Chapter 27.1, Problem 2MQ
Summary Introduction
Immunity is the ability of a host organism to resist infection and diseases. All the cells, organs and tissues involved in generating immunity comprise the immune system. There are two prime types of immune system: adaptive and innate. The adaptive immune system is a more advanced system and consists of lymphocytes both “B and T cells”. These T and B cells are formed at the bone marrow but the maturation of T cells take place in the thymus. To ensure the availability of healthy T cells two different types of selection takes place, that is positive selection and negative selection.
