The wall of heart consists of three layers- outer epicardium, middle mesocardium and inner endocardium. It is long broad and thick walled structure. Both auricles open into ventricles by a common large auriculo-ventricular aperture. A frog's heart contains just three chambers, whereas a human heart has four chambers. However, from the left systemic arch, an additional branch is given off, the oesophageal which is absent in right side. Number of chambers in heart: 2 (1 atrium and 1 ventricle) Species: Frog (amphibian) Number of chambers in heart: 3 (2 atria and 1 ventricle) Species: Lizard (Reptiles) All of the chambers are near identical as an insect's heart is extremely simple compared to a human heart and is in essence a modified dorsal blood vessel. On the contraction of sinus venosus, the non-oxygenated venous blood is forced into the right auricle through sinu-auricular aperture. The linear heart tube is patterned along the anterior-posterior axis to form the future regions of the 4-chambered heart. As the contraction of ventricle initiates, firstly, the deoxygenated blood from the right side being nearer, flows into the truncus arteriosus. sinus venosus and truncus arteriosus. A very faint longitudinal inter-auricular groove demarcates the two auricles externally. The heart is enclosed in two membranes- an inner epicardium and outer pericardium. It is formed by the brachial from forelimb and the musculo-cutaneous from side of body and head. Explain the general characters of reptilia with respect to respiration, excretion, and reproduction.

At first, the tube-like heart is much like a fish heart. These valves allow the flow of blood towards right auricles but prevent backward flow of blood. One of the most important is the sub-vertebral lymph space above kidneys. The chordae tendinae pull the flaps backward to close the opening and thus prevent the valves from the backward flow of blood into the auricles. The heart is enclosed in two membranes- an inner epicardium and outer pericardium. It is most important part of the heart.
