The right ventricle is a key chamber in the heart, playing a crucial role in the pulmonary circulation. It is responsible for receiving deoxygenated blood from the body via the right atrium and then pumping it into the lungs through the pulmonary artery. Structurally, the right ventricle differs from the left ventricle; it has thinner walls and a crescent-like shape, reflecting its lower pressure workload than the left ventricle. The right ventricle’s interior is characterized by trabeculae carneae, muscular ridges, the tricuspid valve at the entrance, and the pulmonary valve at the exit. Its efficient functioning is vital for maintaining the balance of oxygen supply and carbon dioxide removal from the body. Disorders of the right ventricle, such as right ventricular hypertrophy or right heart failure, can significantly impact overall cardiovascular health and are essential considerations in cardiac diagnostics and treatment.
