Question

Do the statements below refer to the innate or adaptive immune System? acts immediately upon infection found in all animals found only in vertebrates same whether or not the pathogen has been encountered before second exposure to a specific pathogen elicits a faster and stronger response "remembers" an invader after initial infection Are the following statements about the lymphatic system true or false? the two main functions of the lymphatic system are to (1) collect fluid from body tissues and rid it of microbes, and (2) return collected and "cleansed" lymph fluid to the blood lymphatic vessels return lymph to the blood by draining it into veins near the heart lymph organs include the bone marrow, thymus, and spleen lymph nodes are full of macrophages and lymphocytes Do the following statements refer to the humoral or cell-mediated or both branches of the adaptive immune system? is mediated by lymphocytes that reside in the lymphatic system employs cells that have thousands of antigen receptors sticking out of their cell surface relies on cells that originate in the bone marrow relies on cells that spend time maturing in the thymus cells in this branch secrete free-floating antibodies Look at Section 24.7 and Figures 24.7A 24.7B in your textbook and identify the following statements about clonal selection of B cells as true or false: the first time that a pathogen enters the body, it is recognized by an antigen receptors on all B cells binding of an antigen to receptors on a B cell causes that B cell to grow, divide, and differentiate into both plasma effector cells and into memory cells plasma effector cells secrete antibodies to deal with the current infection memory cells will respond to later infections by the same pathogen vaccinations stimulate production of both plasma effector cells and memory cells after vaccination against a specific pathogen (e.g. measles), memory cells can respond more quickly and strongly to a subsequent measles infection a subsequent measles infection will cause the memory cells to grow, divide, and differentiate into both new plasma effector cells and into new memory cells vaccination "educates" the adaptive immune system to

Explanation / Answer

33 ans-Innate immunity-first defense against invader, also referred to as immediate response immune system.

34 ans-Innate immune systems (also known as in-born immunity system) are found in all plants and animals.

35 ans-Adoptive immunity found only in all vertebrates.

36 ans-Innate Immunity-the same whether or not the pathogen has been encountered before, acts immedietly.

37 ans-Adoptive immunity is pathogen-specific receptors are "acquired" during the lifelong of the organism and  it prepares the body's immune system for future challenges/infection.

38 ans-Adaptive immune system ‘remembers’ the infection agent and can prevent it from causing disease later such as measles and diphtheria
