MORE INFO:

The cardiovascular and lymphatic are both integral parts of the circulatory system. The cardiovascular system basically moves blood throughout the body. While the lymphatic system is part of the circulatory system, comprising a network of conduits called lymphatic vessels. Rather than blood the lymph systems carries a clear fluid called lymph (from Latin lympha, meaning “water goddess”) unidirectionally towards the heart. The lymph system is not a closed system. The circulatory system processes an average of 20 liters of blood per day through capillary filtration which removes plasma while leaving the blood cells.
