How many chambers, valves, and veins are in the heart
4 of each
how many great veins are there in the heart
2
what are the two great veins
IVC and SVC
what are the 4 smaller veins
pulmonary veins
what are the valves of the heart
mitral and tricuspid
the pulmonary veins bring oxygen from lungs to
the heart
the heart arises as two cords called
cardiogenic cords
When the cords canalize what do they form
two heart tubes
what do the two heart tubes do
fuse to form a single tube
what week does the partitioning of the atrioventricular canal begin
week 4
what eventually forms the chambers of the heart
endocardial cushions
what week do the endocardial cushions fuse
week 5
what gives us left and right sides of the heart
the endocardial cushions fusing together
what is a common defect in trisomy 21
Defect of the endocardial cushions fusing together
what two septa’s are involved with the partitioning of the common atrium
septum primum and septum secundum
partitioning of the primitive ventricle begins with what
muscular ridge of the single ventricle near apex
what polypeptide is responsible for vasodilation of pulmonary arterioles
bradykinin
bradykinin causes what
the lungs to fill with air
when does gas exchange begin
when fetus is fully disconnected
the left coronary artery comes from where
the left sinus
what do the coronary arteries do
perfuse the heart muscle and inner structures
what does the left main coronary artery divide into
the left circumflex and left anterior descending coronary arteries
the left circumflex coronary artery supplies what
the left ventricle
The right coronary artery courses in what groove
the atrioventricular groove
what does the right coronary artery separate
the atria form ventricles
what do the cardiac veins do
drain heart
most of the veins drain into what
coronary sinus and empty into right atrium
veins that do not drain into the coronary sinus drain where
directly into the right atrium
what is the primary pace maker
SA node
SA node is reflected by what wave
P wave
the AV node does what
holds onto the pulse
what position is the patient position for an echo
left lateral decubitus
