Cellular Respiration
Digestive, Circulatory, and Respiratory Systems

2. Cellular Respiration
Is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products
Formula
C6H12O O CO H2O + ATP
Glucose +Oxygen Carbon Dioxide + Water + Energy

3. Cellular Respiration and Digestion
Through the digestive system the body acquires the food it needs to fuel all cells .

4. Cellular Respiration and Digestion
Main food source needed are carbohydrates broken into glucose molecules

5. Cellular Respiration and Digestion
The cell breaks the glucose into something smaller and sends it off to the mitochondria there the mitochondria uses these smaller pieces with oxygen to make energy for you

6. Cellular Respiration and Circulatory
The heart and vessels are responsible to pump and transport all nutrients to all parts of the body through tiny vessels called capillaries

7. Cellular Respiration and Circulatory
Things like glucose, oxygen and carbon dioxide are able to enter or exit the tissue or vessel

8. Cellular Respiration and Circulatory
The only way to get glucose (from the intestine) and oxygen (from the lung) to the cells of your toes is through blood vessels

9. Cellular Respiration and Circulatory
The blood vessels are essential in removing waste products too, like carbon dioxide

10. Cellular Respiration and Respiratory
The lungs are necessary to get oxygen into the body
In the lungs there are millions of little air sacs called alveoli that are surrounded by capillaries here the blood drops off carbon dioxide and picks up oxygen

11. Cellular Respiration and Respiratory
This oxygen will be taken directly to the cells when the oxygen gets to the cell
The mitochondria takes it and begins the process of cellular respiration

12. 62% is used as thermal energy to heat organism
How Much Energy
During this process 38% glucose is released as energy to complete life’s process
62% is used as thermal energy to heat organism

14. Dietary Needs For Cells

15. Dietary Needs For Cells
Protein
Essential to Diets
They help rebuild and repair cells

16. Dietary Needs For Cells
Fiber
Keeps the digestive system working properly. Which is essential for cellular respiration

17. Dietary Needs For Cells
Carbohydrates
Essential for cellular respiration to convert to glucose for energy
Grains provide a good source.
