Shark Lab 2&3: Circulatory & Respiratory system Flashcards
pericardium
the sac that holds the heart and important blood vessels
sinus venous
assessory chamber, collects the blood from the body to be pushed into the atrium
atrium
1st chamber blood goes into, black and thin wrapped around the ventricle
ventricle
2nd chamber, spongy and thick what pushes blood out of heart to the gills
conus arterious
chamber that holds blood for for the ventral aorta
coronary arteries
deliver oxygenated blood form gills to heart
semilunar valves
can’t be seen but inside the heart to shut blood off when one chamber is contracted
ventral aorta
comes from the conus arterious and the 5 afferent arteries branch off it
afferent branchial arteries
5 of them and leads to each of the gills, number 1 to 5 from the anterior of heart to the posterior
holobranch
4 of the arches after the hyoid have lamellae on both sides of their septa
hemibranch
only has lamellae on the posterior side of septa (hyoid arch)
gill rakers (what what shark does it show up in)
shows up on the dogfish
gill filaments (aka..
primary lamellae
interbranchial septa
4 the structure in between the gill slits
gill rays
supports the interbranchial muscle
efferent branchial arteries
oxygenated blood leaving the gills to the Doral aorta
gill rakers
keeps food out
trematic loop
the loop of artery in the gill, pretrematic on the anterior side and the postrematic lies on the posterior side
paired Doral aortae
off the hyodian, takes blood to the Dorsal aorta
internal carotid artery
hyoidean turns into one and oxygenated blood goes to the brain
hyoidean artery
around the spiracle branches off the 1st efferent
stapeadial
junction of the hyoidean and the internal but its deep down most likely not seen
subclavian arteries
artery that supplies pectoral fin with oxygen
