Left Ventricle vs. Right Ventricle

The main difference between the left ventricle and right ventricle is that left ventricle develops more pressure as compared to the right ventricle.

What is Left Ventricle?

The left ventricle is one of four chambers of the heart. It is situated in the base left part of the heart underneath the left chamber, isolated by the mitral valve. As the heart contracts, blood in the long run streams once more into the left chamber, and after that through the mitral valve, after that it next enters the left ventricle. From that point, blood is pumped out through the aortic valve into the aortic curve and ahead to whatever is left of the body. The left ventricle is the thickest of the heart’s chambers and is in charge of pumping oxygenated blood to tissues everywhere throughout the body. By difference, the right ventricle exclusively pumps blood to the lungs. Different conditions may influence the left ventricle and meddle with its legitimate working. The most well-known are left ventricular hypertrophy, which causes development and solidifying of the muscle tissue that makes up the mass of the left ventricle, as a rule as an aftereffect of uncontrolled hypertension. Another condition that may affect this range is left ventricular noncompaction cardiomyopathy, in which the muscle tissue encompassing the left ventricle is springy or “non-compacted;” in any case, this condition is uncommon.

What is Right Ventricle?

The right ventricle is equivalent in size to that of the left ventricle and contains approximately 85 milliliters in the grown-up. Its upper front surface is surrounded and raised, and frames a significant part of the sternocostal surface of the heart. It’s under the surface is straightened, framing part of the diaphragmatic surface of the heart that rests upon the stomach. It’s back divider is framed by the ventricular septum, which swells into the right ventricle so that a transverse area of the pit displays a semilunar diagram. Its upper and left edge shape a funnel-shaped pocket, the conus arteriosus, from which the aspiratory course emerges. A tendinous band called the ligament of the conus arteriosus develops upward from the privilege atrioventricular sinewy ring and interfaces the back surface of the conus arteriosus to the aorta. The right ventricle is triangular fit as a fiddle and reaches out from the tricuspid valve in the right chamber to close to the zenith of the heart. Its divider is thickest at its base and diminishes towards the chamber. The right ventricle gets deoxygenated blood from the right chamber through the tricuspid valve and pumps it to the fundamental aspiratory supply route. The pneumonic corridor, which reaches out from the right ventricle, promote stretches out to one side and right aspiratory supply routes. By coursing into the aspiratory supply routes, the deoxygenated blood grabs oxygen from the lungs before it flows to the one hand chamber.

Key Differences

  1. The left ventricle is round shaped while right ventricle is pouch-shaped.
  2. The left ventricle has very thick myocardium and wall while right ventricle has thinner myocardium and wall.
  3. Right ventricle has lower pressure system. Left ventricle produces four to six times as much pressure than right.
  4. Right ventricle receives deoxygenated blood from the right atrium through the tricuspid valve. Left ventricle receives oxygenated blood from the left atrium through the mitral valve.
  5. The right ventricle pumps blood to the pulmonary circulation through the pulmonary arteries while left ventricle pumps blood to the systemic circulation through the aorta.
  6. The right ventricle is triangular in shape and located near the apex of the heart. The left ventricle is oval in shape and forming the apex of the heart.
  7. Right-sided heart failure occurs in response to left-sided failure.
  8. The ratio of left to right ventricular is 3:1, the reason being the difference in the resistance of the two circulations.
  9. The ventricular septum is also mildly covexed towards the right side.
  10. Left ventricle also forms the apex of the heart.
  11. Left ventricular is more muscular than right ventricle because it pumps the blood at a higher pressure.
  12. Left ventricle pump out blood to almost whole blood while right ventricle pumps out blood to the lungs.
