Blood Vessels

This overview provides a detailed understanding of blood vessel anatomy and functions. It covers the three main layers of blood vessels: the tunica interna (endothelium), tunica media (smooth muscle), and tunica externa (connective tissue). It distinguishes between arteries, arterioles, capillaries, veins, and venules, emphasizing their roles and differences. The discussion includes the nature of blood flow, the significance of one-way valves, and the differences between oxygenated and deoxygenated blood. This foundational knowledge is crucial for understanding circulatory system health.
