Do the ventricles contract at the apex or at the base of the heart?

Not really sure what you mean by the base, the ventricles contract from the Apex (which is at the bottom) upwards.

How does the heart stop blood from flowing the wrong way when the heart muscle contracts?
It has valves. The TRICUSPID valve between the right atrium and right ventricle and the BICUSPID valve between the left atrium and left ventricle. These valves open as the atria contract and close as the atria relax. The heart also has two SEMI-LUNAR valves at the base of the pulmonary artery and the aorta to prevent back flow from the arteries too. They open as the ventricles contract and close as the ventricles relax. Hope this helps :) Kim Walsh x

The heart is approximately conical in shape. It is well tilted that its apex is directed forwards, downwards and to the left and the base directed upwards and backwards. The apex is mainly formed by the left ventricle while the base is mainly posterior part of left atrium.
