Across
- 3. made of multiple tissue types that work together to perform a function (ex: heart, stomach).
- 9. The relationship between the surface area of an object and its volume. Smaller organisms have a higher ratio, allowing faster exchange of materials like oxygen and nutrients.
- 11. Breaks down food and absorbs nutrients.
- 15. Moves blood, oxygen, nutrients, and wastes through the body.
- 18. Similar structures in different species that come from a common ancestor (ex: human arm and whale flipper).
- 19. Includes skin, hair, and nails; protects the body.
- 20. Protects the body from pathogens and disease.
- 21. Responsible for movement
- 22. Supports, protects, and connects other tissues
Down
- 1. Tissue that sends and receives signals throughout the body
- 2. Produces hormones that regulate body processes.
- 4. Allows breathing and gas exchange (oxygen and carbon dioxide).
- 5. Removes metabolic wastes and maintains fluid balance.
- 6. Structures that have similar functions but evolved independently (ex: bird wings and insect wings).
- 7. Produces offspring.
- 8. Controls body activities and sends signals.
- 10. Allows movement and maintains posture.
- 12. Tissue that covers body surfaces, lines organs, and forms glands
- 13. The study of how body parts function and work together.
- 14. Groups of organs that work together to perform major body functions
- 16. The study of the structure of body parts and how they are organized.
- 17. Provides structure, protects organs, and produces blood cells.
