Arteries: away from heart
Components of CV system Correct Answers 1. Heart: central
pump

3. Blood: fluid contained within the CV system
Coronary sulcus Correct Answers encircles heart and marks
boundary between atria and ventricles
Describe the skeleton of the heart Correct Answers It is a plate
of fibrous connective tissue between atria and ventricles
