8.0 8.30 (Daventry only) Mr. NORMAN WALKER: ' Next Steps in Biology-VI, The Ventilation of our Bodies.' Relayed from Leeds
MR. WALKER'S series of biological talks-whose aim has been to help listeners to learn something of science at first hand, by performance of experiments, and by making direct observations-comes to a close with this talk, on the ventilation of our bodies. The experiments with blood that were begun on May 28 are continued ; we learn how the blood reaches the living tissues, and we watch the work of the red blood-cells. We all understand, these days, the importance of ventilating our rooms ; but the ventilation of our bodies, through the great windows of the lungs, is still too infrequently given the serious consideration it demands.
