Definitions:

Fenestrated Capillaries

These are specialized capillaries with pores in their endothelial lining, allowing for the efficient exchange of larger molecules like proteins.

Endothelial Cells

Cells that constitute the lining of the inner surfaces of lymphatic and blood vessels, creating a barrier between the blood or lymph flowing within the lumen and the exterior of the vessel wall.

Capillary

The smallest blood vessels in the body's circulatory system, connecting arterioles to venules and facilitating the exchange of water, oxygen, carbon dioxide, and many other nutrients and waste substances between blood and tissues.

Arteriole

Minute artery with all three tunics that transports blood to a capillary.
