Continuous capillary
The diameter of a continuous capillary is about equal to the width of a single red blood cell. Usually only one endothelial cell nucleus is visible in cross section, but sometimes two are visible. The cytoplasm of these cells is greatly attenuated and no fenestrations are present. A capillary has no additional tunics, but a pericyte may lie within the basal lamina of the endothelium. 1000x
