Another type of lymphoid organ are lymph nodes, which are tightly packed balls of lymphoid cells and protein.

In babies the leading edge is most often caused by lymphoid hyperplasia, or the enlargement of lymphoid tissue.

Now, B-cell development begins in the bone marrow, which is a primary lymphoid organ.

The most common type is marginal zone lymphoma of mucosa-associated lymphoid tissue or MALT.

Humans have hundreds of lymph nodes, scattered throughout the body, and they're considered secondary lymphoid organs.

人有很多淋巴结，分散在身体的各个部位；他们（淋巴结）被认为是次级淋巴器官。

Some become myeloid progenitor cells whereas others become lymphoid progenitor cells.

一些会成为髓系祖细胞，而其它的会成为淋巴系祖细胞。

Now the final type of lymphoid cell is the T cell and it's in charge of cell mediated immunity.

最后一种淋巴细胞就是T细胞啦，它负责细胞介导免疫。

A final set of lymphoid organs worth mentioning are the tonsils, which include the adenoid, tubal tonsils, palatine tonsils, and lingual tonsils.

最后值得一提的淋巴器官是扁桃体，包括腺样体（咽扁桃体）、咽鼓管扁桃体、腭扁桃体和舌扁桃体。

Another lymphoid organ is the thymus, which is in the upper part of the chest - just below where a necklace might sit.

另一个免疫器官是胸腺，它位于胸的上部，刚好低于佩戴项链的位置。

These X4 strains kind of lay low in the lymphoid tissues, and steadily destroy of CD4 T cells, since about 90% of T cells are found in lymphoid tissue.

这些X4嗜性毒株在淋巴组织中十分低调，逐步摧毁CD4-T细胞，因为大约90%的T细胞都分布于淋巴组织中。

Lymphoid organs remove foreign material from the lymph to keep it from entering the bloodstream, and act as lookout points for the body's immune defenses.

淋巴器官从淋巴中移除异体物质，阻止它们进入血流，也发挥免疫防御岗哨的作用。

另一个淋巴器官是脾，大约拳头大小，位于身体左侧，膈肌下方、胃的上方。

B cells and NK cells complete their development where they started - in the bone marrow, whereas some lymphoid progenitor cells migrate to the thymus where they develop into T cells.

B细胞和NK细胞在它们产生的地方（骨髓中）完成发育，而一些淋巴系组细胞会迁移到胸腺，在那里它们发育成为T细胞。

Some lymphoid organs are in the form of diffuse lymphoid tissue, where they are just a loose arrangement of lymphoid cells and protein, this is typical in the lining of the gastrointestinal and respiratory tract.

一些淋巴器官以弥散淋巴组织的形式存在，它们只是由淋巴细胞和蛋白质松散排列而成，这在胃肠道和呼吸道的内层很典型。
