Question

11.1.4 quiz: respiration and circulation
question 3 of 10
a structure in the shoulder of a human is found to carry oxygen - rich red blood cells. what else is most likely true about this structure?
a. it is an artery with hypertension.
b. it contains a superior vena cava.
c. it also carries blood rich in carbon dioxide.
d. it carries blood toward the fingers.

Explanation:

Arteries carry oxygen - rich blood away from the heart. A structure in the shoulder carrying oxygen - rich red blood cells is likely an artery that would carry blood towards the fingers as part of the systemic circulation. Option A mentions hypertension which isn't necessarily true just based on it being an artery. The superior vena cava is not in the shoulder and carries deoxygenated blood to the heart, so B is incorrect. Oxygen - rich blood is being carried away from the heart and towards the fingers.

Answer:

D. It carries blood toward the fingers.
