NOW IS THE TIME TO REAWAK
 FEN YOUR ASPIRATION

Pray do not be alarmed. This k strictly physiological vite talk. Or call it a pep talk if your I. o. is low
 The heart pumps blood into the arteries-everybody, except maybe some university students on radio quiz programs, knows that. Having pumped it's load of blood 6 or ( ounces to the beaD into the aorta or great artery, the heart relaxes or rests moment, and the aortic valve closes so that the blood cannot flow back into the heart again. The elastic rebound of the aorta and other arteries helps to drive the blood along to smaller branch ar- teries, and contraction Of voluntary muscles of the body increases the pressure upon the arteries and aids in propelling the blood on into the finest vessels visible even with the microscope, the arterioles.
 Beyond the arterioleS there are nc blood vessels of any description. The conception of capillary vessels bridging the gap between arterioles and the finest visible veins, venules, is purely hypothetical, and even the hypothesis serves no purpose. Be- yond the arterioles the blood simply seeps through the tissue, filters through between the tissue cells or flores, where it gives its oxygen and fuel or nutriment to the tissue cells and picks up it's load of carbon di- oxide and ash or combustion prod ucts to carry away. .,
 Is the blood in the capillary bed, as it IS called, under pressure? Ger tainly it is, for their wise blood would not ooze from a scratch, puncture or small cut at all.
 Now the carrying of blood from the heart to the tissues seems clear enough. But it is not SO easy to understand how the blood is carried back from the tissues to the heart and lungs for ventilation and puri- fication and refIeling (the refueling occurs mainly in the liver). What force drives the blood through the veins back toward the heart? The blood in the veins is no longer pro- pelled by the pumping of the heart But there is more or less constant pressure upon the veins by the vol untary muscles and by some invol- untary muscle tissue in the ali mentary tract for example; even al rest these muscles maintain moder- ate pressure upon the veins (anC the arteries too by their "tone" ol firmness or elasticity. Then the veins, at least the veins in parts oi the body that are vertical wher the body is in the natural horizonta. position (on all fours), unlike the arteries, are equipped with valves which permit the blood to flow back toward the heart under pressure but prevent it from backing up to. ward the tissue bed.
 Even that would not maintain 6 very efficient circulation without tht aid of aspiration.
 Aspiration means the suction ef- feet upon the blood in the large veins such as the portal veins ir the liver region and the great trunk veins Supporter and inferior vena cava) which finally carry the blooc back to the heart, suction due tc the negative pressure or tendency te vacuum produced within the cheSt cavity by the act of inspiration, in. halation, taking breath of air
 Of course the effect of aspirat tior varies with the eficiency and man. ner or perhaps we should say habit of breathing.
