Frog Dissection

This post will take you through how to dissect a frog! But first, let's look at some facts about frogs:

Where are they found?
Frogs are found in wet areas, near freshwater. They like damp, wet areas. They do not live in water but need it to survive. They spend adolescence in the water, then live on land for the duration of their lives.



What do they eat?
Frogs eat various types of small insects


How do they breathe?
Frogs breathe mainly through their lungs which they develop in adulthood, during hibernation however, they breathe through their skin through a gas exchange process.


Fun fact!
Frogs do not drink water, they absorb it through their skin to stay hydrated.

Tongue- The tongue of the frog is a muscular structure used to catch insects for food

Jaw- The jaw is where the tongue is attached

Lungs- The lungs of the frog supply oxygen to the frog

Heart- The heart of a frog has 3 chambers. The right and left atriums receive blood into the heart and a singular ventricle pumps blood out

Fat bodies- These are necessary for hibernating due to the frog's inability to regulate its own body temperature. The fat bodies provide some insulation and warmth to three frog during cold months.

Spleen- The spleen is part of the frog's circulatory system which makes, stores and destroys blood cells. It is where blood is held

Large intestine- This is the posterior organ of the digestive system, it stores undigested foods

Small intestine- This is the principal digestive organ which absorbs digested food

Pancreas- The pancreas secretes digestive enzymes into the front part of the small intestine called the duodenum which food passes into from the stomach

Liver- The liver processes digested food and secretes bile

Stomach- The stomach stores food and mixes it with enzymes to kick start digestion
