Show the correct sequence of the path of blood flow through the pulmonary and sytemic circuits by placing the number of the part of the heart that receives oxygen poor blood from body tissues in the first blank, then continuing the sequence until you are back at the starting point. HINT: You will start AND end with the same part of the heart!

Please see answer in the explanation column section:

Explanation:

The path of blood flow through the pulmonary and systemic circuits  is given in this order starting from the Right atrium and ending at the same right atrium.

The four valve which would be seen in the path flow are responsible for preventing back flow of blood ensuring the right flow of blood in the pulmonary and systemic circuits. The right part of the heart( right Atrium) receives the oxygen poor blood from the body

 Right Atrium->Tricuspid valve->Right Vestibule->Pulmonary valve->Pulmonary arteries->Lungs->Pulmonary veins->Left Atrium->Bicuspid (Mitral) valve->Left ventricle->Aortic valve->Aorta->All the body.->Coronary artries->Superior vena cava(returns blood from head neck upper limbs and chest to the heart) and Inferior vena cava ( returns all blood under the diaphram tothe heart)-> Right atrium .
