WebJul 2, 2024 · Shunt vessels. Shunt vessels are blood vessels that connect blood directly from the arterioles to the venules. This allows for an alternative route for blood flow (i.e. blood bypasses the capillaries). Like arterioles, shunt vessels have walls that can construct & dilate in order to regulate blood flow. Tissue fluid WebThe Shunt equation (also known as the Berggren equation) quantifies the extent to which venous blood bypasses oxygenation in the capillaries of the lung. “Shunt” and “ dead space “ are terms used to describe conditions where either blood flow or ventilation do not interact with each other in the lung, as they should for efficient gas exchange to take place. top knnWebOther articles where shunting is discussed: human respiratory system: Abnormal gas exchange: In shunting, venous blood enters the bloodstream without passing through … top knives operator 7
