Prana and Lungs – Part 2


It is through vocal cords that are located in the larynx that sound is produced. Larynx is the sounding box. When the vocal cords are affected by too much straining, as in singing and continuous lecturing, the voice becomes hoarse. In females these cords are shorter. Hence they have a sweet melodious voice. The number of respiration per minute is 16. In pneumonia it is increased to 60, 70, 80 per minute. In Asthma, the bronchial tubes become spasmodic. They contract. Hence there is difficulty in breathing. Pranayama removes the spasm or constriction of these tubes. A small membranous flat cap covers the upper surface of larynx. It is called Epiglottis. It prevents the food particles or water from entering into the respiratory passage. It acts the part of a safety valve. When a small particle of food tries to enter the respiratory passage, cough comes in and the particle is thrown out.

Lungs purify the blood. The blood starts in its arterial journey, bright-red and rich-laden with life-giving qualities and properties. It returns by the venous route, poor, blue-laden with the waste matter of the system. Arteries are tubes or vessels that carry pure oxygenated blood from the heart towards the different parts of the body. Veins are vessels or tubes that carry back impure blood from the different parts of the body. The right side of the heart contains impure venous blood. From the right side of the heart the impure blood goes to the lungs, for purification. It is distributed among the millions of tiny air-cells of the lungs. A breath of air is inhaled and the oxygen of the air comes in contact with the impure blood through the thin walls of the hair-like blood-vessels of the lungs called pulmonary capillaries. The walls of the capillaries are very thin. They are like muslin cloth or sieve. Blood oozes out or exudes readily. Oxygen penetrates through the walls of these thin capillaries. When the oxygen comes in contact with the tissues a form of combustion takes place.

The blood takes up oxygen and releases carbonic acid gas generated from the waste products and poisonous matter, which has been gathered up by the blood from all parts of the system. The purified blood is carried by the four pulmonary veins to the left auricle and thence to the left ventricle. From the ventricle it is pumped into the biggest artery, aorta. From aorta, it passes into the different arteries of the body. It is estimated that in a day 35,000 pints of blood traverses the capillaries of the lungs for purification.

From the arteries the pure blood goes into the thin capillaries. From the capillaries the lymph of the blood exudes, bathes and nourishes the tissues of the body. Tissue respiration takes place in the tissues. Tissues take up the oxygen and leave the carbon dioxide. The impurities are taken by the veins to the right side of the heart.

Who is the creator of this delicate structure? Are you feeling the invisible hand of God behind these organs? The structure of this body bespeaks undoubtedly of the omniscience of the Lord. The Antaryamin or the Indweller of our hearts supervises the working of the inner factory as Drashtha. Without His presence, heart cannot pump blood into the arteries. Lungs cannot carry out the process of purifying the blood. Pray. Pay your silent homage to Him. Remember Him at all times. Feel His presence in all the cells of the body.
