Question

Read the sources given and answer any four from the questions given below:

Alcohol is rapidly absorbed in the body tissues as it does not need to be digested. It gets absorbed through the lining of stomach and intestine and enters the blood within two minutes of being swallowed. In no time it reaches all the body cells, where its oxidation begins immediately. As the cells oxidise alcohol, a large amount of heat is produced. This excess heat by the body is carried by the blood. This raises the temperature of blood and leads to increased circulation towards the skin for dissipation of heat. The skin turns rosy and the person may get a false impression of warmth. Actually, as the blood is directed towards the skin, the supply of blood to internal organs is reduced bringing a fall in their temperature. Alcohol has no value as a food as the energy released is not used in any life processes. Alcohol affects the central nervous system. Alcohol is a depressant and not a stimulator as many people think.
