Soc15 Cardiovascular System Flashcards
3 Main Functions Of The Cardiovascular System
Help Blood Clot
Controls Body Temperature
Helps Transport Oxygen And Nutrients And Removes Carbon Dioxide
What is Vascular Shunting
Process that increases blood flow to active areas during exercise by diverting blood away from inactive areas which is achieved by vasodilation and vasoconstriction
What is Vasodilation
When veins swell up or dilate, widening of the internal diameter (lumen) of the blood vessel to allow increased blood flow.
What is Vasoconstriction
When veins shrink down narrowing of the internal diameter (lumen) of the blood vessel to decrease blood flow
What is Cardiovascular to do with
It is to do with heart,blood and blood vessels together
What is the Cardio-Respiratory System
the interaction of the heart and lungs to supply oxygen to musces during exercise
