Verified step by step guidance
1
Understand the primary functions of the lymphatic system. It is part of the circulatory system and the immune system, primarily responsible for transporting lymph, a fluid containing infection-fighting white blood cells.
Recognize that the lymphatic system does not produce red blood cells. Red blood cells are produced in the bone marrow, which is part of the skeletal system.
Identify that the lymphatic system is not responsible for transporting oxygen to tissues. This function is carried out by the cardiovascular system, specifically through red blood cells in the blood.
Clarify that the lymphatic system is not a closed circulatory system. Unlike the cardiovascular system, the lymphatic system is open-ended, allowing lymph to flow through lymphatic vessels and nodes.
Learn that one of the key roles of the lymphatic system is to help in the absorption of dietary fats. This occurs in the small intestine where lymphatic vessels called lacteals absorb fats and transport them to the bloodstream.
