Capillary Bulk Exchange Filtration & Reabsorption

The video tutorial explains capillary exchange, focusing on nutrient and waste movement between blood and tissues. It covers mechanisms like simple diffusion and vesicular transport, and delves into bulk exchange driven by pressure differences between arterial and venous ends of capillaries. The tutorial details forces acting on capillary walls, such as blood hydrostatic and colloid osmotic pressures, and explains filtration and reabsorption processes. It concludes with a summary of key points, emphasizing the role of pressure differences in fluid dynamics and the importance of the lymphatic system in returning excess fluid to the blood.
