Detailed Structure of Frog's Heart - Microbiology Notes Heart of frog is three chambered. It is dark red colored conical muscular organ situated mid-ventrally in the anterior part of the body cavity in between two lungs. The heart is enclosed in two membranes- an inner epicardium and outer pericardium. The space between these two layers is called pericardial cavity.
