Answer:
1. The respiratory system allows us to breathe . They bring oxygen into our body and remove carbon dioxide from the body .
2. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
3. The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).
4. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
5. The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to be transmitted to the whole body

Explanation:
Elements have been classified into three categories namely; metals, non-metals and metalloids. This classification was done based on certain characteristics or properties possessed by each element. Some of the characteristics used are: lustre, malleability, conductivity, melting point, boiling point etc.
- Metals are very good conductors of heat and electricity whereas metalloids and nonmetals are not.
- Metals and metalloids shine when polished i.e. they are lustrous, whereas nonmetals don't
- Metals are malleable i.e. can be beaten into sheets.
Texture is not a property used to classify metals and metalloids.
