Abstract:
The microvasculature of monkey parotid gland was observed by scanning electron microscope. The capillary networks around the acini were loose and the capillary networks around the ducts were dense and sinusoidal in type. The capillary networks around both the acini and intercalated duct and sinusoidal capillary networks around both the striated duct and intralobular duct were supplied by the blood passing through the acinar or duct arterioles from interlobular and intralobular artery. The capillary networks around the acini showed three draining forms: (1) draining into the vein directly; (2) draining into the capillary network around the striated duct through capillaries; (3) draining into the capillary network around the striated duct through venules. The latter form (venules) is named as "portal system". The capillary networks around the striated duct showed two draining forms: (1) they continued to form the capillary network around the intralobular duct; (2) they converged into venules which accompanied by the intralobular duct. The arterio-venous anastomoses were not observed in the parotid gland. However, arterio-arterial and venovenous anastomoses were found in interlobular region.
