The blood
carries for respiratory gases to their final destination, the cells or tissues.
Here, oxygen is utilized for metabolic purposes involving oxidation of
organic food, by a series of biotechnological reactions. These metabolic
reactions finally produce carbon dioxide, water and energy in the form of ATP,
e.g a dioxide, water and energy in the form of ATP, e.g, a single molecule of
glucose is metabolized by Glycolysis Kreb's cycle and then by Electron
Transport Chain in mitochondria aerobically to yield 36 molecules of ATP.
Similarly amino acids and fatty acids are also oxidized along their biochemical
pathways to produce energy. This is known as cellular respiration.
Carbondioxide, generated as a byproduct in these reactions is then eliminated
by expiration.
Lung-Function Test or Pulmonary-Function
Test (PET) is carried out
to measure volumes and capacity of lungs. It is measured using an instrument
known as spirometer.
