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.
What are the 3 main functions of the cardiovascular system
1.transports oxygen,carbon dioxide and nutrients
2.it helps clot blood
3.it controls the body temperature
What is vascular shunting
Process that increases blood flow to active areas during exercise
by diverting blood away from inactive areas; achieved by
vasodilation and vasoconstriction.
What is the cardio respiratory system
the interaction of the heart and lungs to supply oxygen to muscles during exercise.
What is cardiovascular
to do with the heart, blood and blood vessels together.
What is vasolidation
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.
