Continuous capillary
This electron micrograph shows a portion of the wall of a continuous capillary, demonstrating its thin endothelial lining. Continuous capillaries also show numerous pinocytotic vesicles on both luminal and abluminal surfaces. These vesicles transport materials across the endothelium. Transport is bidirectional, a process called transcytosis. A cell junction is also visible. 40,000x
