-
1
-
2
-
3
-
4
Correct Answer
A. 2Explanation
In a typical case, there are two pulmonary veins that travel to each lung. The pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the heart. Each lung receives blood from two pulmonary veins, one from the superior lobe and one from the inferior lobe. This allows for efficient oxygenation of the blood and transportation of oxygen to the rest of the body.Rate this question:

The descending aorta is a continuation of which vessel?
-
Ascending aorta
-
Arch of the aorta
-
Right subclavian artery
Correct Answer
A. Arch of the aortaExplanation
The descending aorta is a continuation of the arch of the aorta. After the ascending aorta and the arch of the aorta, the descending aorta begins and continues downward, supplying oxygenated blood to the rest of the body. The right subclavian artery is a branch of the aorta, but it does not directly connect to the descending aorta.Rate this question:
