2.36 describe the structure of the thorax, including the ribs, intercostal muscles, diaphragm, trachea, bronchi, bronchioles, alveoli and pleural membranes

2.36 •the thorax is at the top of your body

                  •it’s separated from the lower part of the body by the diaphragm

        

        •the lungs are pink and are protected by the ribcage and are surrounded by pleural membranes, preventing friction against the ribs

        

        •the air that you breathe in goes through the trachea. This splits into two tubes called bronchi, and each bronchus goes to each lung

                  •the bronchi split into smaller tubes called bronchioles

                            •the bronchioles finally end at the alveoli, where the gas exchange takes

place
