✔✔What are the functions of the cardiovascular system? - ✔✔1 . Circulation of blood
A . Blood transports
Oxygen and carbon dioxide
Metabolic Waste
Chemical Messengers
(Hormones)
2. Maintaining core temperature.
✔✔Describe Prime mover and Antagonist - ✔✔Prime mover/ Agonist: The muscle that
provides most movement tension.
Antagonist: The muscle that provides the opposite movement.
EX: Bicep curl
Agonist- Bicep
Antagonist- Tricep
✔✔Describe sensory Neurons - ✔✔Sensory neurons carry information to the central
nervous system.
✔✔Describe motor neurons - ✔✔Carry info to Peripheral nervous system to respond
A. some motor neurons control only a few muscle fibers , such as in the hand where
dexterity is required.
✔✔What are motor units? - ✔✔A single neuron and the fibers it controls are called
motor units
✔✔What are Slow twitch muscles used for ? - ✔✔Better for endurance because they
use oxygen better and resist fatigue.
They also,
1.have more mitochondria 2.contract slowly and produce less force
3. work aerobically.
✔✔What are fast twitch muscles used for? - ✔✔Fast twitch muscles are best for intense
bursts of activity.
They also ,
1.Produce ATP more quickly
2.Contract quickly and produce a lot of force
, ✔✔What are the planes of movement? - ✔✔Frontal Plane : Hip abduction , lat raise
Sagital Plane : Bicep curl , leg extension
Transverse Plane : Twist or rotation
✔✔Describe stroke volume - ✔✔The amount of blood that the left ventricle ejects in one
beat
* A healthier person will have a higher stroke volume.
✔✔What are the factors related to muscle strength? - ✔✔1.Muscle size
2.Muscle length
3.Neural control
4.Speed of contraction
✔✔What are SMART goals? - ✔✔Specific : Lose 25 Pounds
Measurable: How will we measure change? (Pounds)
Attainable: Plan of execution( 2 x week cardio 2 x week resistance training , and healthy
nutrition )
Realistic : How much change can you expect on a weekly basis ? ( 1 pound of fat a
week)
Time sensitive : How long will it take? (25 weeks or whatever it equates to)
✔✔What are the subcategories of ventilation? (cardio respiratory system) -
✔✔Inspiration: Diaphragm contracts and moves down , rib cage moves upwards and
outwards
Expiration: Muscles relax , lungs recoil
Mixed air: (air we breathe) nitrogen 78% oxygen 21% , carbon dioxide.
✔✔What is catabolic metabolism? - ✔✔Break down of molecules for energy
✔✔What is Anabolic metabolism? - ✔✔Building molecules for energy
✔✔What is blood pressure the result of? - ✔✔The pressure against arterial walls
created by blood being pumped out of the ventricle.
✔✔What is a healthy Resting blood pressure? - ✔✔120 systolic ( as the heart contracts)
