Questions

1. What is the primary function of the immune system?
Answer: Defend against infections and diseases
Explanation: The primary function of the immune system is to defend the body against infections and diseases caused by pathogens like bacteria, viruses, and fungi.Report for correction
2. What are the two main types of immunity in the human body?
Answer: Innate and adaptive immunity
Explanation: The two main types of immunity in the human body are innate immunity (present from birth) and adaptive immunity (developed in response to specific pathogens).Report for correction
3. Which type of immune cells are responsible for the immediate response to infections and are considered the first line of defense?
Answer: Macrophages
Explanation: Macrophages are immune cells that play a crucial role in the innate immune response and act as the first line of defense against infections.Report for correction
4. What is the main function of antibodies?
Answer: To neutralize pathogens
Explanation: Antibodies (immunoglobulins) are proteins produced by B cells that neutralize pathogens by binding to them, making them harmless and tagging them for destruction.Report for correction
5. Which type of immunity is developed after recovering from an infection or receiving a vaccine?
Answer: Adaptive immunity
Explanation: Adaptive immunity is developed after recovering from an infection or receiving a vaccine, and it provides a specific and long-lasting defense against the pathogen.Report for correction
6. What is the primary function of T cells in the immune system?
Answer: Destroy infected cells and cancer cells
Explanation: T cells play a crucial role in the immune system by recognizing and destroying infected cells, as well as cancer cells.Report for correction
7. What is the role of memory cells in the immune system?
Answer: Remember previous infections and respond faster upon re-exposure
Explanation: Memory cells are a type of immune cell that "remembers" previous infections and allows the immune system to respond more quickly and effectively upon re-exposure to the same pathogen.Report for correction
8. Which immune cells are responsible for coordinating the immune response and producing cytokines?
Answer: T cells
Explanation: T cells play a central role in coordinating the immune response and producing cytokines, which are signaling molecules that help regulate immune activity.Report for correction
9. What is the function of the thymus gland in the immune system?
Answer: Mature T cells
Explanation: The thymus gland is responsible for maturing T cells, which are important components of the immune system.Report for correction
10. Which type of immunity is acquired through breastfeeding and does not involve active immune responses?
Answer: Passive immunity
Explanation: Passive immunity is acquired through the transfer of antibodies or immune cells from one individual to another, as occurs during breastfeeding or through the administration of pre-formed antibodies.Report for correction
11. What is the term for the deliberate exposure to a weakened or inactive pathogen to stimulate an immune response and provide protection?
Answer: Vaccination
Explanation: Vaccination involves the deliberate exposure to a weakened or inactive pathogen to stimulate an immune response and provide protection against future infections.Report for correction
12. Which type of immune cells are involved in allergic reactions and asthma?
Answer: Eosinophils
Explanation: Eosinophils are immune cells that play a role in allergic reactions and asthma, particularly in response to allergens.Report for correction
13. What is the term for the process of immune cells engulfing and digesting pathogens?
Answer: Phagocytosis
Explanation: Phagocytosis is the process by which immune cells engulf and digest pathogens, such as bacteria and viruses.Report for correction
14. Which of the following is an autoimmune disease?
Answer: Diabetes mellitus type 1
Explanation: Diabetes mellitus type 1 is an autoimmune disease in which the immune system mistakenly attacks and destroys insulin-producing cells in the pancreas.Report for correction
15. What is the term for the ability of the immune system to distinguish between self and non-self antigens?
Answer: Immune tolerance
Explanation: Immune tolerance is the ability of the immune system to distinguish between self-antigens (components of the body) and non-self antigens (foreign invaders) to avoid attacking healthy tissues.Report for correction
16. Which type of immunity is typically short-lived and provides immediate protection?
Answer: Innate immunity
Explanation: Innate immunity provides immediate, but often short-lived, protection against a wide range of pathogens and is present from birth.Report for correction
17. What is the term for a substance that triggers an immune response and can induce the production of antibodies?
Answer: Antigen
Explanation: An antigen is a substance that triggers an immune response and can induce the production of antibodies.Report for correction
18. Which immune cells are responsible for producing antibodies in response to an infection?
Answer: B cells
Explanation: B cells are immune cells that produce antibodies in response to an infection, making them a key part of the adaptive immune response.Report for correction
19. Which of the following is an example of an immunosuppressive drug used to reduce the immune response?
Answer: Steroid
Explanation: Steroids are immunosuppressive drugs used to reduce the immune response and are often prescribed in certain medical conditions.Report for correction
20. What is the term for a group of proteins that help regulate immune responses and promote inflammation?
Answer: Cytokines
Explanation: Cytokines are a group of proteins that help regulate immune responses and can promote inflammation when necessary.Report for correction
21. Which of the following is a type of white blood cell that plays a role in allergic reactions and parasitic infections?
Answer: Eosinophils
Explanation: Eosinophils are white blood cells that play a role in allergic reactions and the immune response to parasitic infections.Report for correction
22. What is the term for a state of weakened or impaired immune function?
Answer: Immunodeficiency
Explanation: Immunodeficiency refers to a state of weakened or impaired immune function, which can make individuals more susceptible to infections.Report for correction
23. Which of the following is an example of a viral disease that affects the immune system and can lead to acquired immunodeficiency?
Answer: HIV/AIDS
Explanation: HIV (Human Immunodeficiency Virus) is a viral disease that affects the immune system and can lead to acquired immunodeficiency syndrome (AIDS).Report for correction
24. What is the term for the process by which immune cells "remember" previous infections and respond more effectively upon re-exposure to the same pathogen?
Answer: Memory response
Explanation: The memory response is the process by which immune cells "remember" previous infections and respond more effectively upon re-exposure to the same pathogen.Report for correction
25. Which immune cells are responsible for regulating and suppressing immune responses to prevent excessive inflammation and autoimmunity?
Answer: Regulatory T cells
Explanation: Regulatory T cells (Tregs) are immune cells that play a role in regulating and suppressing immune responses to prevent excessive inflammation and autoimmunity.Report for correction
