Science / Respiration in organisms

  • Respiration releases energy from food. The oxygen that we inhale breaks down glucose into carbon dioxide and water. This releases the energy.lungs
  • Aerobic respiration uses oxygen to breakdown the food. Anaerobic respiration does not use oxygen.
  • For example, when we exercise, our muscles do not have enough oxygen. Therefore, the muscles breakdown food without the oxygen.
  • Breathing is a process of respiration during which oxygen is inhaled and carbon-dioxide is exhaled.
  • Humans and animals use lung as the respiratory organ. Earthworm breathes through its skin and fish uses its gills. Plants use their leaves and roots to take in air.

Respiration can be measured using a device called a Respirometer.

We exhale about half a liter of water vapour in a day.

Human breathing mechanism is called tidal breathing as air comes in and out using the same path.
