Study Notes

Frog Body Parts and Their Functions

External nares or nostrils: Facilitate air entry and exit for respiration.
Esophagus: A tube connecting the mouth to the stomach, allowing food passage.
Tympanic membrane: Known as the eardrum, it detects sound waves.
Glottis: The opening from the mouth into the respiratory pathway.
Tongue: A muscular organ at the mouth's front, extends to catch prey like insects.
Maxillary teeth: Sharp teeth located in the upper jaw, help to grip captured prey.
Vomerine teeth: Small projections on the upper mouth aiding in prey retention.
Eustachian tube openings: Connect the mouth to the middle ear, balancing air pressure.
Nictitating membrane: A transparent eyelid layer that cleans and protects the eye.
Cloacal opening: Exit point for undigested food, urine, eggs, and sperm.
Stomach: Stores food and initiates digestion by mixing it with enzymes.
Small intestine: Main site for digestion and nutrient absorption.
Duodenum: The initial segment of the small intestine, receiving food from the stomach.
Pancreas: Excretes digestive enzymes into the duodenum for food processing.
Gall bladder: Stores bile produced by the liver for digestion.
Large intestine: Stores undigested food before it is expelled.
Liver: Produces bile and manages processed food molecules.
Urinary bladder: Stores urine until it is excreted from the body.
Fat bodies: Fat deposits crucial for hibernation and reproductive activities.
Spleen: Part of the circulatory system, responsible for the creation and disposal of blood cells.
Cloaca: Common exit for digestive and urogenital waste.
Heart: The central organ of circulation, consisting of three chambers.
Anterior vena cava: Major vein transporting blood from the head and upper body to the heart.
Posterior vena cava: Major vein carrying blood from the lower body towards the heart.
Sinus venosus: A pouch receiving blood from the vena cava before it enters the heart.
Right atrium: Heart chamber collecting oxygen-depleted blood from the lungs.
Pulmonary veins: Vessels that convey oxygen-rich blood from the lungs to the left atrium.
Ventricle: Heart chamber that pumps blood to the lungs and throughout the body.
Truncus arteriosus: Major artery transporting blood from the ventricle to distribute it across the body.
