BREATHING
1.
Breathing is important for two reasons. It is the only means to supply our bod
for two reasons. It is the only means to supply our bodies and its various organs
with oxygen which is vital for our survival. The second function of breathing is
for our survival. The second function of breathing is that it is one means to get
rid of waste products and toxins from the body.
Oxygen is the most vital nutrient for our bodies. It is essential for the integrity
ain, nerves,
glands and internal organs. We can do without food for weeks and without water for days, but without
oxygen, we will die within a few minutes. If the brain does not get proper supply onnisessa
it will result in the degradation of all vital organs in the body.

The brain requires more oxygen than any other organ. If it doesn't get enough, the result is mental
sluggishness, negative thoughts and depression and eventually, vision and hearing decline. Old people
and those whose arteries are clogged often become senile and vague because oxygen to me
reduced. They get irritated very quickly.

Poor oxygen supply affects all parts of the body. The oxygen supply is reduced to all parts of the body as we

get older due to poor lifestyle. Many people need reading glasses and suffer hearing decline in old age.
When an acute circulation blockage deprives the heart of oxygen, a heart attack is the result. If this
occurs to the brain, the result is a stroke.
For a long time, lack of oxygen has been considered a major cause of cancer. Even as far back as 1947,
work done in Germany showed that when oxygen was withdrawn, normal body cells could turn into
cancer cells.
Similar research has been done with heart disease. It showed that lack of oxygen is a major cause of heart
disease, stroke and cancer. The work done at Baylor University in the USA has shown that you can reverse
arterial disease in monkeys by infusing oxygen into the diseased arteries.

Answer 1

These paragraphs explain the importance of breathing that its vital for our survival that includes survival of our body organs e.g. brain heart etc. We can live without food but not without oxygen. Lack of oxygen can cause cancer, heart attack as well as damage our vital organs, and it badly affect our vision and hearing power. Its disadvantages are proved by Universities of USA on base of various things which clearly shows its importance.
