Lymph vs Blood Blood is circulated through the body by blood
vessels and lymph is transported by lymphatic vessels. Lymphatic
system is a system of vessels, cells and organs. Vessels
originate blindly, and the structure is similar to a vein with
valves. The vessels transport fluid called lymph that is similar
in composition to extra cellular fluid. Lymphatic system also
consists of a number of organs and cells that are collectively
referred to as white blood cells. Lymph is a protein containing
fluid transported by lymphatic vessels. Lymphatic vessels
transport the lymph at a low pressure. Structurally and
functionally they are similar to a vein. Lymphatic vessels
eventually join with the veinous system. Primary lymphoid organs
are the organs involved in the development of cells of the
lymphatic system. Secondary lymphoid organs are the organs
involved in housing cells of the lymphatic system and immune
response. Cells of the lymphatic system include granulocytes and
agranulocytes. Granulocytes are the Neutro
