CD4 cells are infection-fighting white blood cells.
<h3>What are CD4 cells?</h3>
White blood cells called CD4 cells also referred to as T cells, are crucial components of your immune system because they combat infection. When a person has HIV, their CD4 count is used to determine how well their immune system is functioning (human immunodeficiency virus).
HIV not only attacks CD4 cells but also makes use of them to spread the infection. HIV uses the CD4 cells' capacity for viral replication to kill CD4 cells by producing more of the virus. The CD4 cells ultimately enlarge and explode as a result of this. HIV weakens the immune system by destroying CD4 cells.

Answer: It is no longer circulated throughout the body supplying oxygenated blood. The un-oxygenated blood turns blue which makes the body look “dusky”.

(If the person was laying on their back, the blood would pool on the backside of the body)
Explanation:
When a person dies, the heart stops circulating blood and the lungs stop oxygenating the recirculated blood. The blood turns blue and pools in lowest place.
