How Does Aging Affect Organ Systems Histologically?
Aging affects various organ systems in distinct ways. In the cardiovascular system, there is an accumulation of collagen in the walls of blood vessels, leading to reduced elasticity and increased stiffness. The respiratory system shows a decline in the number of alveoli and thickening of alveolar walls, reducing gas exchange efficiency. In the nervous system, there is a loss of neurons and synapses, leading to cognitive decline and slower reflexes.
