Explanation:

The brain is protected by a strong rigid skull because brain is a sensitive organ of the body. Skin protects the body from drying out by regulation water balance and prevention of dehydration. Antibodies can neutralize viruses by blocking attachment to the host cell as well as preventing penetration of the host cell membrane. The rib cage provides protection for the heart and lungs. Both organs are very sensitive. Skin is responsible for the prevention of germs from entering the body. White blood cells engulf and digest bacteria to avoid infection. The spinal cord is encased and protected by the spine. Helper T cells help activate B cells to secrete antibodies and macrophages to destroy ingested microbes.
