Which one of the following organs in the human body is most affected due to shortage of oxygen?
1 Intestine
2 Skin
3 Kidney
4 Brain
Explanation:
The brain represents just \(2 \%\) of body weight, yet it uses about \(20 \%\) of the body's oxygen supply. Without it, the brain can't perform even the most basic functions. The brain relies on glucose to power neurons that control everything from conscious functions like planning and thought to automatic unconscious processes like heart rate and digestion. Without oxygen, the brain's cells cannot metabolise glucose, and therefore cannot convert glucose into energy. When your brain is deprived of oxygen, then, the ultimate cause of brain death is inadequate energy to power the brain's cells

Name the pulmonary disease in which alveolar surface area involved in gas exchange is drastically reduced due to damage in the alveolar walls.
1 Pleurisy
2 Emphysema
3 Pneumonia
4 asthma
Explanation:
Empysema is a chronic respiratory disease where there is over-inflation of the air sacs (alveoli) in the lung, causing a decrease in lung function and often, breathlessness. In this disease, the alveolar walls are damaged leading to drastic reduction in gas exchange.

Which one of the following is the correct staement for respiration in human
1 Neural signals from pneumotaxic centre in pons region of brain can increase the duration of inspiration
2 Cigarette smoking may lead of inflammation of bronchi
3 About \(20-25 \%\) of carbon dioxide \(\left(\mathrm{CO}_{2}\right)\) is carried by haemoglobin as carbamino haemoglobin
4 Workers in grinding sandstone - breaking industries may suffer, from Asthma
Explanation:
Nearly 20-25 per cent of \(\mathrm{CO}_{2}\) is transported by RBCs whereas 70 per cent of it is carried as bicarbonate. About 7 per cent of \(\mathrm{CO}_{2}\) is carried in a dissolved state through plasma.

Name the chronic respiratory disorder caused mainly by cigarette smoking
1 Respiratory alkalosis
2 Emphysema
3 Asthma
4 Respiratory acidosis
Explanation:
Emphysema, is a condition where walls seperating the alveoli breaks and results in the reduction of surface area for the exchange of respiratory gases. The main reason for emphysema is smoking of cigarette.
