AIDS attacks what system in the body?

AIDS, which stands for Acquired Immunodeficiency Syndrome, specifically targets the immune system. The virus responsible, HIV (Human Immunodeficiency Virus), attacks and weakens the immune system by destroying CD4 T cells, which are crucial for the body’s ability to fight off infections and diseases. When the immune system is compromised, it becomes significantly more challenging for the body to defend itself against various pathogens, including viruses, bacteria, and even certain cancers.

The other systems listed do not directly relate to the primary effects of AIDS. The nervous system deals with the brain and nerve function, the cardiovascular system pertains to heart and blood vessel health, and the respiratory system is involved with breathing and gas exchange. While a weakened immune system can eventually lead to complications affecting these systems, the initial and foremost impact of AIDS is on the immune system.
