Health means being fit physically, mentally, and socially. Diseases are of two types: • Infectious (spread from person to person, like cold or AIDS) • Non-infectious (don’t spread, like cancer). Our body fights diseases using its immune system. Understanding Innate Immunity: Your body has natural shields called innate immunity present from birth. It includes: • Physical barriers like skin and inner body lining (mucosa) • Physiological barriers like stomach acid, tears, and saliva • Cellular barriers where germ-eating cells (like neutrophils) destroy invaders • Cytokine barriers, where virus-infected cells release "helper proteins" (interferons) to protect nearby cells. Acquired Immunity: Acquired immunity develops over time, remembers specific germs, and acts faster during repeat infections. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 📌 𝐅𝐫𝐨𝐦 𝐂𝐨𝐧𝐟𝐮𝐬𝐢𝐨𝐧 𝐓𝐨 𝐒𝐞𝐥𝐞𝐜𝐭𝐢𝐨𝐧:- 🞂 One Counselling for NEET 2025: https://applink.adda247.com/d/Counsel... 🞂 One Pro Counselling for NEET 2025: https://applink.adda247.com/d/Counsel... 📞 CALL NOW: 𝟎𝟕𝟎𝟒-𝟐𝟓𝟕-𝟖𝟐𝟒𝟕 for any Enrollment Queries. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 📌 𝐉𝐨𝐢𝐧 𝐍𝐂𝐄𝐑𝐓 𝐍𝐄𝐄𝐓 𝐀𝐝𝐝𝐚𝟐𝟒𝟕 𝐒𝐨𝐜𝐢𝐚𝐥 𝐌𝐞𝐝𝐢𝐚 𝐅𝐨𝐫 𝐍𝐨𝐭𝐞𝐬, 𝐐𝐮𝐢𝐳𝐳𝐞𝐬, 𝐒𝐭𝐮𝐝𝐲 𝐌𝐚𝐭𝐞𝐫𝐢𝐚𝐥 & 𝐌𝐨𝐫𝐞:- 🌐 Telegram: https://t.me/Ncertneetadda247 🌐 Instagram:   / ncert.adda247   📲 Download ADDA247 App: http://bit.ly/466MKQ3 ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 📌 𝐀𝐁𝐎𝐔𝐓 𝐍𝐂𝐄𝐑𝐓 𝐍𝐄𝐄𝐓 𝐀𝐃𝐃𝐀𝟐𝟒𝟕:- Welcome to Adda247, India's Largest Vernacular Learning Platform.
