It includes physical barriers like the skin and mucous membranes, chemical defenses such as stomach acid, and immune cells like macrophages and natural killer cells that attack invaders non-specifically. This type of immunity is <strong>present at birth<\/strong> and provides <strong>rapid, general protection<\/strong> against a wide range of pathogens but does not have memory.<\/p>\n\n\n\n<p>In contrast, <strong>acquired (adaptive) immunity<\/strong> develops over time as the body is exposed to different pathogens or receives vaccinations. It involves specialized immune cells such as <strong>B cells and T cells<\/strong>, which recognize specific antigens and produce a targeted immune response. Acquired immunity is <strong>slower to respond initially<\/strong>, but it has <strong>memory<\/strong>, meaning it can recognize and react more effectively to previously encountered pathogens in the future.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>One Reason the Immune System Can Be Negatively Impacted<\/strong><\/p>\n\n\n\n<p>One major factor that can weaken a person\u2019s immune system is <strong>chronic stress<\/strong>. Stress leads to the continuous release of the hormone <strong>cortisol<\/strong>, which suppresses the immune response by reducing the effectiveness of white blood cells. This makes the body more vulnerable to infections, slows down recovery, and increases the risk of diseases.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>How Vaccines Teach the Immune System<\/strong><\/p>\n\n\n\n<p>Vaccines help train the immune system by introducing a <strong>weakened, inactive, or part of a pathogen<\/strong> (such as a protein or toxin). This stimulates the immune system to produce <strong>antibodies and memory cells<\/strong> without causing the disease. If the real pathogen enters the body later, the immune system recognizes it quickly and mounts a faster, stronger defense. This is how vaccines provide long-term protection against infectious diseases.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Describe the difference between innate and acquired immunity.
