Blood Vessels Flashcards
Transport blood from the right ventricle of heart through lungs and back to the left atrium
Pulmonary vessels
Transport blood from left ventricle through all parts of the body and back to right atrium
Systemic vessels
Three main types of blood vessels
Arteries
Capillaries
Veins
Innermost later of blood vessel
Tunica intima
Middle layer of blood vessels
Tunica media
Outermost layer of blood vessels
Tunica Adventitia
Carry blood away from the heart
Arteries
Is artery oxygenated or deoxygenated?
Oxygenated
Classification of arteries
Elastic
Muscular
Arterioles
Arteries that have the largest diameter and have thickest walls
Elastic Arteries
Contraction of smooth muscle
Vasoconstriction
Relaxation of smooth muscles
Vasodilation
Decreases blood vessel diameter and blood flow
Vasoconstriction
Increased blood vessel diameter and blood flow
Vasodilation
Smallest artery
Arterioles
Transport blood from small arteries to capillaries
Arterioles
Where the diffusion or exhange of gases, substances, and other wastes products of occurs between the blood and tissue fluid
Capillaries
Smallest blood vessels
Capillaries
Carry blood toward the heart
Veins
Is veins oxygenated or deoxygenated?
Deoxygenated
Similar in shape to semilunar valves consisting of folds
Valves
How the blood flow in blood vessels
Arteries
Arterioles
Capillaries
Venules
Medium sized veins
Veins
Heart
Largest artery or blood vessels
Aorta
Examples of elastic arteries
Aorta
Pulmonary trunk
