Intake of food and air.
What are the internal nares in frogs?
Openings that allow air into the buccal cavity.
What is the function of the frog’s tongue?
To catch prey with its sticky surface.
What structure leads to the lungs from the buccal cavity?
The glottis.
What are the Eustachian tubes in frogs?
Tubes that equalize ear pressure.
What is the largest organ in the frog’s abdominal cavity?
The liver.
What is the function of the frog’s liver?
Produces bile for digestion.
Where is bile stored in frogs?
In the gallbladder.
What is the function of the frog’s stomach?
To break down food using digestive enzymes.
Where does nutrient absorption occur in frogs?
In the small intestine.
What is the function of the large intestine in frogs?
To absorb water and form waste.
What is the role of the pancreas in frogs?
It secretes digestive enzymes and hormones.
What does the spleen do in frogs?
It filters blood and recycles red blood cells.
What organ filters waste from the blood in frogs?
The kidneys.
Where is urine stored in frogs?
In the urinary bladder.
What reproductive organs do male frogs have?
Testes.
What is the function of the testes in frogs?
Produce sperm for reproduction.
Where is sperm transported in male frogs?
Through the sperm ducts to the cloaca.
What reproductive organs do female frogs have?
Ovaries.
What is the function of the ovaries in frogs?
Produce eggs for reproduction.
Where are the eggs transported in female frogs?
Through the oviducts to the cloaca.
What is the cloaca in frogs?
A common chamber for excretion and reproduction.
What is the function of the kidneys in frogs?
Filter waste and produce urine.
What is the function of the bladder in frogs?
Stores urine before excretion.
What are fat bodies in frogs?
Yellowish structures that store energy.
Why are fat bodies important during hibernation?
They provide energy when food is scarce.
What is the pericardial cavity in frogs?
The space that surrounds the heart.
What is the heart’s role in frogs?
Pumps blood throughout the body.
How many chambers does a frog’s heart have?
Three chambers: two atria and one ventricle.
What is the function of the lungs in frogs?
Exchange oxygen and carbon dioxide.
How do frogs breathe besides using lungs?
Through their skin (cutaneous respiration).
What are mesenteries in frogs?
Membranes that hold the intestines in place.
What is the function of the diaphragm in frogs?
Frogs lack a diaphragm; breathing occurs through buccal pumping.
What is the maxillary teeth function in frogs?
They hold prey but do not chew.
What are vomerine teeth?
Teeth on the roof of the mouth used for gripping prey.
What is the pharynx in frogs?
The cavity behind the mouth connecting to the esophagus.
What is the function of the esophagus in frogs?
Carries food from the mouth to the stomach.
What is the role of the peritoneum in frogs?
A membrane lining the abdominal cavity.
What are the mesenteries in frogs?
Membranes that hold intestines and other organs in place.
What is the rectum in frogs?
The last section of the digestive tract, storing waste before excretion.
What is the hepatic portal vein in frogs?
A vein that transports blood from the digestive organs to the liver.
What is the urinary duct in frogs?
A tube that transports urine from the kidneys to the bladder.
What is the oviduct’s role in frogs?
Carries eggs from the ovaries to the cloaca.
What is the fat body’s secondary function in frogs?
They provide buoyancy and thermal insulation.
What is the adrenal gland in frogs?
A gland located on the kidneys that produces hormones.
How does the circulatory system work in frogs?
The heart pumps oxygen-rich and oxygen-poor blood through the body.
What is pulmonary respiration in frogs?
Breathing using the lungs.
What is cutaneous respiration?
Breathing through the skin when submerged.
What is the pericardium in frogs?
A membrane surrounding and protecting the heart.
What is the role of the aortic arches in frogs?
Transporting blood from the heart to the body.
What is the function of the frog’s brain?
Controls body functions, movement, and sensory processing.
What is the optic lobe in frogs?
Processes visual information from the eyes.
What is the olfactory lobe in frogs?
Processes smell information.
What is the cerebellum’s role in frogs?
Controls muscle coordination and balance.
What is the medulla oblongata?
Controls involuntary functions like heartbeat and respiration.
What are the tympanic membranes in frogs?
Eardrum-like structures for detecting sound vibrations.
What is the frog’s nictitating membrane?
A transparent eyelid that protects the eyes underwater.
What is the function of the spinal cord in frogs?
Transmits nerve signals between the brain and the body.
What are cloacal apertures in frogs?
Openings used for excretion, reproduction, and waste elimination.
What is the function of the ventricle in the frog’s heart?
Pumps blood to the lungs and the rest of the body.
