think about what the alveoli does...
|
|
|
Why is the left side of the heart thicker that the right side of the heart?
|
the left side of the heart carries oxygenated blood, therefore it pumps pressured blood quickly and efficiently, compared to the right side of the heart which pumps deoxyginated blood towards the heart and is not under any pressure.

|
|
Why should blood pressure not be too high?
|
as it is near to the kidneys, it can cause the capillaries to burst which can damage the alveoli.
