Final answer:
Thermoregulation in older adults involves cardiovascular, metabolic, neural, and thermoregulatory adaptations to regulate body temperature.
Step-by-step explanation:
Thermoregulation in older adults involves several adaptations including cardiovascular, metabolic, neural, and thermoregulatory adaptations. Cardiovascular adaptations include vasodilation and vasoconstriction to regulate blood flow and heat transfer. Metabolic adaptations involve the use of waste heat from muscle contractions and the presence of brown fat. Neural adaptations center in the hypothalamus of the brain and control temperature through reflexes.
