What structure becomes the portal vein?

right vitelline vein
Main venous drainage of the embryo

cardinal veins
Anterior and posterior cardinal drainage
- ant is the head
- pos is the body
- the common cardinal enters into the sinus venosus
What structure becomes the left brachiocephalic vein
- the shunt that develops between the right and left anterior cardinal veins
- the anterior cardinal develop into the right and left jugular veins and the SVC
Only adult derivative of the posterior cardinal veins

root of the azogus and the common iliac
gonadal veins are from

subcardinal
coronary sinus develops from

left horn of sinus vinosous
left common cardinal becomes

oblique vien of left atrium
azogus and hem azogus are from

supracardinal
adrenal veins are from

subcardinal
double SVC is from

persistent left anterior vittaline vein
abdominal aorta is formed from

fusion of the dorsal aortas
common iliac arteries are form

5th pair of lumbar arteries
three remnants of the posterior vitelline arteries

celic trunk, superior and inferior mesentaric
median umbilical ligaments

distal umbilical arteries
proximal umbilical arteries become

internal iliacs and superior vesical arteries
epicardial cells are derived from

sinos venosous
smooth part of right atrium

sinus veneroum
visual markers of meeting of primordial atrium and sinus venosoum

crista terminals and the sulcus terminals
three structures that meet to form the IV membranous septum

left and right bulbar ridges and the endocardial cushion
ventricular outflow
- right is the conus arterioles
- left is the aortic vestibule
What TGF factor is involved in looping of the heart

Nodal
situs inversus

transposition of the abdominal viscera
Ectopia aordis
- abnormal location of the heart
- can be on the outside of sternum
What two cardiac anomalies are usually seen together with incomplete absorption of the sinus venosoum
- sinus venomous (high) ASD
- partial anomalous venous return
What other cardiac defect is usually seen with cor trilocular biatrium

transposition of the great vessels
What is always present with truncus arterioles

vsd
What distinguishes aortopulmonary window from PTA

presence of semilunal valves with window
Two types of pulmonary stenosis
- infundibular stenosis
- pulmonary valve
1st pharingeal arch
- maxillary arteries
- some of external carotid
2nd pharyngeal arches

stapedial arteries to middle ear
3rd pharyngeal arches
- common carotids - proximal parts
- internal carotids- distal parts
4th pair pf pharyngeal arches
- left becomes arch of aorta
- right is proximal subclavien artery
5th pharyngeal arches

nothing
6th pharyngeal arches
- left is the left pulmonary artery and the ductus arterioles
- right right pumonaly artery
- the recurrent laryngeal nerves supply this set of arches, the right detail arch degenerates and explains why the right recurrent laryngeal nerve is located higher, it ascends up. The left is hooked around the ductus arterosus
Coarctation is associated with

turners syndrom
three main views on how coarctation occurs
- some muscle from the DA incorporates into the wall and constricts after birth
- just small
vascular ring of aorta around the trachea

abnormality of the 4th paryngeal arch
function of DV sphincter

contracts to shunt blood to the hepatic sinusoids to protect overload of the heart
inferior border of the septum secundum

crista dividens
What is released by the lungs and activated by oxygen to constrict the DA

bradykinin
left umbilical vein becomes?

round ligament of the live (ligamentum teres)
most common abnormality with maternal rubella infection

PDA
