1.4 i) Know the cardiac cycle (atrial systole, ventricular systole and cardiac
diastole) and relate the structure and operation of the mammalian heart,
including the major blood vessels, to its function.
ii) Know how the relationship between heart structure and function can be
investigated practically.

I understand the first part but what do they mean by 'relating to it's function.
And I have no idea about ii)

any help would be amazing!
Thanks.
