Giuliano Mignini, the chief prosecutor, said the wounds backed up the prosecution case that Ms Kercher was killed after refusing to take part in a drug-fuelled sex game.
Dr Lalli said there was no "biological evidence of a sexual attack," but it was likely that she had been subjected to "non- consensual sex" due to the number of bruises on her body.
Dr Lalli's evidence was held in private without any media or public present after a ruling by the judge following a request from the Kercher family.
Court sources said that American Knox, 21, did not look at the images as they were shown on a video screen and kept her head down while her coa-ccused and former boyfriend Raffaele Sollecito, 25, glanced at them sporadically.
Knox's mother Edda Mellas, who is in Perugia, Italy, to support her daughter said during a break in hearings: "The images upset her too much and she didn't watch them."
Francesco Maresca, the Kercher family lawyer, said that it could not be "ruled out that hasty sexual activity, which would not leave signs of resistance, had taken place after she had been threatened with a knife."
The trial continues.
