Biology of Aging presents the biological principles that have led to a new understanding of the causes of aging and describes how these basic principles help one to understand the human experience of biological aging, longevity, and age-related disease. Intended for undergraduate biology students, it describes how the rate of biological aging is measured; explores the mechanisms underlying cellular aging; discusses the genetic pathways that affect longevity in various organisms; outlines the normal age-related changes and the functional decline that occurs in physiological systems over the lifespan; and considers the implications of modulating the rate of aging and longevity. The book also includes end-of-chapter discussion questions to help students assess their knowledge of the material.The physiological response of the heart to an increased demand for systemic flow does change with age and might ... Since arteries help to regulate blood flow and pressure in direct proportion to their ability to expand and contract, a decrease in distensibility will affect blood flow and pressure. ... Most individuals over the age of 60 have some buildup of arterial plaques, fatty deposits inside arterial walls.
