Kapillärhydrostatiska

Kapillärhydrostatiska refers to the hydrostatic pressure within capillaries. This pressure is a crucial component in the movement of fluid across the capillary walls, a process known as filtration and reabsorption. It is primarily generated by the pumping action of the heart, which drives blood through the circulatory system. The hydrostatic pressure within the capillaries is typically higher at the arterial end and lower at the venous end due to resistance encountered along the capillary bed. This pressure gradient facilitates the movement of fluid and small solutes from the blood into the interstitial space, a process essential for nutrient and oxygen delivery to tissues. Conversely, at the venous end, a lower hydrostatic pressure, combined with osmotic forces, helps to draw fluid back into the capillaries, maintaining fluid balance within the body. Changes in capillary hydrostatic pressure can significantly impact tissue hydration and overall circulatory function.
