Conclusion

==========

My evidence shows me that the more weight you carry, the higher your

pulse rate becomes.

The trend shown by my graph is that the line starts by increasing

rapidly, then starts to level out when the student is carrying 30

Newtons.

The science that explains this trend is that the muscles required for

climbing up the stairs need a constant supply of blood, containing

oxygen and glucose for energy. Oxygen is diffused into the blood

through breathing in air into the lungs; this travels through the

bronchi and bronchioles to the alveoli. The oxygen is diffused into

the capillaries and into the blood network. The red blood cells carry

the oxygen to the muscles. (The blood also picks up glucose from the

digestive system.)

Then the blood goes through the capillaries that run past the muscle
