What is the pressure at the venule end of the capillary?

The pressure at the venule end of the capillary is generally around 10 mmHg. This pressure reflects the hydrostatic pressure within the capillaries, which is significantly lower than the arterial side. As blood flows through the capillary network, it encounters resistance, and as a result, the hydrostatic pressure drops, particularly by the time it reaches the venous end. The lower pressure at the venule end is crucial as it facilitates the reabsorption of interstitial fluid and solutes back into the blood, ensuring proper exchange of nutrients and waste products between blood and tissues. This dynamic is essential for maintaining tissue perfusion and fluid balance in the body.
