Lecture
This lecture covers the structure and function of elastic arteries, which are large vessels that transport blood from the heart to different circulations. The elastic tissue in the arterial wall allows these arteries to expand and contract during the cardiac cycle, aiding in blood flow. The three layers of elastic arteries - Tunica Intima, Tunica Media, and Tunica Adventitia - are discussed in detail, highlighting the composition and role of each layer. The importance of smooth muscle cells in maintaining collagen and elastic fibers is also explained.
