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
path of blood in heart of shark
sinus venous, artium, ventricle, conus arteries, then ventral aorta, afferent arteries to gill then efferent arteries
path of blood in gills
the afferent to pretremeric, postremeric the efferent arteries
how does the structure of the gills help the function
the loop helps the blood go one way so deoxygenated doesn’t mix with oxygenated
what is the systemic veins system?
return blood direct form capillary to heart
what does portal vein system?
blood travels to various capillary beds before it reaches heart
dorsal aorta
the efferent arteries lead to this and this is gonna send blood to the posterior organs of body
celiac artery
branches off the dorsal aorta and leads to the gastric hepatic artery
gastrohepatic artery
branches off the celiac and separates into gastric artery going to stomach and hepatic artery going to liver
gastric artery
comes off the gastrohepatic artery and goes to stomach
pancreaticomesentric artery
branches off the celiac and goes to pancreas and intestine
anterior intestinal artery
branches off the pancreaticomesentric artery to the anterior of intestine
annular arteries
comes off the anterior intestinal artery and runs along the side of the intestine
anterior mesenteric artery
comes off posterior of the dorsal artery
posterior intestinal arteries
comes off anterior menstric artery to the posterior of intestine
lienogastric (gastrospleenic) artery
comes off the very bottom of dorsal artery to the spleen and the bottom of stomach
cadual artery
the very bottom of dorsal artery goes into the tail
brachial arteries and veins
comes from and to the subclavian goes into fins
renal artery
goes the kidneys from the dorsal aorta
iliac arteries
branches of the dorsal to the pelvic fins
caudal vein
a part of the renal portal system, goes to kidney’s renal portal vein
renal portal vein
branches off the caudal vein
afferent renal vein
comes off the renal portal vein to kidneys
hepatic portal vein
goes to hepatic sinus in the liver
top of the pancreas and is the combination of the gastric, pancreaticomesentric and lienomesenteric veins
gastric vein
goes to hepatic portal vein
pancreaticomesentric vein
goes to hepatic portal vein
anterior intestinal vein
goes into pancreaticomestrentric vein
lienomesentric vein
goes to hepatic portal vein
posterior intestinal vein
goes to lienomesentaric vein
posterior lienogastric vein
goes to lienomesentaric vein
posterior cardinal sinuses and vein
takes blood form kidneys, brought by the afferent renal vein, back to heart
efferent renal veins
goes to posterior cardinal sinus
lateral abdominal veins
from the side to the heart
hepatic vein
in the sinus venous
What makes up the Hepatic Portal System
- annular vein
- anterior and posterior intestinal vein
- posterior lienogastric vein
- lienomesentric vein
- pancreaticomesenteric vein
- gastric vein
- hepatic portal vein to liver
What makes up the Renal Portal veins
-caudal vein
- renal portal vein
- afferent and efferent renal veins
