Difference between Right and Left Lung




  • Main Difference

    The right side of the pair of organs, the principal parts of the respiratory system, at the front of the cavity of the chest, or thorax becomes known as right lung.  The left side of the pair of organs, the principal parts of the respiratory system, at the front of the cavity of the chest, or thorax becomes known as the left lung.

    Basis of Distinction Right Lung Left Lung
    Definition The right side of the pair of organs, at the front of the cavity of the chest, or thorax. The left side of the pair of organs, the principal parts of the respiratory system, at the front of the cavity of the chest, or thorax.
    Lobes It has three different lobes known as a superior, middle and inferior lobe. The number of lobes present within the left lungs are two and have the names of upper and lower.
    Size Shorter and wider part of the body. A bigger size but narrower than the other.
    Fissures It has an oblique fissure. It has both the oblique and horizontal fissure.

    Right Lung

    The right side of the pair of organs, the principal parts of the respiratory system, at the front of the cavity of the chest, or thorax becomes known as right lung. The right lung has three projections called upper, center and lower flaps. The air that we take in enters the nose or mouth, moves through the throat called pharynx and voice box called larynx and enters the windpipe called trachea. The trachea partitions into two empty tubes called bronchi. The correct fundamental where bronchus is the word for one of the bronchi supplies the right lung; the left primary bronchus supplies the left lung. These bronchi then go ahead to partition into littler bronchi. The small bronchi partition into littler and littler empty tubes which are called bronchioles – the littlest air tubes in the lungs. The restorative term for all the air tubes from the nose and mouth down to the bronchioles is ‘the respiratory tract.’ The lower respiratory tract is from the larynx. A man’s lungs are not a similar size. The right lung is somewhat more extensive than the left lung. However, it is likewise shorter. The right lung is shorter because it needs to prepare for the liver, which is appropriate underneath it. The left lung is smaller because it must account for the heart. Commonly, a man’s lungs can hold more air than a woman’s. Very still, a man’s lungs can hold around 750 cubic centimeters of air while ladies can hold around 285 to 393 cc of air.

    Left Lung

    The left side of the pair of organs, the principal parts of the respiratory system, at the front of the cavity of the chest, or thorax becomes known as the left lung. The left lung just has two flaps, the upper and lower. The lungs are among the most diligent organs in the body. They extend and contract up to 20 times each moment to supply oxygen to be circulated to tissues everywhere throughout the body and oust carbon dioxide that has been made all through the body. Every lung houses a bronchial tree, which gets its name from the compound system of air sections that supply the lungs with air. The air-filled sacs in the lungs called alveoli take after grape groups. White platelets known as macrophages, situated inside every alveolus, ingest and wreck airborne aggravations that enter the lungs. After you breathe out, the lungs remain incompletely expanded because of a liquid called surfactant that is delivered by exceptional cells and discharged inside the alveoli. Surfactant contains greasy proteins and anticipates lung diseases. The cerebrum controls the essential cadence of breathing. Some portion of the mind called the brainstem has an extraordinary zone committed to keeping up your breathing example. Nerve motivations from the brainstem control the constrictions of your stomach and other muscles of relaxing. It altogether gets managed without considering. In any case, different parts of the cerebrum can briefly overrule the brainstem. It is how we are capable deliberately of holding our breath or changing our example of relaxing.

    Key Differences

    • The right side of the pair of organs, the principal parts of the respiratory system, at the front of the cavity of the chest, or thorax becomes known as right lung. On the other hand, the left side of the pair of organs, the principal parts of the respiratory system, at the front of the cavity of the chest, or thorax becomes known as the left lung.
    • The number of lobes present in the two lungs makes for the main difference between them. The right lung has three different nodes known as a superior, middle and inferior lobe. On the other hand, the number of nodes present in the left lungs are two and have the names of upper and lower.
    • The structure of both the lungs also has different nature. While the right lung has a shorter and wider part of the body, the left lung has a bigger size but narrower than the other.
    • The reason why both the lungs do not have the same size becomes the thick cardiac notch present within the left lung border and gives it the distinction, whereas it does not have any role in the right lung.
    • The left lung has an oblique fissure whereas the right lung has both the oblique and horizontal fissure.
