CO2 By Ruby B, Kristen C, Isy M, Sarah T, Angelique T and Daisy Z Respiratory System O2 CO2 Parts of the Respiratory System N2 O2 O2 N2 N2 O2 Inhaled Air: Exhaled Air: CO2 N2 N2 CO2 O2 O2 O2 How Breathing Rate is Controlled How Breathing Rate is Controlled The respiratory control center controls our breathing.
It is located in the Medulla. It keeps us breathing even when we are asleep. A baby's breathing rate is faster than an adult's. The diaphragm is the muscle used for breathing. Chemoreceptors sense the amount of oxygen, carbon dioxide and acid levels in our bodies. The apneustic centre and the pneumotaxic centre Your emotions and many other factors affect your breathing. Function of the ribs and diaphragm in the breathing process The diaphragm expands and contracts as you breathe. When you breathe in, the diaphragm expands
When you breathe out, the diaphragm contracts Ribs are connected to the diaphragm and together they help you breathe. The ribs move in with the diaphragm when you exhale, and out when you inhale. Diaphragmatic breathing helps you take in more air and reach your vital capacity.

Carbon dioxide
Exhalation What happens between the alveoli and the capillaries Capillaries Alveoli act as the primary gas exchange units of the lung. Expired Air Resuscitation 1. 2. Pinch nose 3. 4. 5. If the person is 8 or under, lightly puff. If the person is 9 or over, breathe normally. Cystic Fibrosis Cystic fibrosis is a hereditary disease
Autosomal recessive disorder caused by mutation in the cystic fibrosis trans-membrane conductance regulator gene

This leads to serious lung infections, and other health problems 6. 7. If there is a pulse, continue breathing until they are breathing by themselves. 8. -The End-
