Question

In order for the blood to flow right atrium to left ventricle in mammalian heart, it must flow through

Answer 1

Answer:

Blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricles are full, the mitral valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract (squeeze).

Answer 2

Answer: The deoxygenated blood moves from the right ventricle to the lungs through the pulmonary artery. The oxygenated blood from lungs flows back to the left auricle through pulmonary vein. Then, by auricular contraction, oxygenated blood reaches the left ventricle.
