In our Biology class we are studyng respiration so we make the following activity.

1 – State the uses of energy in our body.

The uses of energy are  for:

  1. Contracting muscles,so that we can move parts of the body.
  2. Making protein molecules by linking together amino acids into long chains.
  3. Cell division,so that we can repair damaged tissues and can grow.
  4. Active transport,so that we can move substances across cell membrane up their concentration gradients.
  5. Transmitting nerve impulses,so that we can transfer information quickly from one part of the body to another.
  6. Producing heat inside the body,to keep the body temperature constant even if the enviroment is cold.

2 – Construct a mind map about respiration.

here is the link

(point 3 is in the map!)

4- Search in the internet a short video, which explains why the breathing rate does not return to normal immediately after vigorous exercise stops.
