Circulatory

• Tunical adventitia: Outer coating
• Tunical media: smooth muscle and elastic tissue middle coating
• Tunica Intima: inner coating of endothelium

• Large veins: Vena Cava
• medium-sized veins: fibular veins
• Small veins: veins in palms of hands
• Venules: slightly larger than capillaries. Untappable
• Capillary: form beds in every tissues in the body; only one blood cell in diameter and very fragile.

• Elastic arteries: largest and thickest: Aorta
• Muscular arteries/distributing: medium sized that go all over the body: brachial
• Small arteries: arteries in fingers and toes
• Aterioles: smallest arteries with three layers,
• Capillary's: very thin, one cell wide

Left ventricle of heart --> Ascending aorta --> aortic arch-->brachiocephalic artery--subclavian artery--axillary artery--brachial artery--radial and ulnar artery-->superficial and deep palmar arches --> digital arteries-->capillaries -->digital veins -->superficial and deep palmer arches veins -->basilic vien or radial and ulnar veins -->brachial veins (if radial or ulnar) OR axillary --> Axillary (if radial or ulnar to start)--subclavian vein-->brachiocephalic vein-->superior vena cava-->right atrium

Heart-->aortic arch--thoracic aorta-->descending aorta-->common iliac artery-->external iliac artery--->femoral artery-->popliteal artery-->tibial arteries-->lateral and medial plantar arteries/dorsalis pedis arteries-->digital arteries-->cappilaries-->digital viens-->dorsal and plantar veins-->fibular and tibial veins, great and small saphenous veins-->popliteal vein --> femoral vein>extrernal iliac vein common iliac vein --inferior vena cava--> heart
