Unit 8: Shark Anatomy vs. Human Anatomy (external & Digestive) Flashcards
Towards the side; away from midline
lateral
Type of shark we are dissecting?
spiny dogfish shark
Exit hole for indigested waste for the human
anus
Opening where food enters the shark
mouth
The involuntary squeezing of the food through the GI tract is known as
peristalsis
What is absorbed in the large intestine of the human?
water
Separates the specimen into equal left and right sections
midsagittal plane
Back fin closest to the tail
Caudal dorsal fins
Openings that take in water and remove chemical scents from the water
Nostril nares
Opening where waste and pups exit the shark
cloaca
Exit hole for indigested waste for the shark
cloaca
tube that connects the pharynx with the stomach in both the shark and the human
esophagus
Bellyside lobe of the tail fin
Ventral Lobe of the Caudal Fin
Holes on the dorsal side of the shark
spiracles
Number of lobes for the shark liver
3
two long lateral lobes and one short medial lobe
Location where chemical digestion begin in the human
mouth
The equivalent of the sprial valves but in the human
villi
Towards the middle
medial
Caudal to the mouth
pharynx
Set of paired openings on the ventral side of the shark near the cranial end.
nostril nares
Two types of fins that stabilize the shark
pelvic and dorsal fins
Site of ingestion
mouth
Lobe of tail fin on the back side
Dorsal Lobe of the Caudal Fin
Where is bile used?
shark: spiral intestine
human: small intestine
Fins that steer and lift the shark in the water
pectoral fins
Caudal to the small intestines in the human
large intestine
location of the gallbladder
dorsal side of the medial lobe of the liver
Ventral most fins
pelvic fins
Tail fin
Caudal fin
Cranial to the spiral intestines
stomach
Back fin closest to the head
cranial dorsal fin
Openings that allow water to enter when the mouth is closed
spiracles
Location where chemical digestion begins in the shark
stomach
Where bile is stored in both the human and shark
gallbladder
Lateral most fins
Pectoral fins
Fin that propels the shark forward
caudal fin
Plane that separates the animal into cranial and caudal sections?
transverse
Site of egestion in the shark
Cloaca
Towards the tail or feet
caudal
Towards the head
cranial
Fins on the backside
dorsal fins
Towards the belly side
ventral
Gland that makes bile for both the human and the shark
liver
Found within the stomach these aid in the breakdown of the food into a liquidy substance
rugae
Chewing of the food is known as
mastication
Extensions off the pelvic fins that identify the shark as a male
claspers
What gland makes digestive enzymes for the spiral intestine?
pancrease
Caudal to the spiral intestine
rectum
Separates the specimen into ventral and dorsal sections
Another name for the throat
pharynx
Location where nutrients are absorbed in the shark
spiral intestine
Towards the backside
dorsal
Found within the spiral intestines these help absorb nutrients for the shark.
spiral valves
