It follows that the deeper the inspiration the greater the difference he-, tween the intra-thoracic and the atmospheric pressure. Bv«n in expiration, except when forced, the intra-thoracic preamre remains leas, for the same reason. These conditions must have an influence on the heart and blood-vessels. Bearing in mind that the pressure without is practically constant and always greater than that within the thorax, the conditions are favorable to the flow of blood toward the heart As in in^iration, the pressure on the great veins and the heart is diminished, and, as these organs are not rigid, they tend to expand within the thorax, thus favwing an on- waid flow.
