Flashcards in Chapter 14 Anatomy of Cardiovascular System Deck (9):
thicker walls than veins, more pressure, no valves, smaller lumen, and circular shape.
thinner walls than arteries, less pressure, contain valves, larger lumen, and irregular shape.
3 Layers of Cardiac Muscle Tissue
Tunica Media, Tunica Externa, Tunica Intima
CT, outermost layer
smooth muscle and elastic fibers, middle layer
endothelial layer, innermost layer lining the lumen.
more elastic fibers in tunica media
tunica media is reduced/absent, tunica externa is thicker than media.
