猴下颌下腺有两种管径和构筑形式明显不同的毛细血管网,即腺泡周围毛细血管网和纹管周围毛细血管网。两种血管网分别由来自小叶内微动脉的毛细血管前微动脉供血。在两种毛细血管网之间藉,毛细血管和毛细血管后微静脉两种形式相连,后者又称为门脉血管。纹管周围毛细血管的回流血管形式为:1.先汇集成毛细血管后微静脉,再注入小叶内静脉;2.直接延续为小叶内导管周围毛细血管网。导管周围毛细血管网除借助毛细血管分别与腺泡及纹管周围毛细血管网相连外,还直接有导管周围毛细血管前微动脉供血。小叶内微动脉的管壁可见有环形缩窄。
The monkey submandibular gland has two distinctly different capillary networks with different diameters and structures, namely the capillary network around the acinar and the capillary network around the canal. The two vascular networks were each supplied with pre-capillary capillary arterioles from the arterioles of the leaflets. Bordered between the two capillaries, capillaries and capillaries after the two forms of micro-venous connection, which is also known as portal vein. Capillary vascular reflux around the vascular form as: 1. First converged into capillary venules, and then injected into the leaflet vein; 2. Direct continuation of the capillary network around the lobular catheter. Capillary network around the catheter in addition to the capillaries with capillaries and acinar capillaries are connected around the network, but also directly around the catheter capillaries before the arterial blood supply. Hypothalamic arteriole wall shows a narrow ring.
