Continuous capillary, illustration 插畫檔

Illustration showing a three-dimensional structural model of a continuous capillary. Closely packed endothelial cells line the vascular lumen and establish a continuous barrier through tight junctions to regulate substance exchange. A continuous basement membrane envelops the abluminal surface of the endothelial cells, providing structural support. Pericytes are situated peripherally, with their cytoplasmic processes encircling the capillary wall to modulate capillary blood flow and vascular permeability
