Question

Trace the sequencial path of blood in human heart

Answer 1

Answer: L.Auricle - L.Ventricle - P.Artery - Lungs - P.Veins - R.Auricle - R.Ventricle - Aorta - Body Tissues

Explanation:

De-oxygenated  blood flows from the right auricle into the right ventricle through the tricuspid valve. Then the blood flows through the pulmonary artery towards the lungs for oxygenation. Then oxygenated blood comes to the left auricle of the heart and flows down to the left ventricle of the heart through the bicuspid valve. Then the oxygenated blood flows through aorta to all the parts of the body.
