What reading level is Maintaining Health book?
To quickly assess the difficulty of the text, read a short excerpt:
The sebumserves as lubricant. It is generally discharged near or at the shaft ofa hair. The sweat glands discharge on the average from one and one-half to twopounds of perspiration per day, more in hot weather and much less whenit is cool. They are distributed over the whole external surface of thebody. According to Krause there are almost 2, 400, 000 of them. They carryoff water and carbonic acid gas chiefly. The functions of the skin are: To protect the underlying structures; toregulate the h...eat; to serve as an organ of respiration; to serve as anorgan of touch and thermal sensation; to secrete and eliminate varioussubstances from the body; to absorb. The heat regulation is quite automatic. When the external temperature ishigh there is a relaxation of the skin. The pores open, the perspirationgoes to the surface and evaporates, thus cooling the body. When thesurface is cool the skin contracts, closing the pores and conserving theheat. Radiation always takes place, except when the temperature is veryhigh.
