Dogfish 2 Flashcards
shiny epithelium lining heart cavity
Parietal pericardium
shiny epithelium covering heart
visceral pericardium
tissue separating pleuroperitoneal and pericardial cavities
transverse septum
chambers of heart
sinus venosus, atrium, ventricle, conus arteriosus
receives blood from heart, specifically conus arteriosus
ventral aorta
blood passes through these on its way to being oxygenated at gills (5 pairs)
afferent branchial arteries
carries blood away from gills, 4 pairs, pass dorseromedially into dorsal aorta
efferent branchial arteries
on roof of pharynx, supplies most of body with blood
dorsal aorta
first major paired branches of dorsal aorta
subclavian artery
arise from efferent branchial arteries, pass anteriorly and then join hyoidean artery
paired dorsal aortae
branching off paired dorsal aorta just anterior to first efferent branchial artery
hyoidean artery
internal carotid extends anteriorly and branches into this artery at level of spiracle, artery extends into chondrocranium
stapedial artery
union of hyoidean and paired dorsal arteries forms
internal carotid artery
first branch of dorsal aorta, continues posteriorly along right side of stomach
celiac artery
anterior one of two arteries that arise close together at the level of the spleen
anterior mesenteric artery
extension of anterior mesenteric artery onto intestine
posterior mesenteric artery
final paired branches of dorsal aorta, at level of cloaca, pass posterolaterally dorsal to kidneys toward pelvic fins
iliac artery
branches of iliac artery that separate before extending into pelvic fins
femoral artery
large vein that lies along the anterior part of the bile duct, confluence of 3 main vessels
hepatic portal vein
drains each side of the head and branchial region
anterior cardinal sinus
each posterolateral corner of the sinus venosus leads through this short but large vessel which receives blood from many main vessels and takes blood back to heart
common cardinal vein
lies dorsolateral to esophagus, large space bounded by a thin walled membrane, curves toward dorsal midline
posterior cardinal sinus
narrowing of posterior cardinal sinus, lateral to dorsal aorta
posterior cardinal vein
extends anteriorly along ventrolateral body wall
lateral abdominal vein
passes anteriorly through hemal arches of vertebrae
caudal vein
bifurcation of caudal vein
renal portal vein
lateral outer portion of the eye modified so that it is transparent
cornea
