胞状腺（ほうじょうせん、Alveolar glands）はsaccular glandsとも呼ばれ、管状腺とは対照的に嚢状の分泌部を持つ腺である。胞状腺は通常肥大化したルーメン（内腔）を持ち、肺胞によく似た構造である。 いくつかの情報源は内腔の大きさに基づいて、腺房と胞状腺を明確に区別すると記述されている。[1] A further complication in the case of the alveolar glands may occur in the form of still smaller saccular diverticuli growing out from the main sacculi.
The term "racemose gland"[2] is used to describe a "compound alveolar gland" or "compound acinar gland."[3]
Branched alveolar glands are classified as follows:
| Type | Description | Location | |
|---|---|---|---|
 |
simple branched acinar |
甲状腺 | |
 |
tubuloalveolar or tubulo-alveolar or tubulo-acinar or compound tubulo-acinar or compound tubuloalveolar[4] |
glands that start out as simple branched tubular, and branch further to terminate in alveoli | 唾液腺、[5] 食道、[6] 乳腺 |
