A microslide contains the preparation of a gland composed of several secretory saccule-shaped parts that open in the common excretory duct. What gland is it?

Answer options

1. Compound unbranched alveolar gland
2. Simple branched tubular gland
3. Simple unbranched alveolar gland
4. Compound branched alveolar gland
5. Simple branched alveolar gland

Explanation

A microslide contains the preparation of a gland composed of several secretory saccule-shaped parts that open in the common excretory duct. What gland is it?Alveolar glands are sac-like (saccule). So "Simple branched tubular gland" is out. There are several secretory parts which mean it's BRANCHED ("Simple unbranched alveolar gland" & "Compound unbranched alveolar gland" is out), but they empty into ONE duct. Compound (means many) won’t empty into one duct. That leaves "Simple branched alveolar gland" is the right answer.
