Document Summary
Internal organs matured: optimal period of physical functioning, physical appearance, genetics, health maintenance practices. Skeletal system: peak bones mass achieved by both genders by 30 years-35. Following peak bone mass, rate of bone loss greater for women than men: skeletal growth ceases but bones able to replace/heal selves. Cardiovascular system: selective areas of arteries thicken, fat accumulates in arteries & forms soft plaques, plaques precursor to artherosclerosis, lifestyle risks associated with cardiovascular disease, cholesterol level, salt intake, alcohol consumption, blood pressure, stress, exercise, smoking. Respiratory: men"s lung function peaks at 25 years, women"s lung function peaks at 20 years, by 30, gradual loss of alveoli elasticity decreased vital capacity (vital capacity= volume of air) Integumentary: loses moisture after adolescence, drier & increasingly wrinkled with age, factors that influence skin agin, heredity, climate, cigarette smoking, sun exposure. Disadvantages: skin cancer: hormonal balance, general health. Dentician: wisdom teeth around 19-21 years of age.
