Summary Introduction
Introduction:
The body contains a well-defined system to protect itself from infections and harmful agents. This system is known as the immune system. Any infection or injury generates a response in the body. The immune system has the ability to store and retrieve the responses about past pathogens and infections. The immune system generates three types of response to destroy the invading pathogens. These three immune responses are “innate response; primary response and the secondary response”.

Immediate and Passivearrow_forwardWhich of the following is not part of the innate immune system? a. Antibodies b. Skin c. Enzymes d. Neutrophilsarrow_forwardAntibodies against a specific antigen can be injected into a person to provide passive immunity. For which reason is this NOT as effective as the process of vaccination with that antigen? Select one: a. Injection of antibodies may cause allergic reactions, while vaccination never causes allergic reactions. b. Injection of antibodies does not provide long-lasting immunity, and vaccination with antigens triggers a clonal selection of B cells and cytotoxic T cells. c. Vaccination with antigens triggers a clonal selection of B cells and cytotoxic T cells. d. Injection of antibodies does not provide long-lasting immunity. e. Injection of antibodies does not provide long-lasting immunity and may cause allergic reactions, while vaccination never causes allergic reactions.arrow_forward
- Vaccines are given to provide protection against pathogen causing infections. Which of the following statements best describes how vaccines work? a Fever and swelling develop which is the first response in killing a pathogen b. Antibodies in the vaccine provide the body with nonspecific immunity to an antigen. c. An inactivated or killed virus stimulates the body to develop specific immunity to that type of virus. d. Heathy bacteria causes the body to release toxins which will protect the body if later exposed to different type of bacteria.arrow_forwardThe adaptive (specific) defense system: a. is the body's first line of defense against invading pathogens b. is an innate defense c. issues an attack specific to particular foreign substances d. includes the skin and mucous membranesarrow_forwardAn essential property of the immune system is self-regulation. An immune response that is not adequate can lead to immunodeficiency, whereas an immune response that is excessive can lead to conditions from allergic responses to autoimmune diseases. Which of these is not an example of a breakdown of the self-regulation of the immune system?a. Multiple sclerosisb. Huntington diseasec. Systemic lupusd. Fibromylagiaarrow_forward
- Concerning the adaptive immunity, which of the following statements is CORRECT: a. The adaptive immune response occurs very rapidly b. The adaptive immune response leads to us remembering antigens c. The adaptive immune response occurs mainly in the thymus d. The adaptive immune response is mostly dependent on antibodies e. The adaptive immune response is mostly dependent on the complement cascade 46) Concerning acute inflammation, which of the following statements is INCORRECT: a. localised redness occurs because of hyperaemia b. localised heat occurs because of increased bloodflow c. Release of bradykinins and other inflammatory mediators causes localised paind. swelling occurs because capillary permeability is reduced, preventing plasma recirculatione. Inflammatory chemicals at the site of inflammation act as chemotactic agentsarrow_forwardDecreased immunity is a symptom of HIV/AIDS. This is caused by which of the following? Select one: a. HIV destroys antigens. This decreases the possibility of recognizing pathogens in the future. b. HIV destroys memory T cells. If the body is infected again, there is no antibodies to fight an infection. c. HIV attacks the macrophages. Pathogens cannot be destroyed once they enter the body. d. HIV attacks the helper T cells. This allows pathogen cells to enter the body unnoticed.arrow_forwardExplain why each choice (a-d) is correct or incorrect. A vaccine is effective because a. The vaccine contains the antibodies necessary to fight infection. b. The vaccine contains the lymphocytes necessary to fight infection. c. The secondary response of the adaptive immunity is faster and more efficient than the primary response. d. B lymphocytes are unable to mount an immune response the first time they are exposed to a new pathogen.arrow_forward
