Fetal heart

3 fetal shunts

DA, ductus venosus, foramen ovale

ductus venosus becomes what

ligment venosum

Most sensitive period for cardiac development is between

3.5 to 6.5 weeks

what is the first organ system to reach functional state

cardiovascular

circulation begins at the end of the blank week

3

heart begins to beat at blank week

5

Right and Left Atria are separated by a partition called the

interartrial septum

Right and left ventricles separated by

intraventricular septum

The interventricular septum forms a blank degree

45

rt side valve

tricuspid

valve between LA and LV

mitral

valves of the AO and PA

semilunar

what ventricle may be larger

rt

where is the moderator band seen

RV

most common congeital heart defect

ventricular septal defect

The point where the lower part of the atrial

septum meets the upper part of the ventricular

septum and where the atrioventricular valves

insert is called

cardiac crux

where do the pulmonary veins are seen entering

left atrium

what valve should insert more apically

tricuspid

when the beam insonates the apex of the heart first

apical

the beam insonates the base of the heart first

basal

3 vessel view is what from bottom to top

pa, ao, sic

what is seen closest to the chest

right ventricle

what is seen closes to the spine

left atrium
