Ten cates 8th edition大概寫這樣
Striated Ducts p. 268
...The overall diameter of the duct is greater than that of the secretory end pieces, and the lumen is larger than those of the secretory end pieces and intercalated ducts. A basal lamina encloses the striated duct, and a capillary plexus is present in the surrounding connective tissue.

Connective Tissue p.271
The connective tissue of the salivary glands includes a surrounding capsule, variably developed, that demarcates the gland from adjacent structures. Septa that extend inward from the capsule divide the gland into lobes and lobules and carry the blood vessels and nerves that supple the parenchymal components of the excretory ducts that convey saliva to the oral savity.
Blood Supply p.273
One or more arteries enter the gland and give rise to smaller arteries and arterioles that tend to follow the path of the excretory ducts. The arterioles break up into capillaries that are distributed around the secretory end pieces and striated ducts.
