the greeter the venous return,
the greater the strength of the
contraction
atrio-ventricular node
tissue found in the trio ventricular
septum that from part of the heart
conductive systems
perkinje fibers
specilised nerev fibres found in the ventricls
Stroke volume
volume of blood leaving the left ventricle per beat
intrinsic
tha name given to the idea that the heart
generates its own contraction from with in the
heart ( the heart is self paced )
sino-atrial node
small mad of cardiac tissue located in the wall
of the right atrium which generates the heart
beat
systemic circulation
blood circulation from the
heart to the body and then
back to the heart
Cardiovascular drift
an increases in the heart rate that occurs
during prolonged exercise that compensates
for the decreased in the stroke volume in an
attempt to maintain cardiac output
Bradycardia
the reduction in the testing
heart rate that accompanies
traning
Hypertrophy (athletes heart)
the increased size of the heart,
focused on the increased size of the
left ventricle
Chemoreceptors
group of cells that detect
changes in the blood acidity
Cardiac output
volume of blood leaving
the left ventricle per
minute (stroke volume X
heart rate)
Ejection fraction
proportion of blood in left
ventricle pumped out each beat
bundle of his
specialised bindles of nerve tissues found in
the interventricular septum that form part
of the hearts conductive system
pulmonary circulation
blood circulation from the
heart to the lungs and the
returns to the heart
