Question
Which of the following is generally true about the path of blood flow through the heart?A.The right ventricle contracts to propel blood to all body tissues except the lungs.B.The left ventricle pumps blood into the left atrium.C.The aorta receives blood from the left ventricle.D.The right atrium receives blood from the pulmonary veins.
Solution
The statement that is generally true about the path of blood flow through the heart is C. The aorta receives blood from the left ventricle.
Here's why:
A. The right ventricle contracts to propel blood to the lungs, not all body tissues except the lungs. This is part of the pulmonary circulation.
B. The left ventricle pumps blood into the aorta, not the left atrium. The left atrium receives blood from the pulmonary veins.
C. The aorta does indeed receive blood from the left ventricle. This is part of the systemic circulation where oxygenated blood is pumped from the heart to the rest of the body.
D. The right atrium receives blood from the body via the superior and inferior vena cava, not from the pulmonary veins. The pulmonary veins carry oxygenated blood from the lungs to the left atrium.
