Frog Dissection

Frog Dissection 

-Frogs are found in every continent all over the world except for Antarctica. They live in warmer climates since they are cold-blooded creatures, creatures that take in their heat from their environment.

-They get their nutrition mainly from insects and small animals such as minnows, earthworms,  and spiders.

 -When submerged in water, a frog’s respiration takes place through their permeable skin. Outside of water they take in air through their nostrils, which passes through their lungs. Although they don’t have diaphragms or ribs, they still breathe similarly to humans.

-Like trees, frogs form rings that reveal their age when counted. Each year, their  bones form a new growth ring when they are in hibernation.

Dissection 

Major internal/external anatomy-

Liver-aids in digestion, makes bile

Heart-pumps blood throughout the frog’s body

Major internal/external anatomy-

Gall Bladder- sac that stores bile

Lungs-exchanges oxygen and co2 from the body

Stomach-breaks down food; it’s the first site of chemical digestion

Major internal/external anatomy-

Intestines-the small intestine absorbs nutrients from food and the large intestine collects waste and absorbs water

Fat bodies-masses of fat in the body cavities of both sex

Major internal/external anatomy-

Kidneys-filter blood

 

Oviduct-eggs travel through to the cloaca
