Question

5 multiple choice 1 point hiv enters the body and breaks down the respiratory system circulatory system immune system muscular system

Explanation:

HIV (Human Immunodeficiency Virus) specifically targets and attacks CD4+ T - cells, which are crucial components of the immune system. Over time, as the virus replicates and destroys these cells, the immune system becomes severely weakened. The respiratory system is mainly involved in gas exchange (taking in oxygen and expelling carbon dioxide), the circulatory system is for transporting blood (and substances in it like oxygen, nutrients, hormones etc.), and the muscular system is for movement and maintaining posture. None of these are the primary target of HIV in the way described in the question.

Answer:

immune system
