Description
Active body cells require lots of oxygen for energy production in aerobic respiration as we learnt in Lecture IV. A major by product of aerobic respiration is carbon dioxide. Carbon dioxide dissolves in water to form carbonic acid and hence disturbs acid base balance in the body. Accumulation of carbon dioxide is therefore toxic to the cells as it may cause acidosis. Living cells have mechanisms of intake of oxygen and elimination of carbon dioxide. The two gases are known as respiratory gases. In small organisms such as protozoans the body surface provides an adequate surface area for the exchange of respiratory gases by diffusion. In mammals and other higher animals there are specialized systems for exchange of respiratory gases.

SERVICE TECHNICAL SKILLS
1. Lay the napkin face down in front of you.
2. Fold the napkin in half.
3. Fold the napkin in quarters.
4. Fold the napkin in half diagonally, creating a triangle.
5. Orient the triangle so the open tip is facing away from you.
6. Fold the right corner diagonally towards you – laying it down along the centreline of
the triangle, making a new tip pointing towards you. An iron can make this important
fold a whole lot easier.
7. Do the same with the left corner, fold it diagonally toward you and press it down next
to the previous fold. Now you have a diamond, you’re rich! Yay!
8. Fold the two "wings" that you just made in folds 6 and 7 under so that you have your
original triangle shape back. Once again an iron can make a world of difference.
9. Fold the triangle in half by bringing the centre seam towards you and allowing the
ends to fall.
10. This bird’s almost ready to fly, but first you must give it some feathers. While holding
the base firmly to keep your folds together, pull up the four ‘flaps’ created by the
napkin’s corners
