(a) Trachea, (b and e) Bronchial Tubes, (d) Right Lung, (c) Lobes of Lung.
It is a good practice to spend a few minutes early in the morning, in drawing into the lungs all the air they can possibly hold. Then breathe out slowly, by keeping the lips almost closed. While doing so, rapidly thump the chest and ribs with the flat sides of your fists. This will expand your lungs and prevent the congestion or settling of blood among many of the organs, besides strengthening and toning up the system.
PROPER USE OF CLOTHING.
Your parents furnish you with warm, comfortable clothing, but much depends on you whether it shall help preserve your health. Children often catch cold and more serious diseases by carelessness about their dress. Be careful that all your garments sit well and are not loose enough to annoy you, nor tight enough to cause discomfort.
Boys should lay off their overcoats and overshoes, girls their wraps and overshoes when they enter a warm room. Always put them on before going out in the cold or wet. Neglect in following this rule has often caused pneumonia and death.
DAMP CLOTHING.
If the clothing, shoes or stockings become wet, they should be changed at the earliest moment. If there is no chance to make such change, keep in motion until the garments can be replaced by others. If the moisture has reached the skin, it should be rubbed with a rough towel until dry and warm.
DANGERS TO HEALTH.
Before summer sets in, children are often tempted to sit or lie on the damp earth. This is hurtful and never should be done, even in warm weather.
