Lymph found only when there is a pathological condition that allows it to leak from capillaries ____.
LenKa [72]

Answer:  All of the choices are correct.

Explanation:

Schamberg's disease is the pathological condition that allows lymph to leak from the blood capillaries, it causes no other symptoms beside skin discoloration and itching. The condition is caused by inflammation of capillaries near the surface of skin and subsequent leaking of blood cells into surrounding tissues.

So, the Lymph  found in this patholgical condition is a fluid that circulates the entire body in the lymphatic system. The lymphoid organs include (the spleen, lymph nodes, bone marrow, thymus and lymph tissue) . These lymph nodes are small, bean-shaped structures which produce and store cells, specialized in fighting infections.

In the spleen (an organ in the upper left abdomen, filtration of  these blood and disposal of worn-out blood cells occurs ), Hence, provides a reserve supply of blood.

However, Fluid in the spaces between the tissues are called interstitial fluid (tissue fluid). They provides the cells of the body with nutrients (via the blood supply) and a means of waste removal.

As such, Lymph is formed when the interstitial fluid is collected through tiny lymph capillaries, which are located throughout the body. It is then transported through lymph vessels to lymph nodes, which clean and filter it. Lymph then flows on to the lymphatic ducts, before emptying into the right or the left subclavian vein, where it mixes back with blood.
