The last one tells the maximum amount of air lungs can hold. The first one shows the quantity of air for a single function. There is a stark difference between these two terms. It is determined based on human breath, which is a full respiratory circle of one inspiration and expiration. Lung volumes and capacities are two significant terms in the respiratory system. Also, the lungs of a sparrow are different as they can fly. For example, the structure of a dog’s lungs is smaller than humans. However, the structure and capacities are different amongst various species. The lung is the primary respiratory organ of animals. On the other hand, lung capacity is the volume of air in the lungs upon the maximum effort of inspiration. Lung volume measures the amount of air present for a living being to inhale or exhale. Lung volume and lung capacity are used to measure air present in the lungs. It is a medical apparatus that is used to determine the amount of air you are able to breathe in and out and the time you take to completely exhale the air after you take a deep breath. The device that is used to measure the volume of air involved is called a spirometer. Also, the lung capacity of animals like cheetahs and gazelles is very high because they require a large amount of oxygen for their muscles in order to run at very high speed.Ī human lung has a capacity to hold a maximum of six litres of air. For example, the lung capacity of an elephant is greater than that of a human due to its large body size. In spite of the functionality, the structure and capacities are different amongst various species.ĭifferent animals have different lung capacities based on the size of the body and the activities they perform. Lungs are the primary respiratory organs of animals. In simple words, lungs remove carbon dioxide and bring oxygen to the blood. Lungs are a pair of organs located within the chest, which help in breathing.
