Examining links between respiration and body systems
 Respiration is vital for living things.
 But respiration in your body relies on your body systems.
 Consider where the glucose used in respiration comes from and
where the carbon dioxide formed during respiration goes to.
Respiration and body systems
You have many systems in your body, each with a specific function.
The breathing system is responsible for
taking oxygen into our bodies and
passing carbon dioxide out
The digestive system is
responsible for digesting food
The circulatory system is responsible
for transporting substances around the
body
 The functions of all three body systems are linked with respiration.
 Glucose needed for respiration is produced by the digestion of carbohydrates in
the digestive system.
 Oxygen needed for respiration is brought into the body by the breathing system.
 Also, carbon dioxide and water produced by respiration are removed by the
breathing system.
 All these reactants and products are carried to and from cells by the circulatory
system.
List the three body systems associated with respiration.
Describe where glucose is carried from and to by the
circulatory system.
Suggest why carbon dioxide and water are sometimes
described as waste products of respiration.
A weak link
 Because respiration and some body systems rely on one another, there would be
problems if either respiration or the body system did not function properly.
 For example, if the digestion of carbohydrates is inefficient, there may not be
enough glucose for respiration.
 This results in insufficient energy being released.
 If the circulatory system is damaged this decreases the amounts of glucose and
oxygen delivered to cells.
 Again, insufficient energy is released in the body.
Describe how a failure of the breathing system could affect
respiration.
Explain why a decrease in the amount of respiration could negatively
affect digestion.
Draw a table to explain how a failure in each system (breathing,
digestive and circulatory) could negatively affect respiration.
What about plants?
 Plants make the glucose needed for respiration in their leaves.
 The glucose is then dissolved and transported around the plant in a
system of tubes called phloem.
 Phloem tubes are sometimes compared with blood vessels in animals.
 Oxygen enters a plant through pores on the underside of leaves.
These pores are called stomata
Suggest which system in animals corresponds to the transport system
(by phloem) in plants.
Suggest how carbon dioxide leaves a plant.
Did you know…?
 Plants can store excess glucose as starch in their roots.
 So, when we eat root vegetables such as potatoes, carrots and
turnip, we are actually eating the starch storage organ of a plant.
