Tympanum
Home
The tympanum, found just behind the
eyes, functions as the ears of the frog.
They receive sound waves both above
and below water allowing the frog to
hear.
External Nares
Home
The nares primary role is to let air into
and out of the frog. This is a view of
the nares from outside of the frog.
Internal Nares
Home
The nares primary role is to
let air into and out of the frog.
This is a view of the nares
from inside of the frog.
Maxillary Teeth
This set of
teeth is used
for holding
prey.
Home
This set of
teeth is also
used for
holding prey.
Home
Vomerine Teeth
The eustachian
tubes function to
equalize
pressure on both
sides of the
eardrum or
tympanum
Home
Eustachian Tubes
Tongue
The tongue aids
in swallowing and
catching prey. In
humans the
tongue also aids
in speech and
taste.
Home
Glottis
Home
The glottis is the opening between
the vocal chords at the upper part of
the windpipe or larynx.
Esophagus
Home
Food is swallowed
through the esophagus
where peristalsis aids
its movement to the
stomach.
Lungs
The lungs transport
oxygen to the blood
as well as remove
waste like carbon
dioxide through a
process called
respiration.
Home
Heart
Unlike the human heart the
heart of a frog only has
three chambers (two atria
and one ventricle) however
the role and function is the
same. The heart pumps
blood throughout the body
carrying oxygen and
nutrients and picking up
waste to be filtered by other
parts of the body.
Home
Large
Intestine
The main role of
the large intestine
is to absorb water
and store fecal
material until it
can be excreted
from the body.
Home
Small
Intestine
The small intestine
receives the mixture
of chyme from the
stomach through the
pyloric valve. In the
small intestine
nutrients are
absorbed from the
tiny villi lining the
inner walls of the
small intestine.
Home
Stomach
In the stomach food
is further broken
down by gastric
juices and
peristalsis until it
becomes a liquid
substance called
chyme.
Home
Liver
The liver produces
bile, a substance
that emulsifies
fats contained
within the food we
eat, and stores it
in the gall bladder
to be secreted into
the small
intestine.
Home
Gall Bladder
The gall bladder
stores bile that is
received from the
liver. Bile is
secreted from the
gall bladder into the
first section of the
small intestine
(duodenum) to help
aid in digestion.
Home
Spleen
The spleen helps to
destroy old red
blood cells and
lymphocytes, which
are cells that
produce antibodies
to help fight infected
and cancerous
cells.
Home
Kidneys
Home
The Kidneys filter out waste from the
blood through structures known as
nephrons. The waste removed is
combined with water to form urine.
Oviducts
& Eggs
The oviducts are
tubes that carry
eggs from the
ovaries to the
uterus. The eggs
are the female
reproductive cell.
Home
Testis
The testis are
the male
reproductive
gland that
produce sperm
and male
hormones such
as testosterone.
