1. How your body generate Energy
Through process of Cellular respiration
Two ingredients (Oxygen and nutrients from food) require in order to produce energy

2. Cellular Respiration require 2 system to support
Respiration system
Blood Circulating System

3. Respiration Syatem
Lungs use the pumping action of the Heart to make our Body Respiration occur
Artery carries oxygenated blood to cell for cellular respiration

4. Respiration system
4. Oxygen burn up in cellular respiration and produce CO2
Vein collects blood carries CO2 and delivers to Lungs for gaseous exchange

5. Blood Circulation
Human circulation originates from the Hearts pumping the blood action.

6. Body Circulation
Blood carries oxygen and nutrients from the lungs, then enters the left chamber of Heart
Through the Artery oxygen is delivered to every single cell in human body

7. Body Circulation
Veins collect Blood which carries Carbon Dioxide and other waste to the right chamber of the Heart
Carbon Dioxide is pumped to the lungs for oxygen exchange

8. How your body generate Energy
Through the 2 systems, Cells are able to generate energy for our daily need
