Final answer:
A physiological change typically associated with aging is the decreased ability to smell and taste(option a). Aging affects the body's systems, causing changes in muscle mass, skin elasticity, and the functions of sensory and endocrine systems.
Step-by-step explanation:
An example of a physiological change typically associated with aging is the ability to smell and taste decreases(option a).
Aging affects several systems in our body, leading to pronounced changes in our physiological functions. The changes that occur in the digestive system, such as less sensitive taste buds and diseases that impact the gums and teeth, along with decreased salivation, can make eating less enjoyable. Similarly, the sensitivity of the senses, including smell and taste, declines notably after age 50, resulting in food that may seem bland and unappealing to older adults compared to their younger counterparts.
In addition to digestive and sensory changes, aging is associated with an overall decline in muscle mass, strength, and mobility. The structure and function of tissue also change with age, as cells, tissues, and organs undergo senescence, leading to thinner, drier skin with less elasticity, contributing to wrinkles and potentially higher blood pressure. Changes in endocrine glands such as the ovaries or anterior pituitary gland also alter hormonal balances that can contribute to changes in body composition and function. Hence, the decreased ability to smell and taste is a characteristic physiological change during the aging process.
