Question

which statement explains blood pressure? blood pressure is highest in the veins near the heart. blood pressure is highest in the arteries near the heart. blood pressure is highest in the veins farthest away from the heart. blood pressure is highest in the arteries farthest away from the heart.

Explanation:

Blood pressure is the force exerted by blood on the walls of blood vessels. Arteries carry blood away from the heart. When the heart contracts (systole), it pumps blood into the arteries near the heart. The pressure is highest in these arteries as they receive the freshly - pumped blood directly from the heart. Veins carry blood back to the heart, and the pressure in veins is generally lower than in arteries. As blood moves through the arterial system and gets farther from the heart, the pressure decreases due to the resistance in the blood vessels and the energy loss from the pumping action.

Answer:

Blood pressure is highest in the arteries near the heart.
