The similarity is both of them use lung as the site for gaseous exchange. The difference is human heart has two ventricles while frog only has one. So the deoxygenated and oxygenated blood in frog are mixed together as its ventricle is not divided into two by septum, which is present in human.
Frog is in a phylum Chordata same as human which means they are very close and have similar structures in terms of taxonomic classification and embryological development. One of the differences would be they differ in classes.. frog is a class Retilia and human is in class Mammalia. One similarity between circulatory system of frog and human is that they are both closed circulatory systems which means the blood does not diffuse into cells directly like the open circulatory systems does. In terms of heart structure, reptiles have only 3 chamberd heart, 2 atria and 1 ventricle, while mammals like human have 4 chamberd heart, 2 atria and 2 ventricle. Is it only me think they have more differences than similarities? weird...
A human heartbeat remains the same regardless of the surrounding temperature. A frogs heart beat beats faster when the temperature increases.
Both have a heart and they both are a closed circualtroy system
There are many differences and similarities between a perch and a human in the digestive system. One is the enzymes found in the gut.
Because their circulatory system is very similar to ours. Also, the size of our hearts are very close.
similarities between kangaroo and human
There are very many similarities
The main similarities between koala and human digestive systems are the basic organs of oesophagus, stomach, liver, etc. Koalas have a different digestive system and metabolism which enables them to digest gum leaves. Eucalyptus leaves are tough, toxic and low in nutrition, but the koala has developed a stomach which is capable of removing the toxins from where they are filtered out by the liver. The caecum completes the process by changing the eucalyptus leaves into digestible nutrients. The caecum is similar to the human appendix.
The circulatory system of the chimp and human is basically the same.

There are many differences between cow's and human's circulatory systems. The cow system has to work around 4 stomachs for example.
Because their circulatory system is very similar to ours. Also, the size of our hearts are very close.

A human circulatory system.

similarities between kangaroo and human
Well,circulatory system is made up of BLOOD and heart.
A human
closed circulatory system
