What is the main function of the lungs?

The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.

Likewise, people ask, why do we have 3 lobes in the right lung?

The left lung is smaller because of the space taken up by the heart (see diaphragm for an image of this). Each lung is separated into lobes branching off the main bronchus; the right lung has three lobes, while the left has only two lobes. The lungs are "stuck" to the inside of the thorax, also by surface tension.

Why are each side of the lungs divided into lobes?

Human lungs are located in two cavities on either side of the heart and are separated into lobes by fissures. The right lung is divided by the oblique fissure, which separates the inferior lobe from the middle and superior lobes, and the horizontal fissure, which separates the superior from the middle lobe.

How many lobes do you have in your lungs?

The right lung (the larger of the two) has 3 lobes. The horizontal fissure separates the superior lobe from the middle lobe, while the right oblique fissure separates the middle and inferior lobes. The smaller left lung only has 2 lobes. These two lobes are separated by the left oblique fissure.
