Study Notes

Frog Body Parts

Nictitating Membrane: Transparent eyelid part that cleans and protects the frog's eye.
Cloacal Opening: Passageway where undigested food, urine, eggs, and sperm exit the body.
External Nares or Nostrils: Openings at the front of the frog's head for air intake and expulsion.
Esophagus: Tube connecting the mouth to the stomach for food transport.
Tympanic Membrane: Eardrum that receives sound waves, crucial for hearing.
Glottis: Opening leading from the mouth into the respiratory system, facilitating breathing.
Frog Tongue: Muscular structure used to capture insects, attached to the front of the mouth.
Maxillary Teeth: Sharp teeth located in the upper jaw, used for gripping prey.
Vomerine Teeth: Small projections on the roof of the mouth that assist in holding prey.
Eustachian Tube Openings: Openings in the mouth leading to tubes that help equalize air pressure in the middle ear.
Stomach: Begins digestion of food, producing hydrochloric acid to form chyme.
Small Intestine: Completes digestion and absorbs nutrients into the blood from chyme.
Gall Bladder: Sac that stores bile and contains enzymes necessary for fat breakdown.
Large Intestine: Receives waste from undigested food, reabsorbing water before elimination.
Liver: Cleans blood by removing toxins, produces bile, and processes digested food molecules.
Fat Bodies: Fat storage masses essential for hibernation, mating, and reproduction.
Spleen: Organ in the circulatory system that produces, stores, and recycles blood cells.
Heart: Pumps blood throughout the frog's body, delivering nutrients and oxygen while removing waste.
Kidneys: Filter blood to excrete excess water and maintain fluid balance.
Frog Lungs: Absorb oxygen into the blood, allowing carbon dioxide to be expelled during exhalation.
