Lungs & Breathing

See how breathing works and exactly what each condition changes — in interactive 3D with a live breathing trace — then find care.

Conditions in this section

• Asthma — The airways tighten, swell and fill with mucus — making breathing wheezy and hard, but very controllable.
• COPD (Chronic Lung Disease) — Long-term airflow blockage from damaged airways and air sacs — driven by smoke and air pollution.
• Tuberculosis (TB) — A curable airborne bacterial infection of the lungs — India’s biggest infectious challenge, free to treat.
• Pneumonia — An infection floods the air sacs with fluid and pus, so the lungs can’t take in oxygen — often treatable.
• Lung Cancer — Cells in the lung grow out of control — the leading cancer killer, but new treatments are changing the outlook.
• Pulmonary Embolism (Lung Clot) — A blood clot travels to the lung and blocks its blood flow — a true emergency, but very treatable in time.
