Body System Function Short-Term Effects Long-Term Effects Other Effects Key Terms
Cardiac output ­ amount of
Resting heart rate blood ejected from heart in 1
Diet ­ cholesterol in minute
Supplies the body Faster, deeper decreases arteries, more chance Stroke volume ­ volume of
blood pumped out of each
with oxygen and breathing Increase in stroke of strokes, high BP ventricle during one contraction
HDL ­ high density, more
nutrients Increase in body volume Drugs ­ increase in BP protein foods, move cholesterol
Cardiovascular away from arteries, usually
Decreased blood Stress ­ increase in BP vegetables and whole grains
System Removes waste temperature LDL ­ low density, consists of fat
pressure Alcohol ­ HDL better and causes cholesterol
products such as Sweating for arteries
Sedentary lifestyle -
carbon dioxide Muscle ache Healthy veins and Systolic ­ maximum pressure
Smoking ­ blocked in the arteries when heart
arteries arteries and high BP contracts
Diastolic ­ pressure in
arteries when heart relaxes
Inhale oxygen, Increased breathing Smoking ­ carbon
Increases lung
exhale carbon rate monoxide replaces Vital capacity ­ the greatest
efficiency amount of air that can be inhaled
Respiratory dioxide in order to Oxygen debt when oxygen in red blood or exhaled by the lungs
System More alveoli cells, damages alveoli Tidal volume ­ amount of air
respire performing inhaled and exhaled with each
Increase vital capacityso vital capacity normal breath
anaerobically decreases
Rest ­ allows muscles
Increase in muscle size to grow and repair Isometric ­ where muscles
relax/contract with no movement
Soft tissue injuries Diet ­ protein builds Isotonic ­ where muscles
Increase in and repairs muscles
relax/contract and movement is
Muscular Driving force Increase in strength
Voluntary ­ muscles you
oxygen demand Drugs ­ anabolic control
System behind movement
Lactic acid builds Increase in muscle steroids enhance Involuntary ­ muscles you
don't control, e.g. the heart
endurance muscle growth and Antagonistic pairs ­ one
muscle relaxes (antagonist) and
allow one to perform one contracts (agonist)
longer and harder

Here's a taster:

Injury More bone density
Osteoporosis ­ disease
Support Open (sticking out) Less risk of Diet ­ calcium where bones are weak
Ligaments ­ connect bone to
Movement Closed (bruising/swelling) osteoporosis increases bone bone
Skeletal System Tendons ­ connect bone to
Complicated (vital organ) Stronger ligaments development and
Protection makes them stronger
Greenstick (young people Long term injury
Cartilage ­ cushioning
between bones
flexible bones)…read more
