List of Facts About Lungs

Pulmonology is the study of the lungs, including their structure, function, and associated diseases.

Here are some fascinating facts about the lungs:

Fact 1

The lungs are the main organs of the respiratory system. A average human breathes approximately 13 quarts of air every minute.

Fact 2

The normal adult’s lungs hold about 6 litres of air. However, during regular breathing, only around 10% of this capacity is used.

Fact 3

The right lung is larger than the left lung, and its combined surface area is 80 square metres, almost similar to the size of a tennis court.

Fact 4

The lungs are the only organs in the human body capable of floating on water.

Fact 5

Humans have two lungs, which are placed in the thoracic cavity of their chest. The trachea is divided into smaller structures called bronchi, which are further divided into bronchioles.

Fact 6

Regular physical activity may improve lung capacity, lowering the risk of lung disease while also allowing air to enter the body more easily and quickly through the lungs.

Fact 7

The lungs receive a huge volume of blood about 5 litres per minute to aid in gas exchange. The pulmonary arteries carry blood from the heart to the lungs, and the pulmonary veins return oxygenated blood to the heart.

Fact 8

The lungs have several defence systems in place to keep foreign particles and pathogens out of the respiratory system. Nasal hairs, mucus, and cilia (tiny hair-like structures) all help catch and remove debris from the airways.

Fact 9

Tobacco usage significantly increases the risk of developing lung cancer and other lung-related illnesses. Smoking passively increases your risk of acquiring lung cancer, coronary artery disease, and stroke.

Fact 10

Lung cancer is one of the most common cancers worldwide, and it is commonly associated with smoking. Nonsmokers, on the other hand, may develop lung cancer as a result of secondhand smoke, air pollution, or a hereditary susceptibility.

Fact 11

Asthma is one of the most common and serious respiratory ailments. This type of lung illness arises when the airways constrict after being irritated, making it more difficult to breathe.

Fact 12

Bronchitis, asthma, pneumonia, and chronic obstructive pulmonary disease are examples of lung-related respiratory illnesses.

Fact 13

In the breathing process, inhalation is far more strong than exhalation. When we breathe in, the nasal chambers filter the air. As a result, it is preferable to breathe in and out via your nose rather than your mouth.

Fact 14

The lungs defend against infections and diseases through mechanisms like the mucociliary escalator, which traps and removes pathogens, and immune cells like macrophages, which engulf and destroy invaders. These defenses help maintain lung health and prevent respiratory infections.

Fact 15

Yawning allows us to obtain more oxygen into our lungs. It is an involuntary procedure that involves a lengthy inhale (or inspiration). This process begins when the brain sends a message suggesting a lack of oxygen, causing our sensory system to take a long deep breath or yawn.

The lungs are crucial organs in the respiratory system that control breathing. The lungs function by taking in oxygen from the air and releasing carbon dioxide, helping to oxygenate the blood and remove waste gases from the body. The lungs are part of the human respiratory system, which functions till the end of our lives. All other animals and birds lack specialized lungs, whereas humans have.
