The respiratory system helps you breathe, providing oxygen to your body and removing carbon dioxide. It includes organs that support both air intake and gas exchange.
🫁 Major Respiratory Organs
🏷️ Organ
📋 Function
👃 Nose/Nasal Cavity
Filters, warms, and moistens incoming air
🧵 Pharynx
Passageway for air and food
🔔 Larynx (Voice Box)
Produces sound and protects the trachea
🌬️ Trachea
Windpipe that connects throat to lungs
🌳 Bronchi
Two air tubes that branch into the lungs
🍃 Lungs
Site of oxygen–carbon dioxide exchange
🎈 Alveoli
Tiny air sacs where gas exchange happens
🩸 Diaphragm
Muscle that controls breathing movements
😷 Common Respiratory Diseases
🚨 Condition
📝 Description
🌫️ Asthma
Airways become inflamed and narrow (triggers include dust, pollen, etc.)
🦠 Pneumonia
Lung infection that fills alveoli with fluid
🧬 COPD
Chronic lung damage, includes bronchitis & emphysema
💨 Bronchitis
Inflammation of bronchial tubes
🧫 Tuberculosis (TB)
Bacterial lung infection
😮💨 Sleep Apnea
Breathing stops during sleep
🫁 Lung Cancer
Uncontrolled cell growth in lung tissues
🧊 Common Cold & Flu
Viral infections affecting the upper airway
🔬 Diagnostic Tests
📷 Chest X-ray – Imaging lungs for infections or tumors
💨 Spirometry – Tests lung function (airflow)
🔬 Sputum Test – Identifies infections from coughed-up mucus
🧪 Blood Gas Test – Measures oxygen & carbon dioxide levels
📉 Oximeter – Measures oxygen saturation in blood
🛡️ Respiratory Health Tips
🚭 Quit smoking — #1 lung health risk
🧼 Practice good hygiene to prevent infections
🏃 Exercise regularly to strengthen lungs
😷 Wear a mask in polluted environments
🛌 Get vaccinated (flu, pneumonia, COVID-19)
🍃 Breathe clean air — avoid dust and chemical exposure
