Answer:
The body system described in the image is the nervous system, which is primarily responsible for coordinating body functions using electrical messages.
Explanation:
The nervous system is connected by nerves to each and every structure and organ, in order to control their functions. This occurs because of the connection between the central (CNS) and peripheral nervous systems.
The neuron is the functional base of the nervous system, and is responsible for the transmission of information in the form of electrical signals, called nerve impulses.
The transmission of nerve impulses occurs through the joint action of receptors, nerves, integration centers and effectors.The information that goes from the periphery to the CNS goes by afferent pathway, while from the CNS to the periphery it travels by efferent pathway.
The other options are not correct because:
- <em>Protecting and defending the body against germs that have entered the body is function of Immune system</em>
- <em>

HIV<span> (</span>human immunodeficiency virus<span>) is a virus that attacks the immune system, the body's natural defense system. Without a strong immune system, the body has trouble fighting off disease. Both the virus and the infection it causes are called </span>HIV<span>. White blood cells are an important part of the immune system.
and also
</span>The virus can be transmitted through contact with infected blood, semen, or vaginal fluids.Within a few weeks of HIV infection, flu-like symptoms such as fever, sore throat, and fatigue can occur. Then the disease is usually asymptomatic until it progresses to AIDS. AIDS symptoms include weight loss, fever or night sweats, fatigue, and recurrent infections.No cure exists for AIDS, but strict adherence to anti-retroviral regimens (ARVs) can dramatically slow the disease's progress as well as prevent secondary infections and complications.
Answer:
