The tidal range is the vertical difference between the high tide and the succeeding low tide. Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth.
The chart above shows volume of the lungs as a function of time. Tidal volume is a difference between volumes at normal inhalation and normal exhalation. Normal tidal volumes are much smaller in newborn, infants, and children, down to 150 ml due to their smaller lung sizes. Medical textbooks suggests that the normal value at rest is 500-600 mL for a 70-kg man.
