Frog Body Parts and Functions

Anatomy of a Frog’s Head

Functions of the body parts that make up the frog’s head 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

Functions of the body parts that make up the frog’s head Tongue - Muscular structure attached to the front of the mouth which is extended to catch insects (its food). Video Here Maxillary Teeth - Sharp teeth in the maxilla of a frogs mouth that function to hold captured prey. Vomerine Teeth - Small projections in the top of a frog’s mouth that function in holding captured prey. Eustachian tube openings - Openings in the mouth that lead to tubes that connect to the middle ear to equalize air pressure

External Anatomy of the Frog

Functions of the External Anatomy of the Frog Nictitating Membrane - A transparent part of a frog’s lower eyelid that moves over the eye to clean it and protect it. Cloacal Opening - Opening of cloaca through which undigested food, urine, eggs, and sperm are passed. http://youtu.be/q50Yphp1gzI

Internal Anatomy of a Frog

Functions of the Internal Anatomy of a Frog: Stomach - Stores food and mixes it with enzymes to begin digestion. Small Intestine - The principal organ of digestion and absorption of 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.

Functions of the Internal Anatomy of a Frog: 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.

Frog Reproductive System

Frog Reproductive System Functions Urinary Ducts - Tubes in a frog that carry urine from the kidneys to the cloaca Urinary Bladder - The organ that collects and stores urine until released. Adrenal Glands - Organs located near the kidneys which secrete hormones. Ova or Eggs - Female sex cell or gametes

Frog Reproductive System Functions Ovaries - Organs of the female reproductive system that produce the eggs. Oviducts - Tubes of a female frog’s reproductive system that carry eggs from the ovaries to the cloaca. Testes - Male sex organs that produce sex cells (sperm). Sperm - Male sex cell or gametes. Seminal Vesicles - Enlarged distal sections of the male frog’s urinary ducts that collect sperm prior to entry into the cloaca.
