WitrynaDuring systole, the tricuspid valve closes and the pulmonary valve opens, allowing the blood to enter pulmonary circulation. Newly oxygenated blood enters the left aorta (red arrow), where it passes through the mitral valve to reach the left ventricle. WitrynaThe open mitral valve allows blood in the atrium (accumulated during atrial diastole) to flow into the ventricle (see graphic at top). Likewise, the same phenomenon runs simultaneously in the right ventricle and …
