A communicable disease is one that is spread from one person to another through a variety of ways that include: contact with blood and bodily fluids; breathing in an airborne virus; or by being bitten by an insect.
2. The Immune System—The Body's Defense Against Infection. Vaccines prevent diseases that can be dangerous, or even deadly. Vaccines greatly reduce the risk of infection by working with the body's natural defenses to safely develop immunity to disease.
3. The primary function of teeth is mastication: cutting, mixing, and grinding ingested food to allow the tongue and oropharynx to shape it into a bolus that can be swallowed. The teeth are generally conceptualized as a U-shape, with the bottom of the U representing the front teeth.
4. The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.
8. Keeping your body clean helps prevent illness and infection from bacteria or viruses. Like in our example, the simple act of washing your hands regularly is an effective way to keep germs from spreading.
