Arteries
Thick Walls
Carry and move blood AWAY from heart
Carry oxygenated blood
What specific arteries carry deoxygenated blood?
Pulmonary Arteries
Capillaries
Smallest blood vessels
Materials can leave blood and enter surrounding tissue
Veins
Thin Walls
Carry and move blood INTO heart
Carry deoxygenated blood
What specific veins carry oxygenated blood?
Pulmonary Veins
Order of blood vessels
Artery -> Arteriole -> Capillaries -> Venules -> Vein
Myocardium
Cardiac muscle
Superior Vena Cava
Returns blood from head, neck, and arms
Inferior Vena Cava
Returns blood from the body inferior to the heart
Pulmonary Trunk
The only vessel that moves blood from the right ventricle
Pulmonary Artery
Carries deoxygenated blood to lungs to get oxygen
Pulmonary Veins
Carries oxygenated blood from lungs back to left atrium
Auricle
Pouch like extensions. Pulmonary trunk is in between these structures
Ligamentum Arteriosum
Blood vessel that is closed in adults
Atrium (R/L)
Upper “receiving” chambers of heart
