Circulatory and Respiratory System Notes

 

Digestive System	Respiratory System	Circulatory System
Digest (breaks down) food.   Digested food is then absorbed via the small intestine into the bloodstream to be carried to other parts of the body (eg hands, legs, brain, etc)	Provides oxygen to other parts of the body for respiration (releases energy).   Removes waste products of respiration such as carbon dioxide and water from other parts of the body	Transports blood rich in oxygen and digested food TO other parts of the body. > Blood is transported AWAY from the heart   Transports blood poor in oxygen and rich in carbon dioxide FROM other parts of the body. > Blood is transported TOWARDS the heart

 

1.     [C] Our breathing rate increases.

[E/R] Our body parts such as muscles in our hands and legs need more energy. More oxygen and more digested food is needed to be transported to these body parts to produce more energy by respiration.

 After respiration, more waste products such as carbon dioxide and water need to be removed.

 

2.     [C] Our heart rate increases.

[E/R] This cause blood to be pumped faster to carrying more oxygen and more digested food to other parts of our body for respiration to provide more energy.  More carbon dioxide will also be removed faster
