Document Summary
Recall: cells respond to stress through: hypertrophy increase in the size of a cell accompanied by an augmented functional capacity. Increased functional demand: ex myocardial hypertrophy in hypertension, muscle hypertrophy after weightlifting, hormonal hypertrophy, ex sex organs at puberty, atrophy decrease in size and function of a cell, causes, decreased workload, decreased blood supply, aging.
