Frog Dissection Flashcards
How many chambers does the Frog heart have
Three
Explain how a frog heart is less effective because of how many chambers it has
Frog only has a single ventricle therefore oxygenated and deoxygenated blood mix. The blood that is pumped around the body is therefore not fully oxygenated. And humans we have two separate ventricles so only oxygenated blood is pumped around the body.
What is the membrane that holds the coils of the small intestine together
Mesentry
This organ is found under the liver and it’s used to store bile
Gallbladder
This organ is the first major site of chemical digestion
Stomach
Eggs, sperm, urine and waste all empty into this structure, nicknamed the sewer
Cloaca
The small intestine leads to this organ
Large intestine
Blood leaves the heart through what large vessel
Conus arteriosis
Yellowish structures that serve as an energy Reserve
Fat bodies
The first part straight part of the small intestine
Duodenum
This pair of organs filters wastes from the blood
Kidneys
A spider web like membrane that covers the organs
Peritoneum
Regulates the exit of partially digested food from the stomach
Pyloric Sprinter
Frogs do not have this organ that we need for breathing. What organ do they use instead
They do not have a diaphragm. Instead they use their mouth.
What is the largest organ in the body cavity
The liver
Holding area for blood, also has a function in the immune system
Spleen
Where does the esophagus lead
The stomach
Bio moves from the gallbladder to the duodenum through what duct
The bile duct
What organ, located near the stomach, makes insulin
The pancreas
What structure is found above the kidneys in male frogs only
The testes
What are the tympani commonly called?
The eardrums
What are the teeth in the middle of the roof of the mouth called
Vomerine teeth
A transparent, third lid fond over the eyes
Nictitating membrane
Connect the pharynx to the ear
Eustachian tubes
Frogs have less efficient Hearts than humans, however their oxygen absorption is supplemented because aside from their lungs, they can also breathe using what organ
The skin
Compare the differences between human and frogs and how waste is excreted
Frogs have a cloaca where urine, sperm, eggs, and feces all exit. Humans have a separate opening for solid waste and liquid waste
