lo 3.7 - 3.8. what type of blood do the pulmonary arteries carry?
the pulmonary arteries carry low - oxygen blood from the right ventricle of the heart to the lungs.
the pulmonary arteries carry low - oxygen blood to the body from the right ventricle of the heart.
the pulmonary arteries carry high - oxygen blood from the right ventricle of the heart to the lungs.
the pulmonary arteries carry oxygen - rich blood from the left ventricle of the heart to the lungs.
the pulmonary veins carry low - oxygen blood from the right ventricle of the heart to the lungs.

Explanation:

The pulmonary arteries are responsible for transporting blood from the right ventricle of the heart. The blood in the right ventricle is low - oxygen (deoxygenated) as it has returned from the body. The destination of this blood is the lungs, where it will pick up oxygen.

• Option 2 is incorrect because the pulmonary arteries do not carry blood to the body; that is the role of the systemic arteries.
• Option 3 is incorrect as the blood in the right ventricle is not high - oxygen.
• Option 4 is incorrect because the pulmonary arteries are connected to the right ventricle, not the left ventricle.
• Option 5 is incorrect as it refers to pulmonary veins, which have a different function (carrying oxygenated blood from the lungs to the heart).

Answer:

The pulmonary arteries carry low - oxygen blood from the right ventricle of the heart to the lungs.
