,Chapter 1: Cell Adaptation, Injury and Death
Ischemia and other toxic injuries increase the accumulation of intracellular calcium as a result
1. of:
A) release of stored calcium from the mitochondria.
B) improved intracellular volume regulation.
C) decreased influx across the cell membrane.
D) attraction of calcium to fatty infiltrates.
The patient is found to have liver disease, resulting in the removal of a lobe of his liver.
2. Adaptation to the reduced size of the liver leads to of the remaining liver cells.
