Read the following passage anh mark the letter A, B, C or D on your answer sheet to

indicate the correct answer to each of the questions from 1 to 7.

Under certain circumstances, the human body must cope with gases at greater-than-normal

atmospheric pressure. For example, gas pressures increase rapidly during a drive made with

scuba gear because the breathing equipment allows divers to stay underwater longer and dive

deeper. The pressure exerted on the human body increases by 1 atmosphere for every 10 meters

of depth on seater, so thay at 39 meters in seawater a diver is exposed to pressure of about 4

atmosphere. The pressure of the gases being breathed must equal the external pressure applied

to the body, otherwise breathing is very difficult. Therefore all of the gases in the air breathed

by a scuba diver at 40 meter are present at five times their usual pressure. Nitrogen, which

composes 80 percent of the air we breathe, usually causes a balmy feeling of well-being at this

pressure. At a depth of 5 atmosphere, nitrogen causes symptoms resembling alcohol

intoxication, known as nitrogen narcosis. Nitrogen narcosis apparently results from a direct

effect on the brain of the large amounts of nitrogen dissolved in the blood. Deep dives are less

dangerous if helium is substituted for nitrogen, because under these pressures helium does not

exert a similar narcotic effect.

As a scuba diver descends, the pressure of nitrogen on the lungs increases. Nitrogen then

diffuses from the lungs to the blood, and from the blood to body tissues. The reverse occurs

when the diver surfaces, the nitrogen pressure in the lungs falls and the nitrogen diffuses from

the tissues into the blood, and from the blood into the lungs. If the return to the surface is too

rapid, nitrogen in the tissues and blood cannot diffuse out rapidly enough and nitrogen bubbles

are formed. They can cause severe pains, particularly around the joints.

Another complication may result if the breath is held during ascent. During ascent from a depth

of 10 meters, the volume of air in the lungs will double because the air pressure at the surface is

only half of what it was at 10 meters. This change in volume may cause the lungs to distend ang

even rupture. This the rise of the exhaled air bubbles, and must exhale during ascent.
