SOC 15 CARDIOVASCULAR SYSTEM Flashcards
(6 cards)
What makes up the
cardiovascular system?
The cardiovascular system is formed by our
heart and blood vessels. Cardio means the
heart and vascular mean blood vessels.
Cardio-respiratory system:
the interaction of the heart and lungs to supply oxygen to muscles during exercise.
Cardiovascular:
to do with the heart, blood and blood vessels together
Vasodilation:
when veins swell up or dilate; widening of the internal diameter (lumen) of the blood vessel to allow increased blood flow.
Vasoconstriction:
when veins shrink down; narrowing of the internal diameter (lumen) of the blood vessel to decrease blood flow.
Vascular shunting:
process that increases blood flow to active areas during exercise by diverting blood away from inactive areas; achieved by vasodilation and vasoconstriction.
