Exocrine glands classified as compound tubular have what kind of ducts?

Answer 1

Branched.

Compound tubular glands are glands that have branched ducts. So the duct of a compound gland branches repeatedly. This in contrast to simple glands that consist of a single secretory passage / an unbranched common duct.

Depending on the shape of the secretory portions they can be further divided into:

Compound tubular glands e.g. in testis and kidney
Compound alveolar glands e.g. in pancreas
Compound tubulo-alveolar glands e.g. salivary gland (see image), mammary gland

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
