Question

Rearrange the given words in the correct logical sequence.Pulmonary veins, left auricle, pulmonary artery, lungs, right ventricle​

Answer 1

Answer:

Right atrium → right ventricle → left atrium → left ventricle.

Explanation:

Both vena cava passes the deoxygenated blood to the right atrium. Blood from right atrium enters right ventricle and pulmonary arteries carry deoxygenated blood from right ventricle to lungs for oxygenation.

Answer 2

Answer:

Right ventricle;Pulmonary artery;Lungs;

Pulmonary veins;Left auricle,

Explanation:

This is according to the circuit in which the blood flows through the heart.

1) The deoxygenated blood comes through the

Superior vena cava ( upper part of the body )

Inferior vena cava ( lower part of the body )

into the Right atrium .

2) The right atrium creates pressure forcing the deoxygenated blood to go through the Tricuspid valve into the Right ventricle .

3) Now the pressure created by the right ventricle pushes the deoxygenated blood into the pulmonary artery through the semilunar valve to the lung for purification .

4) After purification of the deoxygenated blood in the lungs the oxygenated blood comes to the

left atrium through the pulmonary veins .

5) Again, the left atrium sends the purified blood into the left ventricle through the mitral valve .

6) The left ventricle which has a thicker muscular wall than the right ventricle sends the oxygenated blood through the aorta to all over the body .

This circut will continue.
