Hatha Yoga/Chapter 7 > 자유게시판

The Organs of Respiration encompass the lungs and the air passages leading to them. The lungs are two in number, and occupy the pleural chamber of the thorax, one on each aspect of the median line, being separated from one another by the heart, the higher blood-vessels and the larger air tubes. Each lung is free in all directions, besides at the basis, which consists mainly of the bronchi, arteries and veins connecting the lungs with the trachea and coronary heart. The lungs are spongy and porous, and their tissues are very elastic. They are lined with a delicately constructed but sturdy sac, known because the pleural sac, one wall of which intently adheres to the lung, measure SPO2 accurately and the opposite to the internal wall of the chest, and which secretes a fluid which permits the internal surfaces of the partitions to glide simply upon one another in the act of respiration. The Air Passages consist of the interior of the nose, pharynx, BloodVitals SPO2 larynx, windpipe or trachea, BloodVitals SPO2 and the bronchial tubes.

After we breathe, we draw within the air by the nostril, in which it's warmed by contact with the mucous membrane, which is richly provided with blood, and after it has handed by way of the pharynx and larynx it passes into the trachea or windpipe, which subdivides into numerous tubes referred to as the bronchial tubes (bronchia), which, measure SPO2 accurately in flip, subdivide into and terminate in minute subdivisions in all of the small air areas within the lungs, of which the lung's comprise thousands and thousands. A writer has stated that if the air cells of the lungs had been spread out over an unbroken surface, they'd cowl an area of fourteen thousand square toes. The air is drawn into the lungs by the action of the diaphragm, a fantastic, BloodVitals SPO2 robust, flat, sheet-like muscle, stretched throughout the chest, separating the chest-field from the abdomen. The diaphragm's action is nearly as automatic as that of the center, although it may be reworked right into a semi-voluntary muscle by an effort of the need.

When it expands, it will increase the size of the chest and lungs, and the air rushes into the vacuum thus created. When it relaxes the chest and lungs contract and the air is expelled from the lungs. Now, before contemplating what occurs to the air within the lungs, let us look a little bit into the matter of the circulation of the blood. The blood, measure SPO2 accurately as you know, is pushed by the center, by way of the arteries, into the capillaries, thus reaching each part of the body, measure SPO2 accurately which it vitalizes, nourishes and strengthens. It then returns by way of the capillaries by another route, measure SPO2 accurately the veins, to the center, BloodVitals insights from whence it's drawn to the lungs. The blood begins on its arterial journey, brilliant purple and wealthy, laden with life-giving qualities and properties. It returns by the venous route, poor, blue and dull, being laden down with the waste matter of the system. It goes out like a recent stream from the mountains; it returns as a stream of sewer water.

This foul stream goes to the precise auricle of the guts. When this auricle turns into filled, it contracts and forces the stream of blood by way of an opening in the precise ventricle of the center, which in flip sends it on to the lungs, the place it's distributed by millions of hair-like blood vessels to the air cells of the lungs, of which we have spoken. Now, allow us to take up the story of the lungs at this level. The foul stream of blood is now distributed among the many millions of tiny air cells within the lungs. A breath of air is inhaled and the oxygen of the air comes in touch with the impure blood by the skinny partitions of the hair-like blood vessels of the lungs, which walls are thick sufficient to hold the blood, but thin sufficient to admit the oxygen to penetrate them. When the oxygen comes in contact with the blood, a form of combustion takes place, and the blood takes up oxygen and releases carbonic acid gasoline generated from the waste merchandise and BloodVitals SPO2 poisonous matter which has been gathered up by the blood from all components of the system.

The blood thus purified and oxygenated is carried back to the heart, again rich, measure SPO2 accurately purple and shiny, and laden with life-giving properties and qualities. Upon reaching the left auricle of the heart, it's pressured into the left ventricle, from whence it is again compelled out through the arteries on its mission of life to all parts of the system. It is estimated that in a single day of twenty-4 hours, 35,000 pints of blood traverse the capillaries of the lungs, the blood corpuscles passing in single file and being uncovered to the oxygen of the air on each of their surfaces. When one considers the minute particulars of the method alluded to, he is misplaced in surprise and admiration at Nature's infinite care and intelligence. Will probably be seen that until recent air in enough quantities reaches the lungs, the foul stream of venous blood cannot be purified, and consequently not only is the physique thus robbed of nourishment, but the waste merchandise which ought to have been destroyed are returned to the circulation and poison the system, and dying ensues.
