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
