Atria act as receptors of deoxygenated blood, while ventricles receive blood from the left atria and force it into the aorta. Atria have strictly to do with the inner chambers of the heart, while ventricles may even refer to the interconnected brain cavities. The walls of the atria are thinner with low blood pressure, while those of the ventricles are thicker with high blood pressure.

The right ventricles open into the right ventricles through the tricuspid valve, and the left auricle opens into the left ventricle through the mitral valve. There are some specialized cells in the auricular region called the sinoatrial node and the pacemaker cells.
The sinoatrial node generates impulses that set a normal rhythm and rate of the heart. That is why it is also called the natural pacemaker of the heart. The ventricle is the singular for the ventricles that refers to the lower half of the heart. The lower divisions of the heart are separated by the interventricular septum. The left ventricle receives fresh blood from the auricles, and it pumps it to the rest of the body from the right ventricle through the aorta.
Oxygenated blood from the heart is transported to all parts of the body from the heart through various arteries and systems. Since the distance of blood flow is large from the heart to the lower portion of the body or the kings this the blood pressure in this chamber is high, and its walls are highly muscular and thick.
Because the ventricle uses a large amount of pressure to pump blood hence, we can feel our heartbeat slightly towards the left, where the pumping is the hardest. The right ventricle opens into the pulmonary artery through the semilunar valve, and the left ventricle opens into the aorta through the aortic valve. Due to more function and power required, it is also bigger. It has special fibres called Purkinje fibres that conduct electrical impulses throughout the ventricles. The proper functioning of each of the chambers of the heart is necessary for uniform blood circulation.
Hence muscle mass around ventricles is thickened compared to that around atria. Stimulus for rhythmic contraction of heart originates inside auricular wall due to presence of sinoatrial node. Moreover, myocardium of both atria together form a functional syncytium and it remains completely separated from ventricular myocardial syncytium. Is there any difference between the wall of atria and the wall of ventricles? Mandira P. Mar 15, Explanation: Atria of heart are receiving chambers while ventricles pump the blood forcefully to all organs of body.
