white blood cells. They are the most numerous of all leukocytes. They are the first responders to infections. When bacteria are found‚ neutrophils will surround the bacteria and kill it‚ often dying in the process. B. Monocytes- help with immune defense and rebuild damaged tissue. They also produce proteins for the body and antigens‚ which stimulate antibody production. C. Eosinophils- are white blood cells that protect the body by killing and swallowing bacteria. If the eosinophil

In this particular disease‚ when one thing goes wrong in your immune system‚ that is the part of the body which fights off viruses‚ bacteria‚ and germs‚ our immune system is not able to function properly.

person’s immune system is broken‚ allowing viral and bacterial contagions to attack as the HIV reproduces so rapidly. Since the immune system cannot ably fight off both exterior and interior infections‚ a person becomes severely and frequently unwell. The HIV sufferer can then be said to have AIDS. Ultimately any opportunistic diseases will cause that person to die. The disease gained the name “Acquired Immune Deficiency Syndrome” (AIDS) after a cellular deficiency of the human immune system was found

What is AIDS? Human immunodeficiency virus (HIV) is a lentivirus (slowly-replicating retrovirus) that causes acquired immunodeficiency syndrome (AIDS)‚ a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive (1). A virus is a piece of genetic material‚ RNA or DNA‚ surrounded by a protein coat. To replicate‚ a virus must infect a cell and direct its cellular machinery to produce new viruses. A virus cannot

Even though the government should not be able to choose whether or not a child gets vaccinated‚ child vaccines should be mandatory because it helps build the immune system at an early age and it protects the child from getting a more powerful version of a disease.
