The subphrenic space is divided into right and left components by the _______________ ligaments.
falciform
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 the patient ______________.
location; volume; position

pouch of Douglas
The small bowel loops _____________ or _____________ in the surrounding ascitic fluid, depending on relative gas content and amount of fat in the mesentery.
floats; sinks
Inflammatory or malignant ascites appears with ________________ echoes; loculation; unusual distribution, matting or clumping of bowel loops; and thickening of interfaces between the fluid and neighboring structures.

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 duct
