Question

Based on the information given below, which blood vessels are correctly represented by X, Y, and Z?
X Transport blood to the heart.
Y Unite into venules to form veins.
Z Transport blood away from the heart.

• A. X - Capillaries, Y - Veins, Z - Arteries
• B. X - Arteries, Y - Veins, Z - Capillaries
• C. X - Veins, Y - Capillaries, Z - Arteries
• D. X - Capillaries, Y - Arteries, Z - Veins

Answer 1

The correct option is C X - Veins, Y - Capillaries, Z - Arteries

All veins carry deoxygenated blood to the heart except the pulmonary veins.

The arteries divide to form arterioles that further divide to form capillaries. These capillaries supply oxygen-rich blood to the cells. The capillaries leave the cell to form venules that unite to form veins.

All arteries carry oxygenated blood away from the heart except the pulmonary arteries. Thus the correct answer is option C.
