What are some causes of cardiovascular diseases that are controllable
Obesity
High cholesterol
Tobacco use
Being poor
Excessive alcohol
What is an Innate Immune system
The immune system present at birth, that includes physical barriers, chemical barriers (ex.stomach acid, saliva), and white blood cells
What is an Adaptive Immune System
An immune system that adapts over time through exposure to certain “pathogens”. B or T cells are activated through immunological memory and builds up resistance (vaccines)
What are 3 facts about the Innate and Adaptive immune systems and aging
1) Both innate and adaptive immune systems decline with age
2) infectious diseases account for roughly 1/3 of death in people ages 65+
3) Hospital/long-term care stays can increase the risk for exposure to infections
What disease causes trouble for your body to produce insulin or can’t properly use the insulin it produces, resulting in difficulty regulating blood sugars
Diabetes Mellitus
What is the difference between type 1 and type 2 diabetes mellitus
Type 1 = when your insulin defendant and usually develops earlier in life (its harder to tell if you need insulin)
Type 2 = Develops in adulthood and is managed through diet

Biological = changes in glucose metabolism
Psychological = Sedentary lifestyle, depression and stress
Social = Habitual eating patters, lack of education (low understanding), low economic resources
What is the function for Thyroid Hormones
To control the Basal Metabolic Rate (BMR)

Due to loss of bone mineral in the vertebrae
What disease is characterized by a decrease in the density and quality of the bone?
Osteoporosis
What are 3 changes in weight as we age?
1) Fat free mass (FFM) decreases (because bone and muscle mass decreases)
2) Body mass index (BMI) increases from the 20s to 50s
What percent of our weight is lost by 80?
50%
Progressive declines in muscle mass and strength begins in ones ___s and ___s but can be prevented by ________.
30s and 40s, exercise
What type of musculoskeletal system disease thinns the cartilage of bone joints and causes them to rub together (can happen to one part of the body)
Osteoarthritis
What type of musculoskeletal system disease causes bone erosion and swelling of the synovial membrane (happens to either sides of the body)
Rheumatoid Arthritis
Changes in the _________ system impacts balance
Vestibular system
What are some age related changes in Neurons
- number of neurons declines
- number and size of dendrites decreases
- tangles develop in axon fibers
- synapses decrease
What is Menopause?
A reduction in estrogen/progesterone and the onset of fertility that occurs mid to late 40s in women
What are some characteristics of Menopause
Hot flashes
Insomnia
Vaginal dryness
Mood swings
