👉 Interventricular is a medical term used to describe the process of blood flow in the heart. It refers to the exchange of oxygenated blood from the right ventricle (right atrium) to the left ventricle (left atrium), which then returns back into the body through the pulmonary veins and veins, returning the blood back to the right atrium for pumping again. Interventricular is a key process in the heart's ability to deliver oxygenated blood throughout the body.
