Lymph
(Science: physiology) The almost colourless fluid that bathes body tissues and is found in the lymphatic vessels that drain the tissues of the fluid that filters across the blood vessel walls from blood.
lymph
the blood plasma and white blood corpuscles that have passed from the cirucuatory vessels and that surround tissues and cells

The lymphatic system is composed of lymph vessels, lymph nodes, and organs.

Definition of lymphopenia :
A decrease in the number of lymphocytes (a variety of white blood cells) in the blood, which may occur in a wide variety of diseases.
Small bean-shaped structures scattered along the vessels of the lymphatic system. The lymph nodes produce white blood cells and filter bacteria and cancer cells that may travel through the system.

LYMPH SYSTEM - CLEANING UP THE FLUIDS
We have already discussed the circulatory system that has your blood and transports nutrients, dissolved gases, and waste products through your body.
Lymphocyte
A lymphocyte is a type of white blood cell that is part of the immune system. There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins.
How Lymphocytes Produce Antibody
The scanning electron micrograph (right) shows a human macrophage (gray) approaching a chain of Streptococcus pyogenes (yellow). Riding atop the macrophage is a spherical lymphocyte.

The Lymphatic System
The respiratory system
(7) The respiratory system functions in the exchange of the gases, oxygen and carbon dioxide.
Cytotoxic lymphocyte production follows the rise of HIV in the blood.
HIV specific CD4+ T cells may be especially susceptible to attack and destruction by HIV. HIV binds to CD-SIGN, a glycoprotein expressed on dendritic cells.
Cytotoxic T lymphocytes T cells that trigger cell death by apoptosis in cells that display foreign antigens on class I MHC proteins. Also called killer T cells.
Allorecognition: Recognition by T cells of the MHC molecules on an allogeneic individual's antigen-presenting cells, which results in allograft rejection in vivo and mixed lymphocyte reaction (MLR) in vitro.
When we talk about lymphocytes, we can separate them into the B-lymphocyte, that makes the antibodies, and the T-lymphocyte, that can then be separated into two different subsets, one that we call CD-4 and one we call CD-8.
An immunoglobulin protein produced by B- lymphocytes of the immune system that binds to a specific antigen molecule. (See monoclonal antibodies, polyclonal antibodies.) Anticodon.
DNA was obtained from blood lymphocytes from a male donor. The library was prepared in four distinct sections designated as RPCI1, RPCI3, RPCI4 and RPCI5, respectively, each having 120 kbp average inserts.
The primary hosts for HIV are the white blood cells variously called helper T lymphocytes, helper T cells, or CD4+ T cells.
HIV infects a number of cell types including T-lymphocytes, macrophages, dendritic cells and neurons. AIDS occurs when lymphocytes, particularly CD4+ T cells are killed off, leaving the patient unable to fight off opportunistic infections.
It is also hypothesized that components of semen, such as the spermatozoa as well as the seminal plasma, can cause immunosuppression in the body when introduced to the bloodstream or lymph.
The genes that code for these antibodies differ from one lymphocyte to the next because when the lymphocytes are produced, different regions of the DNA are deleted so that each lymphocyte has a somewhat different version of the genes involved.
Cancer of the developing blood cells in the bone marrow. Leukemia leads to rampant overproduction of white blood cells (leukocytes); symptoms usually include anaemia, fever, enlarged liver, spleen, and/or lymph nodes. [Talking Glossary]
