives food (chyme) from the stomach via the pyloric sphincter. The cecum is part of the large intestine, not the small intestine. The jejunum is the second part of the small intestine (after the duodenum), and the ileum is the third part. So the correct part that receives food from the stomach is the duodenum.

Answer:

D. duodenum
