Hatha Yoga/Chapter 7 > 자유게시판

The Organs of Respiration encompass the lungs and the air passages resulting in them. The lungs are two in quantity, and occupy the pleural chamber of the thorax, wireless blood oxygen check one on every facet of the median line, being separated from one another by the center, the larger blood-vessels and the larger air tubes. Each lung is free in all instructions, besides at the basis, which consists chiefly 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 covered with a delicately constructed however robust sac, known as the pleural sac, one wall of which closely adheres to the lung, and the other to the inner wall of the chest, and which secretes a fluid which allows the inner surfaces of the walls to glide simply upon each other in the act of respiration. The Air Passages include the inside of the nostril, pharynx, larynx, windpipe or trachea, and the bronchial tubes.

Once we breathe, we draw in the air via the nose, wireless blood oxygen check through which it's warmed by contact with the mucous membrane, BloodVitals SPO2 which is richly provided with blood, and after it has handed via the pharynx and larynx it passes into the trachea or windpipe, which subdivides into quite a few tubes called the bronchial tubes (bronchia), which, in flip, subdivide into and terminate in minute subdivisions in all of the small air areas within the lungs, of which the lung's contain thousands and thousands. A author has said that if the air cells of the lungs were spread out over an unbroken floor, they would cowl an area of fourteen thousand square feet. The air is drawn into the lungs by the action of the diaphragm, an important, robust, flat, sheet-like muscle, wireless blood oxygen check stretched throughout the chest, separating the chest-field from the abdomen. The diaphragm's action is sort of as computerized as that of the center, although it could also be reworked into a semi-voluntary muscle by an effort of the will.

When it expands, it will increase the scale 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 bit into the matter of the circulation of the blood. The blood, as you know, is pushed by the center, by the arteries, into the capillaries, wireless blood oxygen check thus reaching every a part of the physique, which it vitalizes, nourishes and strengthens. It then returns via the capillaries by another route, the veins, to the heart, from whence it is drawn to the lungs. The blood begins on its arterial journey, vivid purple and rich, laden with life-giving qualities and properties. It returns by the venous route, poor, blue and dull, BloodVitals SPO2 being laden down with the waste matter of the system. It goes out like a contemporary stream from the mountains; it returns as a stream of sewer water.

This foul stream goes to the fitting auricle of the heart. When this auricle becomes filled, it contracts and forces the stream of blood via an opening in the best ventricle of the center, which in turn sends it on to the lungs, the place it's distributed by thousands and thousands of hair-like blood vessels to the air cells of the lungs, of which we have now spoken. Now, let us take up the story of the lungs at this point. The foul stream of blood is now distributed among the tens of 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 through the thin partitions of the hair-like blood vessels of the lungs, which partitions are thick sufficient to hold the blood, but skinny sufficient to admit the oxygen to penetrate them. When the oxygen comes involved with the wireless blood oxygen check, a type of combustion takes place, and the blood takes up oxygen and releases carbonic acid gasoline generated from the waste products and 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 center, once more wealthy, red and bright, and laden with life-giving properties and qualities. Upon reaching the left auricle of the center, it's pressured into the left ventricle, from whence it is once more forced out by the arteries on its mission of life to all elements of the system. It's 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 both of their surfaces. When one considers the minute details of the process alluded to, he is misplaced in surprise and admiration at Nature's infinite care and intelligence. It will be seen that unless recent air in adequate portions reaches the lungs, the foul stream of venous blood can't be purified, and consequently not solely is the physique thus robbed of nourishment, but the waste products which should have been destroyed are returned to the circulation and poison the system, and demise ensues.
