As individuals age, one of the most prevalent vascular changes observed is the development of rigid peripheral blood vessels. This rigidity is due to various factors, including the accumulation of collagen, decreased elastin, and changes in smooth muscle function. As blood vessels become less elastic, they are unable to accommodate the pulsatile nature of blood flow as effectively, leading to increased systolic blood pressure. This increased rigidity contributes to the overall decrease in vascular compliance, which can further affect cardiovascular health and increase the risk of conditions such as hypertension.

While younger individuals typically have more elastic blood vessels that can expand and contract easily, the age-related changes lead to a stiffening of these vessels in older adults. This is a significant physiological phenomenon precisely because it influences the functioning of the cardiovascular system, showcasing the importance of understanding vascular health in geriatric assessments. The other options do not accurately reflect the common vascular changes seen in older adults, focusing instead on incorrect or less prevalent changes.
