Is there a place in the center on the heart where blood dont touch?

Yes, in the center of the heart, there is a region known as the heart valves, specifically the atrioventricular and semilunar valves. These valves regulate blood flow between the heart's chambers and to the arteries but do not contain blood themselves. Additionally, the heart's conducting system, which includes the sinoatrial node and atrioventricular node, also exists in this central area and helps coordinate heartbeats without direct blood contact.
