                              2. Metabolic rate
                                1. The speed at which chemical reactions take place in the body.
                                  1. Affected by:
                                    1. Age
                                      1. Inherited factors
                                        1. Muscle:Fat proportion
                                          1. Amount of physical activity
                                      2. Balanced Diet
                                        1. A Balanced Diet contains different food types in the correct amounts
                                          1. If a person eats an unbalanced diet they lack a food type which their body needs, they will suffer Malnutrition
                                            1. We need to eat fruit because it contains essential Vitamins and Minerals ( C,E and A
                                            2. Salt
                                              1. Too much salt leads to: Risk of Stroke, Risk of Heart Attack and Increase of Blood Preasure
                                              2. Respiration
                                                1. Energy allows the body to: Grow, Repair, Keep Warm, Move and Feel
                                                  1. Respiration: Is the transformation of stored chemical energy in food to useful energy to the body
                                                    1. The formula for Respiration is: Glucose + Oxygen = Carbon Dioxide + Water + Energy
                                                      1. Oxygen and Glucose needed for respiration are carried to all the cells in the blood. Glucose and Oxygen are the reactants and the Carbon Dioxide and Water are the products.
                                                  2. Route of the air
                                                    1. Air Passes through the Trachea, Reaches the Alveoli where gas exchange happens, Oxygen enters the blood and it is taken to all the cells of the body, the Carbon Dioxide leaves the blood and is carried to the lungs where it is breathed out
                                                      1. Nose, Trachea, Bronchus, Bronchioles, Alveoli
                                                        1. Gas Exchange happens in the Alveoli
