condition in which all of the body's systems are workinng their best
physical and chemical processes
ten systems in the body
- circulatory or cardiovascular
- immune and lymphatic
body sysems are made up of...
organs are made up of
tissues are made up of groups of cells that perform a similar task. give example
the heart is one of the organs in the cirulatory system. it is made of tissues and cells.
Describe the integumentary system
- layers and layers of skin - largest organ in the body.
- prevents injury to intenal organs
- prevents loss of too much water
- sweat glands in skin secrete sweat to cool the body
- sebaceous glands secrete oil (sebum) to lubicate skin
- there are hair follicals, tiny blood vessels (capillaries and tiny nerve endings
Blood vessels ... when the outside temperature is too high. which does it do to the body surface?
dilate (widen) to bring more blood to the body surface to cool it off.
blood vessels... when outside temperature is too cold.which does what to the body surface?
- which reduces the amount of blood in superficial layers of the skin to retain heat for the more important systems to function
Normal changes of aging in skin:
- tinner, drier, fragile and easily damaged
- less elasticity
- protective fatty tissue is lost ( makes them colder)
- hair thins and may turn grey
- wrinkles and brown spots (liver spots)
- nails are hard and more brittle
- reduction of oil production from sebaceous glands (dry skin)
NOT normal changes in aging of skin:
- pale, white or reddened or purple areas blisters or bruises
- flaking skin, excessivly dry
- swelling, fluid secretion from skin
- scalp or hair changes ( not including color)
- in ebony skin, orange peel look and crust like areas that might be covering a tissue break.
Musculoskeletal system includes:
and gives the body..
muscles, bones, ligamenrs, tendons, and cartilage that give the body structure
how many bones are in the human body
lack of exercise can result in:
- low self-esteem, depression, pneumonia, and urinary tract infections
- constipation, blood clcots and dull senses, muscle atrophy or contractures
muscle wastes away decreses in size and becomes weak
muscle shortens, becomes inflexible and 'freezes' in position. causes disability of limb
you can help contracture of a muscle by introducing ROM activites to extend and flex joints to increas circulation of blood, oxygen and nutrients and improves muscle tone
Normal changes of muslce aging:
- weaken and lose of tone in muslcebody movement slows
- bones are less dense (brittle and easily breakable)
- joints stiffen and become painful
- height is gradually lost
NOT normal changes of muscle aging:
- changes in ability to perfomr routine movements and actvities
- changes in ability to prefom ROM
- pain in movement
- swelling of joitns
- white shiny red or warm areas over a joint
- aches and pains
Arthrities refers to...
- inflamation (swelling)
- stiffness pain and decreased mobility.
arthritis can be the result of...
aging, injury or an autoimmune illness
autoimmune illness causes...
immune system to attack normal tissue int he body
types of arthritis
- rheumatoid arthritis
- type of arthritis that attacks elderly (mostly) weight bearing joints are usually affected. causes brittle porus bones
- pain and stiffness increases in cold or damp weather
- Due to a lack of calcium in bones, alchohol or lack of exercise
- more common in women after menopause
- Excersie calcium and regular enercize can can prevent.
- Signs include stooped posture and becoming shorter
- occurs in people of all ages
- joints become red, swollen, and very painful. movement is restricted, fever fatigue and weight loss are also symptoms
Treatment of arthritis
- anti-inflammmatory medications (asprin or ibuprofen)
- applications of heat to reduce swelling and pain
- ROM and exercise
- diet to maintain a healthy weight
What to watch for with people with arthritis
- stomach irritation or heartburn caused by ibuprofen or asprin
- Encourage activity
- Encourage idepentant ADLs
- encourage easy clothing to put on and take off
Most common fractures
hip elbows legs arms
many fractured hips need...
Total hip replacment rplaces...
- head of the long bone of the leg (femur) where it joins the hip.
- fx that doesn't heal properly
- weakened hip due to ageing
- causes extreme pain
partial weight bearing
Never do what on the hip replacement side of a person
don't let the resident sit ... after a hip replacement
sit with legs crossed or toes turned inward.
When transferring from bed and helping ambulate where do you stand?
on the UNAFFECTED side
Knee replacement is the surgical insertion of...to reduce...
- a prosthetic knee
- to reduce pain?
Recovery is shorter for hip or knee replacement?
Nervous System includes:
Brain, Spinal cord, Nerves
normal changes in nervous system
- slow responses and relexes
- sensitivity of nerve endings in skin decreses
- some short term memory loss
NOT normal changes in nervous system
- fatigue or pain with movement or exercise
- shaking or trembling
- inability to speak clearly
- inability to move one side of the body
- disturbances or changes in visio or hearing
- changes in eating patterns and or fluid intake
- difficulty swallowing
- bowel and bladder changes
- depression or mood changes memory loss or confusion
- violent behavior
- any unusual or unexplained change in behavior
- decreaed ability to perform ADLs
CVA stands for and is
- cerebrovascular accident and is a stroke
- blood supply to the brain is cut off suddenly by a clot or a ruptured blood vessel.
Paralysis on one side of the body
weakness on one side of the body
Inability to speak or speak clearly
inabiilty to understnad spken or written words
Stokes can cause:
- expressive aphasia
- receptive aphasia
- loass of sensations such as temp or touch
- poor judment
- memory loss loss of cognitive abilities
- ignore affected side
- laughing or crying without reason(inappropriate) Emotional ilability
- dysphagia (diff swallowing)
For strokes, symptoms depend on which side of the brain the CVA affected. weakness on the right side of the body shows the ...side of the brain was affected
when a pt has a stroke always use ...to make sure they stay safe
Parkinson's Disease is a ... disease
Parkinsons disease causes what to degenerate? and affects what?
a section of the brain. affects muscles causing them to become stiff
- stooped posture, shuffling gait (walk), pill-rolling(thumb and index finer move in circular motion when brought togeather)
- tremors occuring making bathing and eating difficult.
how to help someone with parkinson's
avoid falls, ADLs, ROM, encourage self-care
MS stands for
MS is a... disease
MS affects what system?
MS tears down what?
the protective covering for nerves, spinal cord, and white matter of the brain over time
MS tears down parts of the body so that what doesn't function properly
nerves, transmittors and receptors don't fuction in a normal way.
When do ppl usually get diagnosed with MS
in early twenties to thirties
Symptoms of MS
blurred vision, fatigue tremors, poor balance, trouble walkin, weakness numbness tinling incontinence and behavior changes
how to assist someone with MS

- erections may occur
- constipation is likely - encourage fluids
- urinary catheter may be used - keep clean!
- fatigue is common, offer rest periods
- couging and shallow breathing can lead to pneumonia, take DEEP breaths
Normal Changes in NERVOUS SYSTEM through aging

- complaints of pain in eyes or ears
Vision probelms include conditions like..
cataracts glaucoma and blinness
Cataracs is when..
- lens of the eye becom cloudy preventing light from entering the eye

High blood pressure can lead to...
CVA, heart attack, kidney disease, blindness
Tx of high blood pressure
- Diuretics (drugs that reduce fluid in the body)
- med to lower cholesterol
- may have special diet, low fat low sodium
- may have exercise programs
CAD stands for..
Coronary Artery Disease
- blood vessels in the coronary arteries narrow reducing supply of blood to heart muscle and deprives it of oxygen and nutrients. Fatty deposits block the artery, muscle that was suplied by theblood vesel dies.
