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
