To answer our unit essential question--How do living things heal?--Place the following steps of healing in the correct order.

• Nutrients move from the blood into cells that will use them by crossing the cell membrane

• Injury damages or destroys cells in the body

• Swelling occurs as blood flow increases at the injury site-bringing extra nutrients

• Existing cells at the site use the nutrients to help them go through mitosis--to make new cells

• The new cells created by mitosis eventually fill in the gap at the injured site
