What Are The Lungs Inside Your Body?

The lungs are a pair of vital organs inside your chest that help you breathe and keep your body supplied with oxygen. They are a central part of the respiratory system and work continuously to support life.

A Brief Idea About The Left And Right Lungs

Both lungs do the main job of exchanging gases, but they have different shapes to make room for other organs in your chest.

➦ The Right Lung

  • Structure: It is shorter and wider than the lungs to make room for the liver.
  • Lobes: It has three lobes: the middle and lower lobes.
  • Fissures: It has two fissures, the oblique fissures that separate these three lobes.
  • Volume: It is generally heavier. Has a slightly larger air capacity than the left lung.
  • Bronchi: The right main bronchus is wider and vertical.

➦ The Left Lung

  • Structure: It is longer and narrower than the lung.
  • Lobes: It has two lobes: the upper and lower lobes.
  • Cardiac Notch: It features an indentation called the cardiac notch, which allows space for your heart.
  • Lingula: Of a middle lobe, it has a small tongue-like projection called the lingula on the upper lobe.
  • Fissures: It has one fissure, the oblique fissure.

Lungs – Their Functions And Role In Your Body

1. Primary Function

As you have read in textbooks from quite an early age, the main role that your pair of lungs plays is to help get the oxygen that you inhale each time.

In addition, of course that just one part, the lungs are holding the waste gases and harmful materials that you inhale out completing one cycle of respiration.

➦ Oxygenation: Every cell in your body needs oxygen to create energy.

➦ Waste Removal: As cells work, they produce carbon dioxide as a waste product.

Other Functions Of The Lungs That You Are Not Aware Of

It is not that the lungs only perform the art of gaseous exchange. Well, here are a few more roles played by your lungs that are probably not aware of until now:

  • Acid-Base Balance: Your lungs help keep your blood from becoming too acidic.
  • Mucociliary Clearance: Sticky mucus traps dust, smoke, and germs.
  • Immune Support: Specialized immune cells in the lungs “eat”. Destroy harmful bacteria.
  • Blood Pressure Control: The lungs produce an enzyme that helps regulate blood pressure.

A Few Interesting Facts About Lungs

  • Did you ever know that lungs can float in the air as the tissues and cells are so less dense?
  • The network of air sacs present in your lungs is quite big, well big enough that it may cover the entire length and breadth of a tennis court. Yes, that much amount of network of air sacs is present inside the pair of lungs.
  • You may be surprised to know that if you are to stretch the airways that are the network of bronchial trees it would run for 2400 kilometers.
  • Most people are not aware or breathe consciously. However, guess what you do this activity about 22,000 times a day.
  • A human can survive and lead almost a normal life even within a single lung performing.

What Is Inside Your Lungs?

Inside your lungs is a network of air passages, millions of microscopic air sacs, and a vast web of blood vessels. It typically contains different kinds of tissues, blood, lung fluids, and a vast network of nerves and of course the entire bronchial tree.

Types Of Cells Inside The Lungs

The cells contain types of cells in them like:

  • Type-1 pneumocystis
  • Type-2 pneumocystis
  • Alveolar macrophages
  • Parenchyma

Conditions And Disorders Affecting Lungs

Lung conditions are generally classified based on which part of the respiratory system they affect the airways, the lung tissue, or the blood circulation.

1. Airway Diseases

These mostly affect not airways, not necessarily the lung tissues. However, remember that airway also includes the bronchial network, which expands inside the lungs.

2. Lung Tissue Diseases

These are the diseases which necessarily affects the lung tissues inside the organ.

  • Pulmonary fibrosis
  • Sarcoidosis

3. Lung Circulation Disorders

These relate with mostly the arteries present in the lungs that are suffering from any abnormal or diseased condition.

  • Pulmonary arterial hypertension
  • Pulmonary embolism

4. Lung Infections

As the name speaks for itself these, do harmful microbes cause infections?

  • Pneumonia
  • Tuberculosis

5. Other Conditions

  • Lung cancer
  • Pneumothorax

Signs Of Lung Disorders And Infections

Common Signs of Lung Disorders

  • Mild or severe cough
  • Sudden feeling that you are out of breath
  • Wheezing
  • Severe mucus production
  • Weight loss
  • Clubbed fingers
  • Fevers
  • Yellowish mucus
  • Chest pain
  • Muscle ache
  • Severe fatigue

When To Get Emergency Help For Any Lung Issue?

Take immediate help from a doctor if you notice signs of-

  • Cyanosis
  • Severe difficulty in breathing
  • Feeling confused
  • Rapid rise in heartbeat

Diagnostic Tests To Reveal Lung Issues

1. Pulmonary Function Tests

2. Imaging Tests

  • Chest X-Ray
  • CT Scan
  • Chest Ultrasound

3. Laboratory & Blood Tests

  • Arterial Blood Gas
  • Pulse Oximetry

Lung Treatment Options

Treatment for lung conditions varies significantly based on whether the issue is an acute infection, a chronic disease, or a structural abnormality, like cancer.

➦ Use OF Medicine

Of course, this is one of the most basic and first-hand treatments that the doctors recommend. For any mild lung disorder or even an infection, a surgery is not recommended at first. Then there are different kinds of medicines, which can help treat a lung disorder or an infection like:

  • Antibiotics
  • Bronchodilators
  • Corticosteroids

➦ Therapies And Supportive Care

A therapy may be given to get rid of an emergency condition or even as a post-operative condition that is after a surgery. Remember that these are full-blown treatments and undergoing therapy does not mean that you are out of the danger.

  • Oxygen Therapy
  • Pulmonary Rehabilitation
  • Non-Invasive Ventilation

➦ Surgical And Advanced Procedures

Of course, it is up to the doctors, but when normal medicines or other therapies fail, the option is nothing else but surgery inside your lungs. Depending on the type of condition there are various surgeries performed inside your lungs.

  • Lung Resection
  • Lung Volume Reduction
  • Lung Transplant

FAQs

Q-1. What are the advanced lung surgeries done today?

Some of the complex and advanced lung surgeries done these days include-

  • Robotic surgery in the thoracic cavity
  • Tubeless surgeries
  • Tissue sparring resections.
  • Use of technology and assisted devices in breathing

Q-2. What are the basic lung care steps at home?

Basic lung care steps at home include having a correct lifestyle, which is to give up addictions. On top of that, you need a good and healthy diet along with plenty of exercise and yoga. Getting on time vaccines and immune shots is the way to avoid different lung infections.

Q-3. Can you tell me some exercises that keep my lungs in good shape?

Well, anyone can try out two basic lung exercises anytime like pursed lip breathing and diaphragmatic breathing.
