Answer:
The correct pathway for oxygen-poor blood is right atrium → right ventricle → pulmonary artery → lungs (first option).
Explanation:
Unoxygenated or oxygen-poor blood is that which comes from tissues that have exchanged O₂ for CO₂. The venous return is in charge of taking that blood to the heart and then to the lungs.
- Oxygen-poor blood reaches the <u>right atrium</u> from the vena cava.
- From the atrium the blood passes to the <u>right ventricle</u> through the tricuspid valve.
- The <u>right ventricle pumps the blood to the lungs</u> through the pulmonary arteries, the only arteries that carry venous blood.
Once in the lungs, the blood exchanges CO₂ for O₂, returning to the heart through the pulmonary veins.
The other options are not correct because:
- <em><u>Left atrium, left ventricle, aorta, body</u></em><em> corresponds to the flow of oxygenated blood that comes from the lungs and is pumped to the entire body.</em>
- <em><u>Left atrium, right atrium, left ventricle, right ventricle</u></em><em> not correspond to the order in which blood flows through the heart.</em>
- <em><u>Right ventricle, right atrium, pulmonary veins, lungs</u></em><em> not correspond to the flow of oxygen-poor blood.</em>
