Nature of 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. From 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^эп1у, 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 icason 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).
-
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.
-
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 out 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
Respiration consists of rhythmically repeated inhalations and exhalations. Inhalation takes place as follows: jthe muscles participating in inhalation contract under the influence of nerve impulses. While contracting the diaphragm descends (flattens) increasing the vertical size of thoracic cavity. Contraction 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
simultaneously with the increase in capacity of the thorax.The lungs expanding, the air pressure in them drops and atmospheric air rushes into the lungs through the air passages. Hеnсе an inhalation involves a contraction of muscles, an increase in the capacity of the thorax, an expansion of the lungs, and entrance of atmospheric air into the lungs through the air passages.
-
Inhalation is followed by exhalation. The muscles participating in inhalation relax, |the diaphragm rising. The ribs drop as a result of contraction of the internal intercostal and other muscles and because of their own weight. The capacity of the thorax decreasing, the lungs become compressed, the pressure in them rises and the air rushes out through the air passages.
-
The respiratory movements are rhythmic. An adult at rest makes 16-20 respiratory movements per minute, children make more movements (a newborn child makes up to 60 movements a minute.). Physical exertion, particularly in untrained people, is usually accompanied by faster respiration. Accelerated respiration is also observed in many diseases. Sleep is accompanied by a slowing of respiration.
-
Movements of breathing. Changes in the volume of air in the lungs are brought about by movements both of the diaphragm and ribs. Contraction of the diaphragm increases the length of the capacity of the chest, while the upward movement of the ribs increases the cross section of the chest. Inspiration is due to contraction of the diaphragm and of the muscles attached to the ribs. These contractions are induced by nervous impulses. Expiration is a less active process than inspiration, for when the muscles relax the elasticity of the lungs themselves tends to drive out the air previously inhaled. Any impediment to breathing due to pressure or constriction in the respiratory passage is especially noticeable during expiration, because it is usually of a passive character.When the volume of breathing is increased by physical exercise many assessory muscles are involved while producing deeper inspirations. Expiration also involves a Vigorous action of the abdominal muscles.

1. For mechanical analysis the respiratory system may be divided into three parts: the gas (in the airways and air spaces), the lung structure, containing the gas, and the thorax containing the lungs. 2. Dynamic increases in airway resistance during expiration set the limit on the ventilatory capacity of the respiratory system in normal and diseased lungs. 3. While flowing through the capillaries the blood accepts the oxygen from the alveolus and deposits carbon dioxide into the alveolus. 4. Airway pressures are not everywhere equal, being most negative in the alveoli. 5. During inspiration pleural pressures become more negative, the widening tendency increasing.
