Solution

Lymph is a fluid which flows through the lymphatic system of the body and takes part in transportation. Lymph is formed by the seepage of blood plasma, proteins and few blood cells through the pores of capillaries.

Lymph transports protein, fats and other nutrients from the digestive system. Lymph also collects bacteria and other pathogens from the bloodstream and brings to the lymph nodes to destroy them. Lymph mainly contains blood plasma with some white blood cells.

The main difference between blood and lymph is blood contains RBCs (Red Blood Cells) which gives red colour whereas lymph does not carry RBCs. Thus lymph is pale yellow in colour.
