In addition to these, there are several types of glands which carry on their respective jobs in the human body.

Human body is made up of five elements: air, water, fire, earth and ether. These five elements are present in our body in the form of five sense organs. Ether has the characteristic of sound, which we hear with our ears. The characteristic of air is touch, which we feel with our skin. The characteristic of fire is light, which we feel with our eyes. The characteristic of water is taste which we feel with our tongue. And similarly, the characteristic of earth is smell, which we experience through our nose.
Man has five service organs: mouth, feet, hands, procreative organs and rectum.

Five service organs, five sense organs, the various centers or departments of the body and the glands-in all these 24 elements regulate the functioning of our body. But they are all controlled by the mind which is in turn controlled by the intellect. As the Hindu philosophy puts it, man’s ego controls his intellect and the master of ego is the soul.

Yogasanas influence the spinal cord, the muscles, the blood circulation centre, the nerve centre and the digestive organs. All these are closely connected with the heart, lungs, and the brain. It is, therefore, necessary to broadly explain the structure and functioning of these organs.
