Cardiovascular System: Blood Vessels and Circulation
Types of Blood Vessels 1.Arteries: Carry blood away from the heart Blood leaving heart starts off in large vessels called arteries Arteries become smaller.
Blood Vessels  Arteries: vessels that carry blood away from heart, surrounded by thick layer of smooth muscle, high levels of BP  Capillaries: microscopic.

Tunica Intima: Loose Connective Tissue decrease friction so blood can flow freely

Tunica Media: Smooth Muscle Constricts and dilates to move the blood

Tunica Externa: Collagen Supports(so it doesn’t collapse) Protects Connects

Arteries Blood flow through the arteries, veins, capillaries https://www.youtube.com/watch?v=VVJJHw_Ocp4
