            1. Leucocytes. About 65 per сёAt df all white cells are leucocytes. Their protoplasm contains granules. Those leucocytes that stain neutral dyes — as the majority do — are called neutrophils. About 1.5 per cent of the total stain with acid dyes and are called eosinophils. And a still smaller number, 0.5 per cent, have granules that stain with basic dyes; these are called basophils. The percentage of oesinophils increases greatly when parasites invade the body. ; ^ ...

            2. One characteristic of leucocytes is the irregular, or lobed, appear­ance of the nucleus. The number of lobes is an index to the cell's age. Ordinarily, about 45 per cent of all leucocytes have a nucleus of three lobes. The life span1 of a leucocyte is short, from four to twelve days.

            3. /The function of leucocytes/s primarily that of protection against infection. After the skin is pierced and the wound becomes infected, leucocytes from all the body are attracted to this place. Just what at­tracts them is not known — the process is called chemotaxis — probably some by-product of bacterial metabolism. When they arrive at the wound, they leave the blood stream. They wage war on the invaders, engulfing the bacteria within their own protoplasm, a process called phagocytosis (literally «cell-eating»). Before the infection is not too overwhelming, the victory usually goes to the leucocytes.

They are produced in lymph nodes scattered throughout the body; the tonsils are examples of lymph nodes. They live only a few hours after they leave the blood stream. They are incapable of movement and thus cannot pursue bacteria and have little cytoplasm so that phagocytosis is practically out of the question, bacteria trapped in lymph node$ provoke the form^ti^n of them^j Unfortunately if the infection is overw^elmi!^ the lymbfiV nodes themselves become infected. Thus in guinea pigs it has been pos­sible to trace the route of tubercle bacilli from the intestines to the lungs, as the route is marked by successively infected lymph nodes.

Text В

Nature оf the Heart Beat

The fact that the heart, completely removed from the body, will go on to beat for a time shows that its beat is «automatic», i.e., does not require nerve impulses.

The beat is rhythmic: it is not jerky; the ventricles relax fully before the next contraction. This is explained by a special property of cardiac muscle tissue. The period of time during which the muscle is not re­sponsive to a stimulus is called the refractory period. It is characteristic of the heart muscle to have a long refractory period. When the heart muscle is stimulated, it will contract but will not respond again to that stimulus (though it may respond to a stronger one) until it has relaxed. This rest period is occupied by the heart filling with blood, in prepara­tion for the next beat. Even the heart forced to beat rapidly maintains a perfectly rhythmic beat; although the beats come closer together, there is always that little rest period in between.

The heart is a pump, but a double pump; the volume expelled by the right ventricle is the same as that expelled by the left. When exercise is suddenly undertaken, the «venous return», i.e. the blood returned to the heart through the veins, is suddenly increased. For a few beats the right ventricle does put out more blood than the left, but soon the additional blood has passed through the lungs and is entering the left ventricle, l Yom then on, both put out the same amount.

The Cardiac Output

Cardiac output refers to the volume of blood which the left ventricle forces into the aorta per minute of time. It must be noted that this term refers to the output of the left ventricle only, and that the total output is twice as much. The reason that the output of the left ventricle is given this special name is that it supplies the entire body (except the lungs) with the blood. Another xeason is that it does a much greater amount of work than does the right, and consequently is more likely to fail.

Cardiac output is the product of two factors: heart rate (the number of beats per minute) and stroke volume (the volume expelled per beat).

  1. The heart rate is normally controlled by a balance between impuls­es reaching it over the vagus and over the sympathetics. Thus, inhibition of the vagus centre speeds up the heart. And inhibition of the sympa­thetic centre slows down the heart. It seems that in the human most of the effect is achieved by inhibition of the vagal centre of the sympathetic region.

  2. The second factor affecting cardiac output is the stroke volume, that is, the amount of blood which the left ventricle ejects per beat. The stroke volume depends upon the «venous return». The normal heart is capable of a considerable degree of enlargement; after the venous return is increased - as it is in exercise — the chambers of the heart are able to supply the additional blood. The walls Of right atrium and the great veins are thin and stretch readily; therefore the heart rate is increased.

The increased venous return in exercise is brought about in the fol­lowing manner: 1) after muscles contract, they exert a «milking» effect on the blood vessels which they contain. With each contraction, blood is squeezed out1 into the veins; it cannot be squeezed back into the arteries because the arterial pressure is high - and with each relaxation the blood vessels of the muscle again fill up with blood; 2) in exercise, breathing becomes deeper. The heart lies within the thorax; when the thorax expands, blood is «sucked2 into» the heart.

The two factors, working together, lead to the increase of the blood amount returned. First the right side of the heart, and within a few beats the left, are dilated and take bigger «bites» of blood. Thus the stroke volume is increased.

Movements of Breathing Mechanism of Inhalation and Exhalation

1. Respiration consists of rhythmically repeated inhalations and ex­halations. Inhalation takes place as follows: fthe muscles participating in inhalation contract under the influence of nerve impulse^/ While contracting the diaphragm descends (flattens) increasing the vertical size of thoracic cavity. Сontraction of the external intercostal and cer­tain other muscles elevates the ribs increasing both the anteroposte­rior and transverse size of the thoracic cavity^Thus muscular contrac­tion increases the capacity of the thorax. Since the pleural cavity contains no air and the pressure in it is negative both lungs expand
