Activity Questions 1. Which lymphatic organs have afferent lymphatic vessels? 2. How do lymphocytes enter: a. lymph nodes b. MALT (e.g. tonsil)
Question 22 1 pts How do naïve and mature lymphocytes differ? Mature lymphocytes cannot bind to antigens Naive lymphocytes can differentiate to become either B or T cells; Mature lymphocytes are cells that have made that decision and cannot switch back. O Mature lymphocytes have not encountered an antigen before Nalve lymphocytes have not encountered an antigen before Naive lymphocytes cannot bind to antigens
