describe the development of primary and seconary heart field and what do they give rise to??
The primary heart field is induced by signals from the_______
what does it form?
what will be the pericardium cavity
what forms the shape of the heart (bending) ?
describe the early heart and how it start pumping blood?
As the heart tube grow and bulge into the pericardial cavity, it is connected to the _____________ and this structure gives rise to __________which will then form what 3 things?
vasculogenesis vs angiogenesis
hereditary hemorrhagic telangiectasia
bevacizumab, when are patients treated with this?
What is pre-eclampsia? How is vascular endothelial growth factor (VEGF) and Placental Growth factor (PIGF) and fas-like tyrosine kinase-1 (sFlt-1) affected?
where does Hematopoiesis occur? during development
how are the RBC at the beginning?
arteries from the neck and head are derived from the______
In the rest of the body. Arterial patterns primarily develop from the ____________. which arteries emerge from there?
From the dorsal aorta, various arteries
emerge:
1. Posterolateral arteries supply __________________________
- Lateral arteries: supply the____________________
- Ventral arteries (vitelline and umbilical):
Vitelline arteries give rise to the_________
umbilical arteries at first drain the ________
They eventually regress to form the_______________________
when does the pharangeal arches form?
where do pharangeal arches arise from?
what happens during coarctattion of aorta?
patients with __ should be screened for thi s
preductal Coarctation of aorta vs post- ductal?
which arteries could be damaged in post ductal?
patent ( persistent) ductus arterious.
what kind of infection can lead to this?
may cause _______hypertension
vetilline vein give off 5 more braches related to GI. what are they?
A. Vitelline veins are paired in the embryo (right and left). They contribute to:
- Hepatic portion of inferior vena cava (IVC):
- Hepatic veins and sinusoids:
- Ductus venosus:
- Portal vein:
- Inferior mesenteric vein, superior mesenteric vein, and splenic vein:
vitelline and umbilical veins
cardinal veins
C. Cardinal Veins: The cardinal veins give rise to many important veins in the adult circulatory system:
______________give rise to:
- _______________, which carries deoxygenated blood from the upper body back to the heart.
- _______________ responsible for draining blood from the brain and face.
abnormalities
* Left superior vena cava occurs
* Double superior vena cava
Cardinal Veins: The cardinal veins give rise to many important veins in the adult circulatory system:
- _________________:
- Contribute to the formation of the posterior cardinal portion of _________and______________, which
return blood from the lower limbs and pelvic organs to the heart.
Cardinal Veins: The cardinal veins give rise to many important veins in the adult circulatory system:
__________________:
* Form parts of the__________, _________, and ________________, which drain blood from the
kidneys, gonads (testes/ovaries), and other structures.
4._____________:
* Form portions of the ________,____________, ___________(Lt.),
and ____________ (Rt.), all of which contribute to draining blood from
the thoracic region and the body’s wall back to the heart.
- Double inferior vena cava occurs when the left supracardinal vein
persists forming an additional inferior vena cava below the level of the
kidney

what what braches does it give off?
variations in right and left coronary arteries ?
