FAQs on Fun video: Immunity, Innate Immunity (Part - 3) Video Lecture - NEET
| 1. What is innate immunity? |  |
Ans. Innate immunity refers to the body's natural defense mechanisms that are present from birth. It is the first line of defense against pathogens and does not require prior exposure to the specific pathogen. Innate immunity includes physical barriers like the skin, chemical barriers like enzymes and acids, and cellular defenses like phagocytes.
| 2. How does innate immunity differ from adaptive immunity? | |
Ans. Innate immunity is the immediate response of the body to any foreign substance, while adaptive immunity takes time to develop and involves the production of specific antibodies against a particular pathogen. Innate immunity is nonspecific, meaning it targets a wide range of pathogens, whereas adaptive immunity is highly specific to a particular pathogen.
| 3. What are the physical barriers of innate immunity? | |
Ans. Physical barriers of innate immunity include the skin, which acts as a physical barrier preventing pathogens from entering the body. Other physical barriers include mucous membranes lining the respiratory, gastrointestinal, and urogenital tracts, which produce mucus that traps pathogens, and cilia that help move the trapped pathogens out of the body.
| 4. How do chemical barriers contribute to innate immunity? | |
Ans. Chemical barriers play a crucial role in innate immunity by producing substances that can kill or inhibit the growth of pathogens. Examples of chemical barriers include enzymes in body fluids like tears and saliva, which can break down the cell walls of certain bacteria, and acids in the stomach that kill many ingested pathogens.
| 5. What are phagocytes and their role in innate immunity? | |
Ans. Phagocytes are a type of white blood cell that plays a key role in innate immunity. They are responsible for engulfing and destroying pathogens, dead cells, and other foreign substances. Phagocytes recognize and bind to pathogens, then internalize them into specialized compartments called phagosomes, where they are broken down and destroyed.
