why is the heart suited to its funtion and why is the respiratory system suited to its function
Go back to those sites I gave you. What does the heart have that makes it the only thing that can do what it does?"
Isn't it amazing that where the heart is, two blood pumps are needed, one pump to pump blood through capillaries in the body, and another pump to move blood through a gas exchange system of capillaries.
What is more remarkable, the respiratory system seems to fit the need for a gas exchange system.
ive put about the pump and all that but i need more info on why its good at its job
