    • The blood vessels in both systems channel the blood from the heart to the tissues and back to the heart
    • Arteries
      → thick-walled structures that carry blood from the heart to the tissues
    • Aorta→ Smaller arteries→ Arterioles
    • Resistance vessels
      → Regulate the volume and pressure in the arterial system and rate of blood flow to the capillaries
    • Capillaries
      → Thin-walled structure that permits rapid and efficient transport of nutrients to the cells and removal of metabolic wastes.
    • Capillaries
      → Site of exchange
      → Changes in size are influenced by contractile changes in the blood vessels.
      → Formed by joined venules (which is formed by joined capillaries)
      → Distend more compared to arteries
      → Has one-way bicuspid valves that prevent blood from seeping backward.
    • SYSTEMATIC CIRCULATION SYSTEM
      → Oxygen to all body cells and carries away wastes
      → Oxygenated blood pumped to all body tissues via aorta
      → Deoxygenated blood returns to heart via venae cavae
    • PULMONARY CIRCULATION
      → Eliminates carbon dioxide via the lungs and oxygenate the blood
      → Oxygenated blood returns to heart via pulmonary veins
    • Arteries - Blood Away from Heart
    • Arteries - higher pressure
    • Arteries - thicker: tunica media thicker than tunica externa
    • Arteries - smaller lumen
    • Arteries - no valves
    • Veins - Blood to Heart
    • Veins - lower pressure
    • Veins - THINNER: Tunica externa thicker than tunica media
    • Veins - larger lumen
    • Veins - One-way bicuspid valves
    • Lymphedema – happens if there is insufficient drainage of lymph fluids
    • Venous obstruction – vein cannot facilitate blood return
    • Raynaud’s disease - white discoloration, arterial insufficiency ( arteries do not deliver enough oxygenated blood)
    • Buerger’s dse. – inflammation of blood vessels and common in male, Compartment Syndrome Scleroderma Arterial occlusion Arteriosclerosis Absent / Diminished
    • Scleroderma
      → Thickening of skin and blood vessels
    • Compartment syndrome
      → a painful build up of pressure around your muscles due to ruptured blood vessel
