Primitive Blood Vess

Blood Vessel Development in embryo

arch 1, 2, 5 regress - but some cells from 1 and 2 form maxillary and stapedial arteries
arch 3 forms the Common Carotid A. and proximal portion of internal carotid (distal made by cranial dorsal aorta). External carotid derived from remnants of crainal aortic sac
Left arch 4 adult aortic arch (also recieves contributions from aortic sac, and left dorsal aorta)
Left 7th Intersegmental Left Subclavian
Right arch 4 proximal portion of right subclavian (along with the intervening dorsal aorta)
Right 7th Intersegmental distal portion of the right subclavian
Right arch 3 and 4 brachiocephalic trunk
arch 6 connects pulmonary artery to lungs. Left proximal portion of arch forms Ductus Arteriosus (the right prox. portion is lost which is why R recurrent is under R subclavian, while L recurrent is under ligamentum arteriosum)
Primitive Dorsal Aorta 2 aortae fuse to form one that becomes the dorasl and thoracic aortae in the adult
Dorsal Intersegmental Arteries 6 cervical intersegmentals are lost, but their vertical anastomoses becomes the Vertbral Artiers. Thoracic Intersegmentals and their vertical anastomoses becomes the Intercostal AA, Internal Thoracic AA, and Sup./Inf. Epigastric AA
Vitelline Arteries (supplied the yolk sac) Connect up with Dorsal Aorta and form the Celiac Trunk, Sup. Mesenteric, and Inf. Mesenteric AA
Umbilical Arteries originally a branch off the aorta and later connect up with the 5th lumbar Intersegmentals(futural Iliac artery). Distal ends regress to form the medial umbilical ligaments. Proximal ends form the Sup. Vesicular AA supplying the bladder
Vitelline Veins form hepatic sinusoids in the liver. Prox. right vein forms R hepatocardiac channel that eventually becomes the bottom part of Inf. Vena Cava. Distal segments of both R/L veins contribute to Portal, Sup/Inf Mesenteric, and Splenic Veins
Umbilical Veins Connect up with hepatic sinusoids. All regress except distal left vien forms the ductus venosus to bypass placental blood away from the liver. After birth, this regresses into the ligamentum tere hepatis and ligamentum venosum
Anterior Cardinal Vein [R Ant + R Common = Sup Vena Cava],[anastomoses between R/L ant = brachiocephalic], [R common = subclavian], [L ant regress into L sinus horn = coronary sinus]
Subcardinal Vein (joined by post. cardinal V) veins of kidney and gonads and contribute to abdominal inf. vena cava
Suprcardinal Vein (joinded by post. cardinal V) forms portions of IVC and azygous system - basically drains body wall
Foregut pharynx to 1st part of Duodenum (up to ampulla of vater/liver bud)... anything in abdomen supplied by celiac trunk
Midgut 2nd part of duodenum to 2/3 of transverse colon .... anything in abdomen supplied by sup. mesenteric
Hindgut Last 1/3 of transverse colon to rectum ... anything in abdomen supplied by inf. mesenteric and Sup/Midle Rectal arteries
Ventral Mesentary (forms where liver pulls away from septum transversum) becomes Lesser omentum (post to liver) and falciform lig (ant to liver)
Dorsal Mesentary (intially continuous entire lenght of embryo behind the gut tube) forms mesentary of peritoneal structures as well as greater omentum. Areas that resorb the mesentary become secondarily retroperitoneal (duodenum, acending and decending colon, pacnreas)
Ventral and Dorsal buds foregut and midgut mesoderm that form the pancreas. ventral bud migrates to meet dorsal budd - ventral bud forms uncinate process
Hepatic diverticulum duodenal endoderm that grows into ventral mesentary and lower part of septum transversum to form hepatocytes and hepatic duct of liver (stroma of liver comes from splanchnic meso)
Cystic diverticulum bud that forms just caudal to hepatic diverticulum to become the gallbladder
Cloaca separates inot post rectum and ant. primitive urogenital sinus due to the growth of the urogenital septum between the 2. Ectoderm on outside of cloaca = anal membrane that ruptures at week 9 to form the anus
Diaphragm (what 5 components contribute to it?) 2 pleuroperitoneal membranes, mesentary of esophagus, septum transversum, rim of mm pulled from body wall
