I think A would be the correct answer. Your skin does not produce white blood cells, your body produces white blood cells and releases them into your blood system. Your skin does not also make T cells or antibodies. This all happens internally and they stay internal. Your body can absorb things like histamine, however I’m not sure how this would help to keep pathogens out of the body.
And? What do you want me to do abt it?
The answer is under the question..hopefully that helps you :) !
Answer:
A and D
Explanation:
A. Sleep deprivation in turn downregulates dopamine receptors, which makes people more impulsive and vulnerable to drug taking.
D. When a person repeatedly uses drugs, he or she increases the risk for insomnia. This is because continued substance abuse affects the neurochemical functioning of the brain. It disrupts the brain’s sleep-regulatory systems and, in turn, disturbs the latency, duration, and quality of sleep for the user.
The physical barrier of the immune system is your body tissue and skin.
