Facts
• Instead of drinking water, frogs soak it into their
body through their skin.
• Frogs breathe through their nostrils while also
absorbing about half the air they need through their
skin.
• Frogs use their sticky, muscular tongue to catch and
swallow food. Unlike humans, their tongue is not
attached to the back of its mouth. Instead it is
attached to the front, enabling the frog to stick its
tongue out much further.
• The common pond frog is ready to breed when it is
only three years old.
Stomach - Stores
food and mixes it with enzymes to begin digestion.
Internal

digested food.
Duodenum - The anterior (front) part of the small intestine into which
food passes from the stomach
Pancreas - Gland which secretes digestive enzymes into the duodenum.
Gall Bladder - Sac which stores bile
Large Intestine - Posterior organ of the digestive system which stores
undigested food.
Liver - Secretes bile and processes digested food molecules
Urinary Bladder - The organ that collects and stores urine until released.
Fat Bodies - Masses of fat in the body cavities of frogs. Needed for
hibernating and mating
Spleen - Organ in the frog’s circulatory system that makes, stores, and
destroys blood cells.
Cloaca - Organ through which the products of the frogs digestive and
urogenital system pass when discharged from the body.
External anatomy
• External nares or nostrils - Anterior
openings for the entry or exit of air.
• Esophagus - Tube that connects the mouth and
the stomach in a frog.
• Tympanic Membrane - The eardrum receives sound waves
• Glottis - The opening from the mouth into the
respiratory system
