Answer Details
Blood pressure is higher in the arteries as a result of contraction and relaxation. Arteries are the blood vessels that carry oxygenated blood away from the heart to other parts of the body. The heart pumps blood into the arteries, and the contraction of the heart muscles forces blood into the arteries, creating pressure in them. This pressure is known as systolic blood pressure. When the heart relaxes, the pressure in the arteries decreases, which is known as diastolic blood pressure. The alternating contraction and relaxation of the heart muscles along with the elasticity of the arterial walls maintain the blood pressure in the arteries. This pressure is necessary for proper circulation of blood and delivery of oxygen and nutrients to the body tissues.
