Body Systems

2. Basic structural and functional unit of a living organism.
4. The amount of blood pumped by the heart per pump.
5. The process in all cells that uses glucose to produce useful energy for cellular processes.
10. The body's ability to take in, transport, and use oxygen to produce energy during sustained physical activities.
11. The process where oxygen is delivered to the blood and waste carbon dioxide moves from the blood to be breathed out.
13. Tiny air sacs in the lungs where gas exchange occurs.
14. The principle that the body gradually loses its fitness adaptations if training stops.
16. Structure made up of a group of tissues working together to perform specific functions.
18. Group of organs with related functions working together to perform body functions.
19. The respiratory and circulatory systems working together to distribute oxygen to cells throughout the body.
20. The system made up of the heart and all blood vessels responsible for pumping blood around the body.

1. Respiration occurring in the cytoplasm when there is not enough oxygen to complete aerobic respiration.
3. Māori knowledge concerned with understanding the natural world both historically and today.
6. A living thing that performs all seven life processes.
7. The process of obtaining energy from food when there is plenty of oxygen available.
8. Group of cells with similar structures working together to perform a shared function.
9. The organelle in the cell where aerobic respiration takes place.
12. Thick blood vessels that pump blood away from the heart.
15. The part of the cell where anaerobic respiration occurs.
17. The process where the body becomes stronger and more efficient after regular training stresses.
