heart attack
Why does the frog heart have lower heart rate than mammalian heart?
Frog's internal body temperature is lower than that of a mammal lower temperature = slower heart rate
What happens when the heart relaxes?
It is in its diastolic phase.
What happens when the heart rate increases during a hot bath?
you might have a heart palpatation
Would you expect to see similar changes in heart rates in human cardiac muscle and frog cardiac muscle with environmental temperature changes?
No. Frogs are not mammals nor endothermic, which is why they change their heart rate and temperature to match their surroundings. Humans regulate their body temperature and heart rate at a steady rate no matter what their surroundings are.

Why does a birds heart work better than a frogs?
Birds have a 4- chambered heart so the blood doesn't mix Frogs have a 3- chambered heart so the blood mixes
How do frogs and tadpole hearts differ?
Tadpoles have a two-chambered heart similar to fish. Frogs have three-chambered heart, which tadpoles develop when they grow into a frog.
What kind of blood leaves the ventricle of the frogs heart?
The blood that leaves the frogs heart through the ventricles is almost pure blood. This blood goes to the brain.
