Which of the following is a function of the lymphatic system? Check all that apply 1) Recover fluid from the interstium to the b
nikitadnepr [17]

1 & 2

The lymph system acts like blood vessels only that instead of blood, they carry lymph. Just like certain organs as associated with the circulatory system like heart, the lymph system has such organs like the spleen and thymus.

Explanation:

When blood passes through capillaries, the blood pressure causes the blood plasma to filter through the capillary walls. This fluid then gets into the extracellular spaces of the cells and tissues and nourishes the cells. This fluid in which the cells ‘bath’ in is called interstitial fluid.  Excess interstitial fluid flows back through the lymphatic systems and back to the blood through the subclavian veins of the thoracic duct.

The lymph system has several functions. It is responsible for the removal of foreign material like bacteria because the lymph nodes have 'meshwork' that ‘sieves’ the lymph fluid and immune cells destroy bacteria and viruses.
