NASM CPT CH.3 (video notes plus NASM study guide) Flashcards
Cardiorespiratory system’s function
- aids in performance and recovery
- delivers oxygen to the tissues and removes waste from them too
cardio system is made up of
heart and blood vessels
respiratory system is made up of
trachea, bronchi, alveoli, and lungs
top chambers of the heart
atrium
lower chambers of the heart
ventricles
oxygenated blood moves into the _________
left atrium and down into the left ventricle where it’s pumped out to the lungs to get re-oxygenated
the ___________ receives de-oxygenated blood from the rest of the body
right atrium
it then moves to the right ventricle and to the lungs to get re-oxygenated
total amount of blood pumped out with each contraction
stroke volume
average stroke volume
77 ml
average heart rate
70-80bpm
cardiac output
- volume of blood pumped out per minute
- HR x stroke volume
3 functions of blood
transport, regulate and protect
Blood Transports
oxygen to nutrients and tissues, waste removal from tissues, hormones to organs and tissues, heat
Blood Regulates
temperature and acid balance
If you sprint, what muscle aids in breathing?
Pec Minor
Respiratory System
gets oxygen to the lungs and removes carbon dioxide
regular breathing involves what muscles?
diaphragm and external intercostals
forced/dysfunctional breathing involves what muscles?
scalenes, pec minor
can lead to headaches and anxiety
Arterioles branch out into
capillaries
Blood protects by
clotting and fighting disease
the inferior chamber of the heart that receives blood from its corresponding atrium and in turn forces blood into the arteries
ventricles
a system of the body composed of the cardiovascular and respiratory systems
cardiorespiratory system
a hollow muscular organ that pumps circulation of blood throughout the body by means of rhythmic contraction
heart
a system of the body composed of the heart, blood and blood vessels
cardiovascular system
the superior chamber of the heart that receives blood from the veins and forces it into the ventricles
atrium
rate at which the heart pumps
heart rate
network of hollow tubes that circulates blood throughout the body
blood vessels
heart rate x stroke volume, the overall performance of the heart
cardiac output
fluid that circulates int he heart, arteries, capillaries and veins; carries nutrients and oxygen to all parts of the body and rids the body of waste products
blood
amount of blood pumped with each contraction
stroke volume
vessels that transport blood away from the heart
arteries
vessels that transport blood away from the capillaries from the heart
veins
very small veins that connect capillaries to the larger veins
venules
smallest blood vessels and the site of exchange of chemical and water between the blood and tissues
capillaries
small terminal branches of an artery, which end in capillaries
arterioles
a system of organs that collects oxygen from the external environment and transports it to the blood stream
respiratory system
composed of skeletal structures and soft tissues that work together to allow proper respiratory mechanics to occur and help pump blood back to the heart during inspiration
respiratory pump
process of actively contracting the inspiratory muscles to move air into the body
inspiration
process of actively or passively relaxing the inspiratory muscles to move air out of the body
expiration
process of getting oxygen from the environment to tissues of the body
diffusion
highest rate of oxygen transport and utilization achieved at maximal physical exertion
maximal oxygen consumption
Inspiration or Expiration?
Internal Intercostals
Expiration
Inspiration of Expiration?
Diaphragm
Inspiration
Inspiration or Expiration?
External Intercostals
Inspiration
Inspiration or Expiration?
Scalenes
Inspiration
Inspiration or Expiration?
Abdominals
expiration
Inspiration or expiration?
Pec Minor
Inspiration
Inspiration or expiration?
sternocleidomastoid
inspiration
gathers deoxygenated blood returning to the heart from the entire body
right atria
gathers oxygenated blood coming to the heart from the lungs
left atria
receives de-oxygenated blood from the right atrium and then pumps it to the lungs
right ventricle
receives oxygenated blood from the left atrium and pumps it to the entire body
left ventricle
What’s the best location to take a pulse?
radial; gentle touch, best to measure upon waking or after 5 minutes complete rest
How should you count heart rate during exercise?
count beats in 6 seconds and add a zero to it
The rate at which the heart pumps
heart rate
amount of blood pumped out with each contraction
stroke volume
stroke volume x HR =
cardiac output (overall performance)
Conducting airways of the respiratory passages
nasal cavity oral cavity pharynx larynx trachea right and left pulmonary bronchi bronchioles
respiratory airways
alveoli and alveolar sacs
