Cells and Systems Review

2. uses strong magnetic fields that create detailed images of soft tissue (organs, muscles, ligaments).
3. vessels tunnels made of cells that transport blood throughout the body
5. a fluid in the blood that is 92% water and 7% food particles and 1% vitamins and electrolytes.
10. a tool that uses a combination of lenses for making small objects magnified.
13. Blood Cells a cell in blood that carries oxygen from the lungs to the rest of the body.
15. a cell that carries electrical signals to and from the brain helping us interact with our environment.
16. the basic structural, functional, and living piece of all animals.
17. Blood Cells a cell in blood that fights off disease and infection.
18. layered cells that work together to allow the body to move and support the body.
20. an object's job or what it does.
21. Division (Mitosis) when a cell makes a copy of its DNA and splits into two separate cells each cell has a copy of DNA.

1. tiny single-celled microorganisms often found in pond water.
4. carries genetic information in each cell in your body. It makes you who you are.
5. pieces of cells that help clot blood and form scabs.
6. many thin layers of cells that include skin, fat, blood vessels and nerves forming the outer covering of the body of a person.
7. a type of radiation that goes through soft tissue and creates images of hard tissue (bone).
8. a fluid that carries oxygen and nutrients throughout the body.
9. the movement of small molecules (water and oxygen) across the cell membrane.
11. the way an object is designed.
12. a tight pattern of cells that are strong and sturdy and make up the skeletal system.
14. a partial crack in the bone that is not a full break.
19. Membrane the barrier that allows the movement of molecules into and out of the cell.
