noun
acinus
Anatomical term for a small sac-like structure in a gland, such as in the pancreas or salivary glands. Used in medical and biological contexts.
膵臓の腺房細胞は消化酵素を分泌する。
The acinar cells of the pancreas secrete digestive enzymes.
唾液腺の腺房が炎症を起こしている。
The acini of the salivary glands are inflamed.
腺 means 'gland' in general, while 腺房 specifically refers to the acinus, the functional unit of certain glands.
腺胞 is a near-synonym also meaning 'acinus' or 'glandular follicle', but 腺房 is more common in modern anatomical terminology.
Compound of 腺 (sen, 'gland') and 房 (bō, 'chamber' or 'sac'), literally 'gland chamber'. The term is a modern anatomical coinage based on the structure of exocrine glands.
