CH6 Cardiorespitory Flashcards
Atrium
Superior chamber of heart gathers blood, returning to heart
Ventricle
Inferior chamber of the heart
pumps blood to the lungs and body
…write it out
Blood flow through the ❤️
Resting Heart rate
60–100
Sino atrial node
Located in right atrium
Initiates electrical signal, causing heart to beat
Atrioventricular node
Located between the atria and ventricles
Delays impulse from SA node before allowing to pass to ventricles 
Stroke, volume
Amount of blood pumped out of heart with each contraction
End, diastolic volume
Filled volume of ventricle before contraction
End systolic volume
Volume of blood remaining in ventricle after ejection
Bradycardia
Heart rate less than 60 BPR
Tachycardia
Heart rate greater than 100 BPR
Cardiac output
Overall performance of the ♥️
(heart rate X stroke volume)
Arteries
Vessels that transport blood Away from the heart
Capillaries
Smallest blood vessels
Site of exchange of elements between blood and tissues
Veins
Vessels that transport blood back to the heart
Arterioles
Small arteries that eventually divide into capillaries
Venules
Small veins that allow blood to drain from capillaries into larger veins
Vanous pooling
Accumulation of blood into the extremities due to slow blood flow through the veins or backflow

Stages of hypertension
Bones, inspiration, muscles, expiration muscles
Structures of respiratory pump
Valsalva maneuver
A process that involves expiring against a closed windpipe, creating additional intra-abdominal pressure and spinal stability
Conducting airways, respiratory airways
Structures of respiratory passages
Tachypnea
Respiratory rate that is too fast
Greater than 24 breaths per minute
Bradypnea
Respiratory rate that is too slow
Fewer than 8 breaths per minute
Dyspnea
Shortness of breath, labored breathing
