FAQs on Immunity: Allergies Video Lecture - Capsule course of Zoology for NEET
| 1. What is the immune system? |  |
Ans. The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens, such as bacteria, viruses, and parasites. It is responsible for identifying and eliminating these foreign substances to maintain the body's health.
| 2. What are allergies? | |
Ans. Allergies are hypersensitive reactions of the immune system to substances that are usually harmless, such as pollen, dust mites, animal dander, or certain foods. When a person with allergies comes into contact with these allergens, their immune system overreacts, leading to symptoms like sneezing, itching, watery eyes, and skin rashes.
| 3. How does the immune system relate to allergies? | |
Ans. Allergies occur when the immune system mistakenly identifies harmless substances as threats and launches an immune response against them. The immune system releases chemicals, such as histamine, to fight off the perceived threat, causing the characteristic allergy symptoms. In individuals without allergies, the immune system does not react to these substances in the same way.
| 4. Can allergies be prevented? | |
Ans. While allergies cannot be completely prevented, there are measures that can help reduce the risk or severity of allergic reactions. These include minimizing exposure to allergens, keeping indoor environments clean, using air filters, avoiding known triggers, and taking prescribed medications as directed by a healthcare professional.
| 5. How can the immune system be strengthened to prevent allergies? | |
Ans. Strengthening the immune system can help reduce the likelihood of developing allergies. This can be achieved by maintaining a healthy lifestyle, including a balanced diet rich in fruits and vegetables, regular exercise, adequate sleep, stress management, and avoiding smoking or excessive alcohol consumption. Additionally, vaccinations and proper hygiene practices can also support immune system health.
