The lymphatic system is used for Cleansing the cellular environment, Returning proteins and tissue fluids to the blood, Providing a pathway for the absorption of fats into the bloodstream and Defending the body against disease, this system consists of lymph (or interstitial fluid), lymph vessels, lymph nodes, lymph organs, Monocytes and lymphocytes pass from the bloodstream through the blood capillary walls into the spaces between the cells in the body. When they pass into this lymph or interstitial fluid that surrounds cells, they perform their protective functions. Monocytes change into macrophages, destroy pathogens, and collect debris from damaged cells, Once monocytes and lymphocytes pass into the lymphatic capillaries, the fluid is termed lymph or lymphatic fluid.
Open access to the scientific literature means the removal of barriers (including price barriers) from accessing scholarly work. There are two parallel roads towards open access: Open Access articles and self-archiving. Open Access articles are immediately, freely available on their Web site, a model mostly funded by charges paid by the author (usually through a research grant). The alternative for a researcher is self-archiving (i.e., to publish in a traditional journal, where only subscribers have immediate access, but to make the article available on their personal and/or institutional Web sites (including so-called repositories or archives)), which is a practice allowed by many scholarly journals.
Open Access raises practical and policy questions for scholars, publishers, funders, and policymakers alike, including what the return on investment is when paying an article processing fee to publish in an Open Access articles, or whether investments into institutional repositories should be made and whether self-archiving should be made mandatory, as contemplated by some funders.
