Answer 1

Concisely describes the blood flow of a deoxygenated red blood cell through the heart

• Capillaries are the place where the blood is transferred from arteries into veins and separated as deoxygenated blood.
• The inferior vena cava receives the deoxygenated blood from lower parts of the body.
• The superior vena cava receives the deoxygenated blood from the head, neck, and upper extremities.
• Then the deoxygenated blood from superior and inferior vena cava goes through the right atrium.
• Then it enters into the right ventricle via tricuspid valve.
