Vedclass · Answer

(B) The numbered structures are: $1$ (stomach), $2$ (pancreas), $3$ (small intestine), $4$ (appendix), $5$ (gallbladder), and $6$ (salivary glands).Digestive enzymes are secreted by:- Salivary glands $(6)$: secrete salivary amylase.- Stomach $(1)$: secretes pepsin.- Pancreas $(2)$: secretes pancreatic amylase, lipase, and trypsinogen.- Small intestine $(3)$: secretes intestinal enzymes (e.g., maltase, lactase).Gallbladder $(5)$ stores bile produced by the liver, which emulsifies fats but does not contain digestive enzymes. The appendix $(4)$ does not secrete digestive enzymes.Therefore, the structures that secrete digestive enzymes are $1, 2, 3,$ and $6$.
