This lecture covers the principles of capillary filtration and blood flow dynamics. It discusses the factors influencing filtration at the entrance of a peripheral capillary, the balance between filtration and reabsorption, and the effects of changes in arterial pressure on capillary dynamics. The lecture also explores the concept of Reynolds number in blood flow and its implications in stenosis detection. Additionally, it addresses the impact of vascular calcification on blood flow and the relationship between compliance and vascular filling during the cardiac cycle.
