respiration revision Flashcards
What happens to cells without energy?
They die
What are the reactants of aerobic respiration?
Glucose + Oxygen
What are the products of aerobic respiration?
Carbon Dioxide + Water
Is energy a chemical substance?
No
How is glucose supplied?
Through the digestion of carbohydrates
Where is glucose absorbed into the blood?
The small intestines
Where does the blood travel?
In the blood vessels
Which system are the heart and blood vessels in?
The circulatory system
Which system are the lungs in?
The respiratory system
Where is oxygen diffused into the blood?
The alveoli
Which cells carries Oxygen around the body?
Red blood cells
What is tissue fluid made of and what do cells take from it?
Oxygen and glucose
Where does tissue fluid come from?
Capillaries around the body
What do cells produce and put back into the tissue fluid?
Carbon Dioxide
After the tissue fluids soaks back into the capillaries, what does the waste Carbon Dioxide do?
Dissolve in blood plasma
Where does blood go after being diffused in the lungs?
The capillaries
Where does the Carbon Dioxide from the tissue fluid go to after being dissolved by cells?
It diffuses out of the blood into the air and out of the lungs, hence why we breathe out Carbon Dioxide
Carbon Dioxide is e_______ out of the lungs
Carbon Dioxide is excreted out of the lungs
What is the process called when Oxygen is diffused into the blood and Carbon Dioxide out of the blood?
Gas exhange
What is the process called when cells take Oxygen and glucose out of the tissue fluid and put Carbon Dioxide into the blood?
Respiration
Why does your breathing rate and heart rate increase during exercise?
Your cells need more Oxygen and glucose for respiration
