बीड़ी या सिगरेट से फेफड़े कैसे खराब होते हैं । How Smoking Destroys Your Lungs / Lung Cancer #viral

Myself Dr. Vakeel Khan, and in this video, I have explained in detail about बीड़ी या सिगरेट से फेफड़े कैसे खराब होते हैं — How Smoking Destroys Your Lungs. I have discussed how the harmful substances in smoke such as निकोटीन (Nicotine), तार/राल (Tar), and कार्बन मोनोऑक्साइड (Carbon Monoxide) directly affect the respiratory system. Starting from the Oral Cavity (मुखगुहा) and Pharynx (ग्रसनी/गला), the smoke travels through the Trachea (श्वासनली) into the Right and Left Bronchus (दायां व बायां ब्रोंकस), reaching deep into the Alveoli (वायुकोष) of the Right and Left Lungs (दायां व बायां फेफड़ा). Here, the lungs get exposed to over 70 carcinogens (70 कैंसरकारी तत्व) present in cigarette smoke. This damages the delicate lung tissue and reduces oxygen exchange, putting strain on the Heart (हृदय) as well. I’ve also explained the dangers of Passive Smoking (अप्रत्यक्ष धूम्रपान / पैसिव स्मोकिंग), which harms even those who don’t smoke directly. This video gives a complete understanding of how smoking gradually destroys your lungs and overall health. #trending #trendingvideo #lungcancer #smokingcigars #viralvideo
