The immune system has specific mechanisms to protect human beings from pathogens. The primary components of an immune system include the bone marrow, the thymus, the spleen, the lymphatic system, antibodies, and white blood cells. The system has some particular chemicals, cells, and body parts that defend the body against infections (Ted-Ed, 2018). White blood cells are the most paramount because their main work is fighting diseases. The immune system is the principal safeguard of the body against diseases, illnesses, and infections.
According to the video, the extensive network comprises tissues, organs, and cells, which synchronize the defense mechanism of the body against toxins, viruses, and bacteria. The system can quickly pinpoint and destroy the disease-causing organisms when they enter the body before they can multiply and make a person sick. The white blood cells are the most prominent of the system’s numerous components (Ted-Ed, 2018). The primary responsibility of the white blood cells is to fight microbes that are regarded as foreign to the body. The white blood cells are part of the lymphatic system and are primarily manufactured in the bone marrow.
Organisms such as bacteria and viruses are dangerous for the reason that they could make something as minor as a cold or a small cut fatal because of the underlying infections (Ted-Ed, 2018). The system relies solely on the millions of white blood cells, which act as the army against diseases and infections. White blood cells or leukocytes originate from the bone marrow and migrate to the lymphatic system and the bloodstream to carry out their work. There are 4,000 to 11,000 leukocytes in every microliter of blood. Leucocytes act like security personnel or an army of the body and constantly screen the blood tissues against harmful foreign matter.
