Question

The correct pathway of movement of gases in the body is

• A. Oxygen from alveoli – pulmonary vein – left atrium – left ventricle – systemic arteries – tissues – carbon dioxide from tissues – systemic veins – right atrium – right ventricle – pulmonary artery – alveoli.
• B. Oxygen from alveoli – pulmonary artery – left atrium – left ventricle – systemic arteries – tissues – carbon dioxide from tissues – systemic veins – right atrium – right ventricle – pulmonary vein – alveoli.
• C. Oxygen from alveoli – pulmonary vein – left atrium – left ventricle – systemic veins – tissues – carbon dioxide from tissues – systemic arteries – right atrium – right ventricle – pulmonary artery – alveoli.
• D. Oxygen from alveoli – pulmonary vein – right atrium – right ventricle – systemic arteries – tissues – carbon dioxide from tissues – systemic veins – left atrium – left ventricle – pulmonary artery – alveoli

Answer 1

The correct option is A

Oxygen from alveoli – pulmonary vein – left atrium – left ventricle – systemic arteries – tissues – carbon dioxide from tissues – systemic veins – right atrium – right ventricle – pulmonary artery – alveoli.

The correct pathway of movement of gases in the body is:

Oxygen from alveoli –> pulmonary vein –> left atrium –> left ventricle –> systemic arteries –> tissues –> carbon dioxide from tissues –>systemic veins –> right atrium –> right ventricle –> pulmonary artery –> alveoli.
