    Summary Introduction

    Introduction:

    The complex circulatory system has divided into three divisions the systemic circuit, the pulmonary circuit, and the coronary circuit. In coronary circulation, the heart receives blood directly from the aorta derive from the heart while in the pulmonary and systemic circulation, the heart propels blood to the lungs or remaining part of the body.

    Answer to Problem 1VCQ

    Correct answer:

    The correct answer is option (c) Blood in the pulmonary artery is deoxygenated.

    Explanation of Solution

    Explanation/justification for the correct answer:

    Option (c) blood in the pulmonary artery is deoxygenated. Arteries typically carry oxygenated blood, except pulmonary arteries that taken up deoxygenated blood from the right ventricles, and then carried to the lungs for oxygenation. So, the correct answer is option (c).

    Explanation for the incorrect answer:

    Option (a) blood in the pulmonary vein is deoxygenated. The pulmonary veins carry the oxygenated blood from the lungs to the left atrium of the heart. So, this is an incorrect option.

    Option (b) blood in the inferior vena cava is deoxygenated. Superior vena cava takes up deoxygenated blood from the brain and arms while inferior vena cava carries blood from the lower organs and legs to the right atrium. So, this is an incorrect answer.

    Option (d) blood in the aorta is oxygenated. The blood gets pumped into the left ventricle through the bicuspid valve or mitral valve and then passes to the aorta, which further circulates oxygenated blood to the organs and muscles of the body. So, this is an incorrect answer.

    Conclusion

    The statement blood in the pulmonary artery is deoxygenated is false. Hence, the correct answer is option (c) blood in the pulmonary artery is deoxygenated.

    Which of the following statements about the circulatory system is false? A. Blood in the aorta is oxygenated. B. Blood in the pulmonary artery is deoxygenated. C. Blood in the inferior vena cava is deoxygenated. D. Blood in the pulmonary vein is deoxygenated.
    Which of the following is NOT a part of all circulatory systems?   1.something to cause force/pressure 2.vessels 3.a fluid that moves throughout the body 4.blood
    Which statement below best explains why valves are necessary in the veins but not in the arteries? Venous valves prevent the backflow of blood into the ventricles. Blood flows in both directions through the arteries, but in the veins blood must flow in only one direction. Valves are found in arteries, not in veins. Blood in the arteries is moved forward by the pumping of the heart, but the veins feel very little of this forward push.
