Answer 2

ANSWER:

Lymphocytes develop in the thymus and bone marrow (yellow), which are therefore called central (or primary) lymphoid organs. The newly formed lymphocytes migrate from these primary organs to peripheral (or secondary) lymphoid organs.

The two primary types of lymphocytes are B lymphocytes and T lymphocytes, or B cells and T cells. Both originate from stem cells in the bone marrow and are initially similar in appearance. Some lymphocytes migrate to the thymus, where they mature into T cells; others remain in the bone marrow, where—in humans—they develop into B cells. Most lymphocytes are short-lived, with an average life span of a week to a few months, but a few live for years, providing a pool of long-lived T and B cells. These cells account for immunologic “memory,” a more rapid, vigorous response to a second encounter with the same antigen.
