Human lungs are divided into right and left lungs, and further subdivided into lobes. The right and left lung are not symmetrical, since your right lung has three lobes and your left lung has two. The lobes on both sides of your lungs are separated by fissures.

How many tertiary bronchi are there in the human lung?
There are 10 tertiary bronchi in the right lung and 9 in the left, so each of the lung segments is supplied by one of these bronchial branches [11]. The tertiary bronchi further branch into bronchioles to finally lead the inhaled air into the alveoli [12].
Why is the left lung smaller than the right?
The left lung is a little smaller than the right lung because it has to make space for the heart (the cardiac notch) in the left side of the thoracic cavity. As a result, the right lung is larger, having three lobes, while the left one only has two [4].

Only the right lung has a middle lobe.
Why is the left lung smaller than the right?
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.

What is the left lung?
The left lung shares space with the heart, and has an indentation in its border called the cardiac notch of the left lung to accommodate the heart. It is divided into two lobes, an upper and a lower, by the oblique fissure, which extends from the costal to the mediastinal surface both above and below the hilum. The left lung, unlike the right, does not have a middle lobe, though it does have a homologous feature, a projection of the upper lobe termed the "lingula". Its name means "little tongue". The lingula on the left serves as an anatomic parallel to the right middle lobe, with both areas being predisposed to similar infections and anatomic complications.

As the pleura holds,there are several blood vessels,lymphatic vessels and bronchi which goes in and goes out. The left lung is slighty different in size and shape from the right as the left lung is around 10% smaller. But do take note as because the left lung contain a concavity in which the cardiac notch is located whereby the heart lies there.This cardiac notch occupy the space at the left lung region. However,the right lung is somewhat shorter than the left lung because the diaphragm is located higher on the right side to accomodate the liver.

What is the smallest tube in the lungs?
Within the lungs, these bronchi are divided into smaller tubes. The smallest of these tubes is called a bronchiole. Bronchioles control the exchange of gases with the alveoli, which are tiny air sacs in the lungs. Each lobe of the lung has the same physiologic function, bringing oxygen into the bloodstream and removing carbon dioxide.
Where is the bronchial lobe located?

How many lobes does the left lung have?
Unlike the right lung, the left lung has only two lobes instead of three, the upper and the lower. It is divided by a deep oblique fissure. With the heart close to the left lung, it partly compresses the anterior border of the left lung and so makes it comparatively smaller than the right lung. While it does not have a middle lobe like the right lung, it does have its ‘lingula’ (little tongue), a tongue-like projection on the superior lobe.
