The frog heart differs from the mammalian heart anatomically in that they are three chambered rather than four chambered. The pacemaker in the amphibian heart is the sinus venosus, a thin-walled sac that receives blood from the anterior and posterior caval veins and empties blood into the right atrium. The single ventricle receives blood from both atria and pumps blood out through the large artery called the truncus arteriosus (Figure 1). In contrast, the mammalian ventricle has separate left and right chambers, which prevent mixing of the venous and arterial blood.

What are the differences between the concentrated gases of a fish heart and a human heart?
The fish heart typically has a two-chambered structure with one atrium and one ventricle, while the human heart has a four-chambered structure with two atria and two ventricles. Fish hearts also have lower pressure and flow rates compared to human hearts, which reflects the differences in the circulatory systems and oxygen demands between the two species.
Similarities between the human and rat digestive tract?
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.
