Has valves to help transport fluid

Isolated to just a few places in the body

Interacts with the cardiovascular system

Is primarily a transport system of tubes and nodes (choose only one system)

Explanation / Answer

1: Transport blood- Neither. Circulatory system transports blood. Lymphatic system drains fluids and returns plasma and proteins back to the circulation. Immune system transports T-cells and b-cells.

2: Is primarily a system of cells, tissues and organs that protects the body from pathogens- true of a healthy lymphatic system. Lymphatic system is a collection of lymph vessels, structures and organs such as spleen, tonsils, thymus and adenoids are part of it.

3: Has valves to transport fluid- true for a healthy lymphatic systems. Lymphatic capillaries are anchored to the tissues by protein filaments that regulate lymph flow from tissues. When pressure in the tissue is high the valves open and lymph is taken up into the vessel.

4: Isolated to just few places in the body- neither. Both lymphatic system and immune system spread across the whole body.

5: Interacts with the cardiovascular system- true for a healthy lymphatic system. Lymphatic system is associated with cardiovascular system while immune system is associated with nervous and endocrine system.

6: Is primarily a transport system of tubes and nodes- true for a healthy lymphatic system. Immune system is primarily composed of T-cells and B-cells while Lymphatic system comprises lymph nodes and lymph vessels(tubes) and other related organs.
