perihepatic, parasplenal, paracolic gutters and cul-de-sac
Accessibility and _______ of performance are critical in the trauma setting.

Hemorrhage in the peritoneal cavity collects in the most
________ area of the abdomen.
______ lacerations or contusions are more easily detected with ultrasound than any other visceral abdominal injury.
A brisk intraparenchymal hemorrhage may be identified as a _________ region within the abnormal parenchyma, whereas a global parenchymal injury may project into the liver as a widespread architectural disruption with the absence of the normal vascular pattern.

With the bladder distended, the color doppler is an excellent tool to image the presence of ureteral jets into the bladder; the transducer should be angled a(n) ________ presentation through the distended urinary bladder.
The pulse repetition frequency should be ________ to assess the low velocity of the ureteral jet flow.

A(n) _________ forms when the abdominal wall muscles are weakened, which allows the viscera to protrude into the weakened abdominal wall
