Question

The circulatory system keeps the body and its tissues continuously oxygenated. It does this by having
A) veins to carry both oxygenated blood to the tissues and deoxygenated blood to the lungs.
B) arteries to carry both oxygenated blood to the tissues and deoxygenated blood to the lungs.
C) arteries to carry oxygenated blood to the tissues and veins to carry deoxygenated blood from the tissues to the lungs.
D) veins to carry oxygenated blood to the tissues and arteries to carry deoxygenated blood from the tissues to the lungs.

Answer 1

C) arteries to carry oxygenated blood to the tissues and veins to carry deoxygenated blood from the tissues to the lungs. 

Answer 2

C would make sense because the arteries carry blood away from the heart and veins carry toward it and your lungs will expel the deoxygenated blood from your body
