harmful particles would get into your bloodstream
B

Explanation: 

Detailed explanation-1: -The lymphatic system clears away infection and keeps your body fluids in balance. If it’s not working properly, fluid builds in your tissues and causes swelling, called lymphedema.

Detailed explanation-2: -Returning lymph to the bloodstream helps to maintain normal blood volume and pressure. It also prevents the excess buildup of fluid around the tissues (called edema).

Detailed explanation-3: -When the lymph nodes are fighting the infection, they often swell and become sore to touch. Sometimes cancer cells spread from where a cancer started (the primary site) to other parts of the body. They can travel around the body in the blood or through lymph fluid.

Detailed explanation-4: -If infection is the cause of your swollen lymph nodes and isn’t treated, an abscess may form. Abscesses are localized collections of pus caused by infections. Pus contains fluid, white blood cells, dead tissue, and bacteria or other invaders. An abscess may require drainage and antibiotic treatment.
