Blood is red in color whereas lymph is colorless.

Lymph lacks RBCs, which are present in blood. Some blood proteins are also absent in lymph.

In lymph, white blood cells are found in abundance.

The main difference between the blood flowing in the circulatory system and the lymph flowing in the lymph system is that blood is pressurized by the heart, while the lymph system is passive. There is no lymph pump like there is a blood pump i.e. the heart. Instead, fluids ooze into the lymph system and get pushed by normal body and muscle motion to the lymph nodes.

Lymph flows in lymph vessels where as blood flows in blood vessels. (Lymph does finally open into larger veins.)

Lymph is highly important in protecting the body. It also drains excess fluid from the extra cellular space back into blood.

Blood is important in transportation, clotting and also protecting the body.
