Answer:
The skeletal system provides the shape and form for our bodies in addition to supporting and protecting our bodies, allowing bodily movement, producing blood cells, and storing minerals. This system consists of bones, cartilage, and joints.
The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. It consists of the nose, larynx, trachea, diaphragm, bronchi, and lungs.

<span>Air pollution has a variety of effects upon health, including biochemical, physiological and breathing difficulties (such as increased coughing, increased C02 intake, restricting air flow, disrupt ventilation etc). The statement "It could restrict air flow through the bronchi" doesn't explain the effect of air pollution effectively enough.</span>
