Lymph is mainly leakage from blood vessels, thus it is almost identical EXCEPT for the absence of Red Blood cells.
The lymphatic system is often referred to as a secondary circulatory system as it consists of a network ofvessels that assist the blood in returningfluid from the tissues back to the hert. In this way, the lymphatic system is a complementary system for the circulatory system. After draining the tissues of excess fluid, the lymphatic system returns this fluid to the cardiovascular system. This helps to maintain blood volume, blood pressure and prevent oedema. Hematoma
Yes, pigs have lymph nodes.
i shouldn't think so, it can be a sign of infection.
No. Reptiles do not have lymph nodes as mammals do. Reptiles have lymph tissue in certain organs, particularly the spleen, but no peripheral nodes. They do have valves along the lymph perivascular areas though, sometimes called lymph "hearts", but these are not directly comparable to lymph nodes for trapping of toxins.Source: Infectious Diseases and Pathology of Reptiles By Elliott R. Jacobson"Although reptiles lack discreet lymph nodes, they do have less structured lymphoid cell aggregates within intestinal and pharyngeal mucosa."Source: Investigative Immunotoxicology By Helen Tryphonas
Fluids and particles absorbed into lymph capillaries are called lymph.
Interstitial fluid
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.
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
Lymph
Lymph is a clear fluid
Lymph Vessels return intercellular fluid to the veins.

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.
The orgin on lymph is this: the cardiovascular system pumps blood through its system but it cannot return all the fluid from the body cells. The lymph system picks up 60%of the fluid dropped off at the cellular level, at this point we are talking about interstial fluid, the IF picks up plasma and becomes tissue fluid. The tissue fluid is then picked up my lymph capillaries, the tissue fluid is now called lymph.
The lymph nodes certainly could leak fluid. This happens quite frequently if the lymph nodes are infected and go untreated.
