A suitable isotonic solution would keep a heart beating outside of the body. Additionally, charges can be inserted into the solution to keep the Sino-atrial node in constant functioning.
Frog's internal body temperature is lower than that of a mammal lower temperature = slower heart rate
The heart is ALWAYS a part of the circulatory system.
A frog heart can never reach tetanus.
The heart is a muscle, but it is NOT in the muscular system, and pumps blood to all parts of the body :)
the cooler the frog the slower the heart rate, the warmer the faster
Yes they take out the heart when the frog is still alive.
On the inside.
In the freezing tundra, the frog cells allows it to freeze itself. The frogs heart stops beating, blood stops, and it cannot move. When the spring arrives, the frog body thaws and the frog returns to its normal life.

Circulatory system
The frog's kidneys (2) are located dorsally, outside the body cavity in the sub-ventral lymph sinus.
Pithing targets the brain stem of the frog that is responsible for the involuntary functions of its body like the beating of the heart and breathing. It kills the frog so it can be dissecting properly. Etherizing is like an anesthesia that knocks its out so pithing cannot be felt.
A frog's heart is blue when it is inside of the frog. If the blood inside the heart oxidizes, the heart will be red.
Fertilisation takes place externally. The female produces frog spawn and the male fertilises the frog spawn outside the female's body.
Heart Liver Lungs Kidneys Brain
A frog's ventricle pumps blood out of the heart through its body. Our left ventricle does the same thingto pump out blood.
