The organs with ducts that lead to the small intestine are the

a. heart and liver

b. gall bladder and pancreas

c. stomach and spleen

d. kidney and large intestine

The right answer is B:

The heart and the spleen do not have ducts that lead to the small intestine, they only have arteries and veins.

Kidneys have ducts but are related to genital organs, and not to the small intestine.

Gallbladder has ducts related to the small intestine to release its bile. The same thing for the pancreas to release its exocrine products like proteases (trypsinogen, chymotrypsinogen, and carboxypeptidase), lipase and amylase.
