Which chamber of the heart primarily forms the anterior surface?

Left atrium
Left ventricle
Right atrium
Right ventricle

The correct answer is: Right ventricle

The right ventricle is primarily responsible for forming the anterior surface of the heart. This chamber pumps deoxygenated blood to the lungs via the pulmonary arteries, and its position is oriented towards the front of the thoracic cavity. This anatomical placement allows the right ventricle to be more prominent on the anterior (front) part of the heart, especially when viewed from the front of the body. The left atrium, while critical for receiving oxygenated blood, is located more posteriorly and does not contribute significantly to the anterior surface. The left ventricle, which is larger and more muscular due to its role in pumping oxygenated blood throughout the body, also has a more posterior location relative to the front of the heart. The right atrium is located to the right and behind the right ventricle, making it less prominent on the anterior surface than the right ventricle. Hence, when considering the structure and position of the heart's chambers, the right ventricle is the primary contributor to the heart's anterior surface.
