Which capillary would be least likely to allow substances to enter or exit the blood due to tight junctions that join the endothelial cells?

Question

Quizplus · Accepted Answer

Continuous capillaries have tight junctions that join the endothelial cells, making it difficult for substances to enter or exit the blood. Closed capillaries do not exist, and sinusoidal capillaries and fenestrated capillaries have bigger gaps between the endothelial cells that allow substances to easily enter or exit the blood.
