Fenestrated capillaries

This electron micrograph shows a capillary adjacent to the basal portion of a kidney tubule that is actively involved with water and ion movement between the urine in its lumen and the blood. The fenestrations in the endothelium facilitate this process. The tubule is composed of epithelial cells with numerous basal folds and an unusually thick basal lamina. 40,000x
