Do the atria Contract?
Sunday, December 27th, 2009Cooler asked:
If so, show me a detail medical reason for this phenonmenon. Why doesn’t the Atria have a valve to prevent back flow if the atria do contract. Where does the blood go? What is the mechanism of atrial contraction ?> Please give a most detailed as answer as possible. I need to proove this to a fellow classmate who refuses to believe the atria contract, he says its not possible because if the atria contract blood will flow back as there is no valve that sepeates the atra from the vena cavas.
