The heart is ALWAYS a part of the circulatory system.
The heart is a muscle, but it is NOT in the muscular system, and pumps blood to all parts of the body :)
Frog's internal body temperature is lower than that of a mammal lower temperature = slower heart rate
A frog heart can never reach tetanus.
the cooler the frog the slower the heart rate, the warmer the faster
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.
Circulatory system
The pancreas of a frog belongs to the digestive system
The heart is a muscle, but it is NOT in the muscular system, and pumps blood to all parts of the body :)
the heart is the main circulatory organ of the frog
The pericardium is the sac surrounding the frog's heart.
Frog's internal body temperature is lower than that of a mammal lower temperature = slower heart rate
The digestive system of the frog feeds into the cloaca. This is how the frog excretes waste from it's system.
The digestive system.
I believe that the frog heart has one large chamber. When the "dirty" blood returns to the heart from nourishing the body, it mixes with the newly oxygenated blood from when the frog breathed. This type of heart is not as efficient as other animals with chambers to keep the two kinds of blood "dirty" and oxygenated separated. The frog still gets rid of waste gas and pumps fresh gas to its body but some of the waste blood gets pushed around the body too. The frog blood contains a lower concentration of pure gas blood than other animals.
A frog has a liver, stomach, reproductive system, somewhat nuerological, and mucle/fat tissues similar to us.
I think it is part of the digestive system.
The system is the egg then the legs then the hands then the big body
