Solution
The factors that contribute to the typical increase in blood pressure with aging are:
-
Cross-linking of elastic fibers in the arteries: As we age, the elastic fibers in our arteries can become cross-linked. This reduces the elasticity of the arteries, making them stiffer. When the arteries are stiff, they can't expand as easily when the heart pumps blood through them, which can lead to an increase in blood pressure.
-
Atherosclerosis: This is a condition where plaque builds up in the arteries, narrowing them and making it harder for blood to flow through. This can also increase blood pressure.
-
Weakening of the middle layer of the artery: The middle layer of the artery, known as the media, can weaken with age. This can cause the artery to dilate, or widen, which can increase blood pressure.
The increased diameter of the artery lumen does not typically contribute to an increase in blood pressure with aging. In fact, a larger lumen would generally allow for easier blood flow and could potentially decrease blood pressure. However, this is not typically what happens with aging. Instead, the lumen often becomes narrower due to conditions like atherosclerosis.
