Blood and lymph these are the two circulating fluids
Other liquids circulating in the body include interstitial fluid, which surrounds cells and tissues; lymph, which flows in the lymphatic system and helps transport immune cells; and cerebrospinal fluid, which surrounds the brain and spinal cord providing protection and nutrients.
Fluids and particles absorbed into lymph capillaries are called lymph.
Interstitial fluid
The aged red cells self destruct in the spleen , where they squeeze through the red pulp of the spleen. When the spleen is removed, the number of abnormal red cells and old cells circulating in the blood increases considerably.
Lymph nodes can produce and contain lymph fluid, but they do not typically leak fluid. If a lymph node is damaged or infected, it may become enlarged or tender, but leakage of lymphatic fluid from a lymph node is not a common occurrence.
Fluid and particles absorbed into lymph capillaries
lymph capillary Lymph fluid is filtered in lymph nodes. Lymph nodes are along lymph vessels which that run along blood vessels. Lymph vessels draw in interstitial fluid (fluid between cells) and it them becomes lymph fluid. Lymph nodules are in connective tissue in place of high traffic and does not function as a filter because it's not along a lymph vessel.
Lymph
Lymph is a clear fluid
when lymph fluid is contained inside lymph vessels or lymph node(lymphatic system) it is called lymph whereas when it is squeezed out of cells b/w the cell membranes it is called tissue fluid
The lymph capillary in the right arm channels excess fluid from plasma. This fluid flows in the direction of the lymph nodes in the axilla through larger lymphatic vessels where the fluid becomes lymph.
