Arteries and veins are joined by a network of capillaries.

Notably, the excessive nerve fibers were concentrated around tiny muscular valves, called arteriole-venule (AV) shunts.

Outcome Measures: Average number and area of microvascular leaks to fluorescent albumin per unit length of venule.

Arterial venule shunts control whether your blood stays in the larger vessels or flows into smaller ones called capillaries.

venule - Veins and venules of the pulmonary circuit transport oxygen-rich blood from the the alveoles to the heart.

Notably, the excessive nerve fibers were concentrated around tiny muscular valves, called arteriole-venule (AV) shunts.

Average number and area of microvascular leaks to fluorescent albumin per unit length of venule.

Fibrovein containing sodium tetradecyl sulfate is administered directly into the lumen of the isolated segment of vein/venule.

These critical sites are tiny muscular valves, called arteriole-venule (AV) shunts, which form a direct connection between arterioles and venules (see diagram)

A capillary is a small blood vessel, located between an arteriole and venule, whose thin wall permits the diffusion of gases, nutrients, and wastes.
