• Loss of function

• Decreased energy production

What are cells, tissues, and organs?

• Cells are the basic unit of life, tissues are groups of similar cells, and organs are structures made of tissues.

• Cells are structures made of tissues, tissues are the basic unit of life, and organs are groups of similar cells.

• Cells are groups of similar tissues, tissues are structures made of organs, and organs are the basic unit of life.

• Cells are structures made of organs, tissues are groups of similar organs, and organs are the basic unit of life.

What factors influence a cell's response to injury?

• The nature of the stressor and the cell's ability to adapt
