Respiration Flashcards
What is digested food used for
To provide glucose
What substance is the main energy resource
Glucose
How does oxygen get into the body and how is it transported through the blood
Oxygen gets in by breathing into the lungs, then it diffuses in, and it is transported through the blood due to the heart pumping it
What system does the heart belong to
Circulatory system
Why does the heart have to halves
One half pumps oxygenated blood and the other one deoxygenated blood
How does exercise affect heart and breathing rate
It accelerates it
How does the body get rid of carbon dioxide
By exhaling
How does oxygen go to each cell
By the capillaries
How are the lungs adapted
They have alveoli inside that are only one cell thick to make diffusion faster
How do gases get in and out of the blood
By diffusion, made possible by different amounts of gas in and out of the alveoli
How to detect water vapour
Cobalt chloride paper turns pink
How do you test carbon dioxide
Limewater turnas milky/cloudy
How are lunes kept clean
By the cilia which “wipe off” and dust or dirty ness inside the lungs
How is energy released
Through respiration
What are the similarities and differences between burning and respiration
Both use oxygen and produce carbon dioxide
The fuel for respiration is glucose and for burning, the fuel could be anything and when you respire, you don’t make a flame, in burning, a flame is made
