The _________ omentum is an apron-like fold of peritoneum that hangs from the greater curvature of the stomach
Greater
Ligaments on the right side of the liver from the _________ and ___________ spaces
Subphrenic,and subhepatic
The ______________ hepatis ascends from the umbilicus to the umbilical notch of the liver within the free margin of the falciform ligament before coursing within the liver
Ligamentum teres
The paired _________ abdominis muscles are delineated medially in the midline of the body by the linea alba
Rectus
The amount of intraperitoneal fluid depends on the ________, ___________, and patient ___________
Location, volume and position
The ascitic fluid first fill the _____________ then the lateral paravesical recesses before is ascends to both paracolic gutters
Pouch of Douglas
The small bowel loops __________ or ___________ in the surrounding ascitic fluid, depending of relative gas content and amount of fat in the mesentery
Floats or sinks
Inflammatory or malignant ascites appears with ____________ echoes; loculation ; unusual distribution, matting, or clumping of the bowel loops; and thickening of interfaces between the fluid and neighboring structures
Fine or coarse internal
A cavity formed by necrosis within a solid tissue or a circumscribed collection of purulent material is a
Abscess
Name the five major pathways through which bacteria can enter the liver and cause abscess formation
- Through the portal system
- By way of ascending cholangitis of the common bile ducts
- Via the hepatic artery secondary to bacteremia
- By direct extension from an infection
- By implantation of bacteria after trauma to the abdominal wall
