The secondary lymphoid organs.
Introduction:
The lymphatic system is the section of the vascular system and is also considered to be a vital part of the immune system, which comprises the network of lymphatic vessels. These transport clear liquid, which is known as lymph and they carry toward the heart. The lymphatic system consists of different organs known as lymphoid organs and they can be segregated into primary and secondary lymphoid organs.
Explanation of Solution
Secondary lymphoid organs refer to the sites wherein the antigens make an entry into the body and come in contact with the heavy populations of lymphocytes. The examples include lymph nodes, spleen, and tonsils. The lymph nodes, in particular, are responsible for capturing the products from the lymphatic, while the spleen plays a considerable role in collecting the materials from the blood.
These organs are busy and known to be highly organized organs of the body wherein the cells communicate. However, some of these organs are less organized in terms of their structure as compared to the spleen and lymph nodes. The purpose of these organs remains the same. One of the vital organs is Peyer’s patches and these are tissues present in the intestinal walls, which inspect the intestinal contents.
Therefore, it can be concluded that the secondary lymphoid organs are the locations wherein the antigens enter thebody and communicate with the dense populations of lymphocytes.
