Answer 16

wait wait wait @kyrea is right
because...
The immune system of our body is our body's defense system. It protects us from foreign particles that enter our body. It could be divided into two categories: nonspecific defenses and specific defenses. The nonspecific defenses include:
the skin, which is somewhat remove foreign invaders impermeable and acts as a physical barrier
the mucous membranes, which act to trap and
cilia, which line the respiratory tract and sweep away foreign materials that are inhaled
the acid in the stomach, which destroys microorganisms that are ingested
the circulatory white blood cells, which engulf and destroy foreign invaders that enter into the blood
The interferons, which are produced by cells that have been infected with a virus and carry a signal to adjacent cells, thereby protecting them from the infecting virus.
