• lymph nodes
  • The presence of the lymphatic-like system we described in the human choroid thus provides an anatomical basis for antigen presentation in the posterior segment of the eye, as well as a pathway from the eye to the sentinel lymph nodes, similar to that described for the anterior uveal lymphatic vessels.

  • In cases of infection, the lymph nodes usually become swollen because the body "automatically" transfers back bacteria to the nodes where they need to be eliminated with the help of white blood cells. (cancercrackdown.org)
  • Many studies have confirmed that the lymphatic system that is not working properly becomes the main reason of spreading of cancer because cancer cells from a primary tumor can become trapped inside the lymph nodes or lymph vessels or they can even start spreading in opposition to lymph flow because it is congested which ultimately results in secondary tumors.

  • fluid
  • Our study 2 provided substantial ultrastructural and immunohistochemical evidence using lymphatic markers for the existence of early absorption lymphatic capillaries located on the external side of the fenestrated vessels of the choriocapillaris, an ideal juxtaposition for the recirculation of extracellular fluid, as well as being a strategic location for immunologic surveillance.
