Anatomy of the Heart, Conduction System of the Heart
Exercise 30 and 31
location of the heart in the thorax
superior heart chambers
inferior heart chambers
anterooms of the heart
equals cardiac muscle
provides nutrient blood to heart muscle
lining of the heart chambers
actual "pumps" of the heart
drains blood into the right atrium
right atrium and left atrium
right ventricle and left ventricle
Superior and Inferior vena cava
Left common carotid artery
Left subclavian artery
Right and Left pulmonary arteries
Right and left pulmonary veins
Right and left coronary arteries
Anterior cardiac vein
Anterior interventricular artery
Apex of the heart

mitrallbiscupid, left ventricle, aortic semilunar, aorta
6).......to the____________of the tissues, to the systematic veins to the ______________, ____________, and the ________________entering the right atrium of the heart.
capillary beds, inferior vena cava, superior vena cava, coronary sinus.
List the elements of the intrinsic conduction system in order starting from the SA node.
AV node----AV bundle----bundle branches----Purkinje fibers
Desribe what happens in the cardiac cycle immediately before the P wave
heart is in diastole
Desribe what happens in the cardiac cycle during the P wave
depolarization of the atria
Desribe what happens in the cardiac cycle immediately after the P wave (P-R segment)
contraction of thecycles
Desribe what happens in the cardiac cycle during the QRS wave
depolarization of ventricles
Desribe what happens in the cardiac cycle immediately after the QRS wave (S-T interval)
contraction of ventricles
Desribe what happens in the cardiac cycle during the T-wave
repolarization of ventricles
heart rate over 100 beats per minute
heart rate below 60 beats per minute
rapid, uncoordinated heart contractions that makes the heart useless as a pump.
