Question
A person has a laceration to the right arm, and it is spurting bright red blood. The blood vessel is: a. The artery. b. The vein. c. The capillary.d. Venous.
Solution
The correct answer is a. The artery. The reason is that arteries carry oxygenated blood away from the heart to the body, and this blood is typically bright red. The pressure from the heart pumping causes the blood to spurt out when an artery is cut. Veins, on the other hand, carry deoxygenated blood from the body back to the heart and this blood is darker in color. Capillaries are tiny blood vessels where oxygen and nutrients are exchanged between blood and tissues, and venous refers to veins or the venous system.
