gill rakers (what what shark does it show up in)

Answer 12

shows up on the dogfish

Question 13

gill filaments (aka..

Answer 13

primary lamellae

interbranchial septa

Answer 14

4 the structure in between the gill slits

Question 15

gill rays

Answer 15

supports the interbranchial muscle

Question 16

efferent branchial arteries

Answer 16

oxygenated blood leaving the gills to the Doral aorta

Question 17

gill rakers

Answer 17

keeps food out

Question 18

trematic loop

Answer 18

the loop of artery in the gill, pretrematic on the anterior side and the postrematic lies on the posterior side

Question 19

paired Doral aortae

Answer 19

off the hyodian, takes blood to the Dorsal aorta

Question 20

internal carotid artery

Answer 20

hyoidean turns into one and oxygenated blood goes to the brain

Question 21

hyoidean artery

Answer 21

around the spiracle branches off the 1st efferent

Question 22

stapeadial

Answer 22

junction of the hyoidean and the internal but its deep down most likely not seen

Question 23

subclavian arteries

Answer 23

artery that supplies pectoral fin with oxygen

Question 24

path of blood in heart of shark

Answer 24

sinus venous, artium, ventricle, conus arteries, then ventral aorta, afferent arteries to gill then efferent arteries

Question 25

path of blood in gills

Answer 25

the afferent to pretremeric, postremeric the efferent arteries

Question 26

how does the structure of the gills help the function

Answer 26

the loop helps the blood go one way so deoxygenated doesn't mix with oxygenated

Question 27

what is the systemic veins system?

Answer 27

return blood direct form capillary to heart

Question 28

what does portal vein system?

Answer 28

blood travels to various capillary beds before it reaches heart

Question 29

dorsal aorta

Answer 29

the efferent arteries lead to this and this is gonna send blood to the posterior organs of body

Question 30

celiac artery

Answer 30

branches off the dorsal aorta and leads to the gastric hepatic artery

Question 31

gastrohepatic artery

Answer 31

branches off the celiac and separates into gastric artery going to stomach and hepatic artery going to liver

Question 32

gastric artery

Answer 32

comes off the gastrohepatic artery and goes to stomach

Question 33

pancreaticomesentric artery

Answer 33

branches off the celiac and goes to pancreas and intestine

Question 34

anterior intestinal artery

Answer 34

branches off the pancreaticomesentric artery to the anterior of intestine

Question 35

annular arteries

Answer 35

comes off the anterior intestinal artery and runs along the side of the intestine

Question 36

anterior mesenteric artery

Answer 36

comes off posterior of the dorsal artery

Question 37

posterior intestinal arteries

Answer 37

comes off anterior menstric artery to the posterior of intestine

Question 38

lienogastric (gastrospleenic) artery

Answer 38

comes off the very bottom of dorsal artery to the spleen and the bottom of stomach

Question 39

cadual artery

Answer 39

the very bottom of dorsal artery goes into the tail
