Lymphatic & Immune Systems
For this modules case assignment, please prepare a 2-3 page paper in which you: 1. Provide an overview of the lymphatic system. 2. Explain the function of the following organs of the lymphatic system: -red bone marrow -thymus gland -spleen -lymph nodes EXPECTATIONS Page Length: 2 to 3 pages Format TUI encourages all students to comply with APA style and format guidelines for proper citation of references. For more information see Syllabus Home Page, APA Style and Format. Scholarly Content Your SLP and your case assignments are considered scholarly works. Your final work should include a MINIMUM of 10 peer reviewed (scholarly) sources. This does not mean that you must place 10 peer reviewed sources in each module of your Case/SLP. I anticipate that the nature of the questions which must be answered in this project will result in the accumulation of more than 10 references, but 10 is the minimum number. This means by the end of module 5, I should be able to go back and count AT A MINIMUM a total of 10 scholarly-peer reviewed publications in all of your submitted papers. If you are uncertain what a peer reviewed (scholarly) source is, please click this link Please keep in mind that you should not use sources such as “Answers.com” or “Wikipedia” or “Wikianswers”. None of these are scholarly sources and they can be “modified” by any registered user which makes it unreliable. It could very well be that those who modify subjects in Wikipedia have a very good knowledge of the subject, however, since we have no way of knowing their credentials or intentions, we cannot guarantee that the source is reliable. It is a good place to start, but should not be used as factual in graduate writing. For graduate study, be sure to stick to peer reviewed journals and scientific sources.

Your paper should make use of appropriate headings and subheadings. You should not cut & paste the questions posed and answer them like a “Question and Answer” session. Your finished paper should read like an academic paper.

The Lymphatic and Immune System
Overview
The lymphatic system a critical component of the immune system and comprises a transport system that functions together with the circulatory system. Its main function involves relaying surplus interstitial fluid from the interstitial space back into circulatory blood through the thoracic duct. Together with the surplus interstitial fluid, surplus proteins and wastes are relayed back to the circulation. The system also functions as a medium for immune cells and facilitates immune reaction. The systemic lymph nodes sieve the interstitial flow thereby breaking down viruses, bacteria and other wastes (Margaris & Black, 2012). The lymphatic system constitutes a secondary circulatory network of extremely fine vessels as well as tubes referred to as lymphatics which drain lymph from the entire body. Lymph is made up of water, protein elements, salts, urea, glucose, lymphocytes (B and T-cells) and other elements. Lymphatics are exhibited all over the body except in the central nervous system. This lymphatic system constitutes majorly the red bone marrow, spleen, lymph nodes, thymus gland and the tonsils. (Szuba et al, 2003).
* The red bone marrow
The red bone marrow is a soft, spongy tissue located in the central cavities of axial as well as long bones. It constitutes hematopoietic tissues and adipose cells contained in vascular sinuses intermingled in a meshwork of trabecular bone. It is the major organ for blood cell production such as neutrophils, basophils, eosinophils, and lymphocytes. The lymphocytes differentiate into B- and T-cells. It is also the site for B-cell maturation while T-cells mature in the thymus (Travlos, 2006).
* The thymus gland
The thymus constitutes a site for T-cell production active. The thymus is bilobed with each lobe divided into other lobules via connective tissue septa. It has a parenchyma organized into cortical and medullary elements. Each lobule has an immense concentration of i...
