This extra space on the left leaves room for your heart. Your lungs are protected by your rib cage, which is made up of 12 sets of ribs.
Why is the right lung bigger than the left?

Why is the left lung smaller than the right lung quizlet?
The left lung is slightly smaller than the right lung because 2/3 of the heart is located on the left side of the body . ... The smaller left lung only has 2 lobes – superior and inferior – separated by the left oblique fissure.
Can you live with one lung?
Most people can get by with only one lung instead of two, if needed. Usually, one lung can provide enough oxygen and remove enough carbon dioxide, unless the other lung is damaged. During a pneumonectomy, the surgeon makes a cut (incision) on the side of your body.
Do lungs help blood get around your body?
Blood with fresh oxygen is carried from your lungs to the left side of your heart, which pumps blood around your body through the arteries . Blood without oxygen returns through the veins, to the right side of your heart.

Why do we have two lungs?
There is also a structural advantage to having the lungs be separate , the main one being that the bronchial tubes bifurcate naturally, and that there is a place for the heart and other “indivisible” organs in the middle. Separation also decreases the chance of problems or disease in one spreading to the other.
Which side lungs is bigger?
A person's lungs are not the same size. The right lung is a little wider than the left lung , but it is also shorter.

Where is the position of the lungs in human body?
The lungs are located on either side of the breastbone in the chest cavity and are divided into five main sections (lobes). The lungs are responsible for removing carbon dioxide from the blood and adding oxygen to it. The heart and lungs work together to do this.
What stops food going into lungs?
When you breathe, air enters your mouth and moves into the pharynx. The air then goes down into your main airway (trachea) and into your lungs. A flap of tissue called the epiglottis sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow.
What are the structural differences between the left and right lung?
The right and left lungs differ in size and shape to accommodate other organs that encroach on the thoracic region . The right lung consists of three lobes and is shorter than the left lung, due to the position of the liver underneath it. The left lung consist of two lobes and is longer and narrower than the right lung.
Why is lung compliance important?
Lung compliance participates in the lung-chest wall system by opposing the outward pull of chest wall compliance. The net compliance (lung-chest wall system) allows the lungs to achieve appropriate functional residual capacity , the volume remaining after passive expiration.
What are two anatomical differences between the left and right lungs?
Right lung is wider and shorter whereas left lung is narrower and longer. Right lung consists of three lobes whereas left lung consists of two lobes. The main difference between right lung and left lung is that the anterior border of the left lung consists of a deep cardiac notch whereas right lung is straight .
