What is the result of the flow of blood back into the atria when the ventricles contract?
A heart murmur is the result of the flow of blood back into the atria when the ventricles contract.
What are the things that are exchanged in organisms without circulatory systems?
In organisms without circulatory systems, gases, nutrients and wastes are exchanged by diffusion.
Which ventricle is thicker?
Since the left ventricle must pump blood to the whole body, its myocardium is much thicker than the myocardium in the right ventricle
What allows for exchange of nutrient and waste molecules across their thin walls?
Capillaries allow exchange of nutrient and waste molecules across their thin walls.
How much of the time is the heart in diastole?
The heart is in diastole about 50% of the time.
Do vertebrates have a circulatory system?
All vertebrates have a closed circulatory system.
