The video tutorial explains the three main groups of blood vessels: arteries, veins, and capillaries, focusing on their histological structure. It highlights the functions and structure of arteries, including their role in transporting blood under high pressure. The tutorial also covers the transition from arteries to arterioles and capillaries, where gas exchange and nutrient supply occur. Finally, it describes how venules collect blood from capillaries and return it to the heart.
