The vascular system involves the heart and blood vessels. The blood vessels include arteries, which are tubes that transport blood from your heart to the rest of your body, and veins, which return the blood to your heart. This complex system is involved in many diverse functions, but the most important is transporting vital oxygen and nutrients to your tissues and organs.
ARTERIES are thicker and are prone to developing blockages or dilations.
