1. Explain the role of the Lymphatic System i.e. “What does the Lymphatic system do for the body?”
- The lymphatic system contributes to homeostasis by draining interstitial fluid as well as providing the mechanisms for defense against disease. There are 2 kinds of defenses that our body has: Innate (nonspecific) immunity and Adaptive (specific) immunity. The lymphatic system governs the latter.

2. Explain (briefly) the function of the Lymphatic system i.e. “How does it work, what prevents back flow, where does lymph come from and how does it get into the system?”
-The lymphatic system consists of a fluid called lymph, vessels called lymphatic vessels that transport the lymph, a number of structures and organs containing lymphatic tissue, and red bone marrow, where stem cells develop into the various types of blood cells, including lymphocytes. The mechanism behind the prevention of back flow is that lymphatic capillaries are slightly larger in diameter than blood capillaries and have a unique one-way structure that permits interstitial fluid to flow into them but not out with the help of valves. Most components of blood plasma filter through blood capillary walls to form interstitial fluid. After interstitial fluid passes into lymphatic vessels, it is called lymph.

I need Definition(small sentence 1-8) + General Function for each of these.

Lymph
-Fluid confined in lymphatic vessels and flowing through the lymphatic system until it is returned to the blood.
-fxn: Remove bacteria and certain proteins from the tissues, transport fat from the small intestine, and supply mature lymphocytes to the blood.

Lymph Vessel
-A large vessel that collects lymph from lymphatic capillaries and converges with other lymphatic vessels to form the thoracic and right lymphatic ducts.
-fxn: Devoted to propulsion of the lymph from the lymph capillaries, which are mainly concerned with absorption of interstitial fluid from the tissues

Lymph Node
-An oval or bean-shaped structure located along lymphatic vessels.
-fxn: Are garrisons of B, T, and other immunity cells. They act as filters or traps for foreign particles and are important in the proper functioning of the immune system. They are packed tightly with the white blood cells called lymphocytes and macrophages.

Lymph Duct
-A great lymphatic vessel that empties lymph into one of the subclavian veins.
-fxn: The right lymphatic duct drains lymph from the right upper limb, right side of thorax and right halves of head and neck. The thoracic duct drains lymph into the circulatory system at the left brachiocephalic vein between the left subclavian and left internal jugular veins.

Afferent Lymph Vessel
-Lymph vessels that carry lymph to a lymph node.
-fxn: The afferent vessels contain valves that open toward the center of the node, directing the lymph inward.

Efferent Lymph Vessell
-Lymph vessels that carry lymph from a lymph node from where the lymph may travel to another lymph node, may be returned to a vein, or may travel to a larger lymph duct.
-fxn: They contain valves that open away from the center of the lymph node to convey lymph, antibodies secreted by plasma cells, and activated T cells out of the node.

Cysterna Chyli
-The dilated beginning of the thoracic duct.
-fxn: Acts as a cavity or reservoir, it receives lymph from the right and left lumbar trunks and from the intestinal trunk.

Spleen
-Large mass of lymphatic tissue between the fundus of the stomach and the diaphragm.
-fxn: It houses two different kinds of tissue called white pulp and red pulp.
Within the white pulp, B cells and T cells carry out immune functions, similar to lymph nodes, while spleen macrophages destroy blood-borne
pathogens by phagocytosis.
Within the red pulp, the spleen performs three functions related to blood cells: (1) removal by macrophages of ruptured, worn out, or defective blood cells and platelets; (2) storage of platelets, up to one-third of the body’s supply; and (3) production of blood cells (hemopoiesis) during fetal life.

Thymus
-A bilobed organ, located in the superior mediastinum posterior to the sternum and between the lungs.
-fxn: It is the site of T cell maturation.

Tonsils
-Five tonsils, aggregations of large lymphatic nodules embedded in the mucous membrane of the throat.
-fxn: Participate in immune responses against inhaled or ingested foreign substances

Lymphocytes
-A type of white blood cell that helps carry out cell-mediated and antibody-mediated immune responses; found in blood and in lymphatic tissues.
-fxn: Distinguishes between normal cells and infected cells or invasive pathogens.

B-Lymphocytes
-A lymphocyte that can develop into a clone of antibody-producing plasma cells or memory cells when properly stimulated by a specific antigen.
-fxn: Make antibodies against antigens, to perform the role of antigen-presenting cells (APCs), and to develop into memory B cells after activation by antigen interaction

T-Lymphocytes
-A lymphocyte that becomes mature in the thymus and can differentiate into a helper T cell or a cytotoxic T cell, both of which function in cell-mediated immunity.
-fxn: Plays a role in the cell-mediated immunity. Has different subsets: Helper (CD4 T cells) and Cytotoxic (CD8 T cells).

Tissue Fluid
-The portion of extracellular fluid that fills the microscopic spaces between the cells of tissues; the internal environment of the body. Also called insterstitial or intercellular fluid.
-fxn: Bathes body cells and is constantly renewed by the blood.


4. How do these parts inter-relate?
The lymphatic system carries out immune responses and consists of lymph, lymphatic vessels, and structures and organs that contain lymphatic tissue (specialized reticular tissue containing many lymphocytes). Furthermore, the lymphatic system drains interstitial fluid, transports dietary lipids, and protects against invasion through immune responses.

5. What major things could go wrong with this system?
There are many things that could go wrong with this system. One of the deadliest is Acquired immunodeficiency syndrome (AIDS). AIDS is a condition in which a person experiences a telltale assortment of infections due to the progressive destruction of immune system cells by the human immunodeficiency virus (HIV). AIDS represents the end stage of infection by HIV. A person who is infected with HIV may be symptom-free for many years, even while the virus is actively attacking the immune system. HIV mainly damages helper T cells. Over 10 billion viral copies may be produced each day. The viruses bud so rapidly from an infected cell’s plasma membrane that cell lysis eventually occurs.
Another example of a disease that may be acquired if things go wrong with the lymphatic system is Systemic lupus erythematosus. This is a chronic autoimmune, inflammatory disease that affects multiple body systems. Lupus is characterized by periods of active disease and remission; symptoms range from mild to life-threatening. Two immunological features of SLE are excessive activation of B cells and inappropriate production of autoantibodies against DNA (anti-DNA antibodies) and other components of cellular nuclei
