haemoglobin and myoglobin

hello everyone,
It is my first time on this site after hearing such fantastic things about it and the people.
I am hoping there is someone who could explain, the difference between haemoglobin and moglobin, i understand that they our a protein, and that they bond to oxygen and this bond can be broken when needed by the muscle tissue. however i am desperate to find out why there is a diffence between, and what is it and how does it work.
anything will be greatly appreciated, thank you so much.
