用血管铸型扫描电镜法，观察人腮腺微血管的构筑，从铸型上看，腮腺各小叶的界限分明。小叶的表层为管径粗细一致的毛细血管，它们在腺泡和闰管周围相互吻合成毛细血管网。腺泡和闰管周围毛细血管网起自腺泡微动脉。腺泡微动脉主要起自小叶内动脉，但也可起自小叶间动脉。纹状管周围为毛细血管后微静脉和微静脉用互吻合形成的网状静脉丛。腺泡周围毛细血管通过毛细血管后微静脉注入纹状管周围的微静脉丛，然后注入小叶内静脉。小叶间导管起始部的周围，为一层由毛细血管和毛细血管后微静脉共同形成的微血管网，随着小叶间导管向总导管的延伸，其周围的微血管形成了内、外两层。内层为毛细血管和毛细血管后微静脉共同形成的微血管网，外层为微静脉和微动脉交织而成的血管丛。
Using blood vessel mold scanning electron microscopy to observe the construction of human parotid microvascular, from the mold point of view, parotid lobular boundaries clear. The surface of the leaflet capillary diameter consistent with the thickness of the capillaries, they are in the alveolus and the intercalation of the intercalated capillary network into capillaries. Capillaries around acinar and intercalary vessels originate from the alveolar arterioles. The acinar arterioles originate primarily from the intralobular artery, but can also originate from the interlobular artery. Striped capillary around the micro-venules and micro-venous anastomosis with the formation of reticular venous plexus. The capillaries around the acini are injected into the venules through the capillary venules after they have been injected into the venules around the striated duct. Around the beginning of the interlobular catheter, a layer of capillaries formed by capillaries and post-capillary venules, the capillaries around and around the interlobular ducts extend to the total catheter, forming the inner and outer layers of capillaries around them. The inner layer of capillaries and capillaries after the formation of micro-venous capillary network, the outer layer of micro-venous and arteriolar interwoven vascular plexus.
