The colorless liquid produced as a byproduct when plasma passes nourishment to capillaries and cells is known as Lymph.

The extra fluid that leaks out of cells and tissues but is not reabsorbed into capillaries is what is referred to as lymph, also known as lymphatic fluid. Since RBCs are missing in lymph, lymph is colourless, the colour of blood is caused by the presence of haemoglobin in RBCs.

They can be discovered in a number of locations on the body, including as the groyne, armpits, chest, abdomen, and throat. They typically exist in chains or groupings. All are located close to veins and arteries and are embedded in fatty tissue. Although lymph nodes serve a variety of purposes, body defence is typically one of them.
