1 of 19
Where does gas exchange take place?
In the alveolus
2 of 19
What is the function of the left side of the heart?
Pump blood to the arteries where it picks up oxygen.
3 of 19
What does the structure of the capillary walls help with and how is it adapted?
Get fluid out of blood, it's adapted by having the capillary have very thin walls and tiny gaps for it to leak out of.

What is the function of the right side of the heart?
pump blood around the rest of the body.
5 of 19
What do the air sacs contain a number of tiny pockets in?
a number of tiny pockets called alveoli.
6 of 19
)What fluid leak out of the capillaries and what does it contain?
tissue fluid and contains glucose.

What 3 vessels does blood flow in?
arteries, veins and capillaries.
8 of 19
What is the trachea?
windpipe, which is the middle bit of the lungs.
9 of 19
What are the things that spread out on the air sacs called?
bronchus.

What goes into the alveolus when it's breathed out, and inhaled oxygen enters the capillary?
Carbon dioxide goes into the alveolus when it's breathed out, and inhaled oxygen enters the capillary.
11 of 19
What does aerobic respiration release energy from glucose using the ____ system?
energy from glucose using the digestive system, which gets into the blood.
12 of 19
What is the equation for aerobic respiration?
[Reactants] Oxygen + Glucose ~> [Product] Carbon dioxide + Water
13 of 19
Why do athletes drink energy drinks?
[Reactants] Oxygen to replace water, salts and more important things required like glucose for more energy, and drinking energy drinks provides energy faster.+ Glucose ~> [Product] Carbon dioxide + Water

What do cells use digested food for?
energy, warmth and movement.
15 of 19
Red bloods cells carry what to the body tissue?
Red blood cells carry oxygen to the body tissue.
16 of 19
What does glucose dissolve in?
Glucose is dissolved in the plasma, the colourless watery fluid of the blood.
17 of 19
As exercise increases, what happens to the breathing rate?
As exercise increase the breathing rate goes up.
18 of 19
What does the circularity system do?
The circularity system carries oxygen and glucose around the body.
