Question

what does the carotid artery supply?
a deoxygenated blood to kidneys
b deoxygenated blood to liver
c oxygenated blood to brain
d oxygenated blood to the heart

Explanation:

Arteries carry oxygenated blood (except pulmonary arteries). The carotid arteries are major blood vessels in the neck that deliver oxygen-rich blood to the brain, face, and neck. Options a and b are incorrect because they reference deoxygenated blood (carried by veins) and incorrect organs. Option d is incorrect as the heart is supplied by coronary arteries, not carotid arteries.

Answer:

c. Oxygenated blood to brain
