Check references on University assignment

An assignment for a surgical first assistant student studying at dmu (Leicester)

Could you please check the bibliography and my references. I am fine with the content of my assignment and spelling, grammar etc.

Just need you to check my references especially within the bibliography, because I haven't wrote an assignment in 10 years.

The reference system dmu uses is Harvard referencing system. All the content for my references is there. Just please check the order of them etc.

Assignment is roughly 2,500 words with about 20 references.

Thanks so much
