Getting To Know Your Frog Anatomy
Directions• Use this presentation to
complete the 1st table in Section 1 of your Frog Dissection Booklet.
• READ THE DIRECTIONS for each section throughout the entire book!
Skin Integumentary System
• The frogs skin is permeable. (allows water in and out of body)
• Has glands that release toxins for protection against predators.
• Camouflage color and pattern to hide from predators.
• Used to regulate body temperature.
Heart Circulatory System
• 3 chambers - 2 atrium on top 1 ventricle on bottom.• Circulates blood throughout
the body.
Right & Left LungsRespiratory system
• Frogs use lungs for CO2 and O2 exchange.
• Lungs used for buoyancy while swimming.
Liver - Digestive System• The largest organ
inside of the body.• Composed of three
lobes. • Secretes a
digestive juice called BILE, which is needed to digest fats in the diet.
Gall bladderDigestive System
• A small balloon like organ located under the liver.
• Stores bile
Stomach – Digestive System• In the frog -
First site of chemical digestion.
• Breaks down food mechanically and chemically
Small IntestineDigestive System
• Narrow tube near the end of the digestive tract.
• Digests food into nutrients which are absorbed into the bloodstream through villi.
Large IntestineDigestive System
• Short tube that stores solid waste for excretion.• Absorbs water.
Spleen – Circulatory System• Stores and recycles blood
cells.
Fatty Bodies - Digestive & Reproductive Systems
• Stores fat which gives the frog energy for hibernation and mating.
• Helps frog stay warm.
• Enables frog to float.
MesentaryIntegumentary System
• A thin transparent tissue that hold the intestines together.
• Surrounding organs and blood vessels are also held in place.
BladderUrinary System
• Stores liquid waste – urine.
EsophagusDigestive System
• Short tube that connects the frogs mouth to its stomach.
