The document outlines the characteristics of adaptive immunity, highlighting its tailored responses to specific pathogens, the activation and proliferation of immune cells, and the formation of immunological memory. It details the two main types of lymphocytes involved in adaptive immunity, their development, and the two basic types of immune responses. Additionally, it describes the components of the lymphatic system and associated lymphoid organs crucial for specific immunity.

1. Please answer all questions.
1) Adaptive immunity has five distinct attributes: a) ___ : Adaptive immune responses are
precisely tailored reactions against specific attackers. b) : Cells of adaptive immunity activate
only in response to specific pathogens. c) : Once induced, cells of adaptive immunity proliferate
to form many generations of nearly identical cells called clones. d) : As a rule, adaptive
immunity does not act against normal body cells. e) : An adaptive immune response has
immunological memory and is able to generate faster and more effective responses in subsequent
encounters with a particular pathogen or toxin. 2) These characteristics of adaptive immunity
involve the activities of which are a type of leukocyte (white blood cell) that acts against specific
pathogens. 3) Human lymphocytes of humans form in the where blood stem cells produce all
types of blood cells. 4) There are two main types of lymphocytes, and a) arise and mature in the
red bone marrow of adults. b) begin in the bone marrow but mature in the thymus. 5) Adaptive
immunity consists of two basic types of responses, a) immune responses and often act against
intracellular pathogens. b) immune responses and often act against extracellular pathogens and
toxins 6) The long-term ability of descendants of B and T cells to mount adaptive immunological
responses against specific pathogens is called immunological 7) An is a protein secreted by the
descendant of a B cell that recognizes and strongly binds to the specific biochemical shape.
ELEMENTS OF ADAPTIVE IMMUNITY 1) The is composed of lymphatic vessels, which
conduct the flow of lymph, and lymphoid and that are directly involved in specific immunity. 2)
The lymphoid organs include nodes, the , the the and (MALT).
