Oxygen
Oxygen
Oxygen releases energy
Oxygen Helps cells break down food for energy (cellular respiration)
Cellular Respiration Produces carbon dioxide as a waste product
Oxygen Gas Exchange -Trade oxygen & carbon dioxide
Oxygen Arteries – carry oxygenated blood Gas exchange in capillaries
Oxygen Review From mouth/nose, to trachea (windpipe) To bronchi, to bronchioles, to alveoli Alveoli – gas exchange, oxygen to blood To heart, to arteries, to capillaries Capillaries – gas exchange, oxygen to cells
Carbon Dioxide Veins – carry carbon dioxide blood
Carbon Dioxide Gas exchange in alveoli -carbon dioxide and oxygen traded
Oxygen Review Carbon Dioxide Review From mouth/nose, to trachea (windpipe) To bronchi, to bronchioles, to alveoli Alveoli – gas exchange, oxygen to blood To heart, to arteries, to capillaries Capillaries – gas exchange, oxygen to cells Carbon Dioxide Review From cells to capillaries (gas exchange) to veins From veins to heart to capillaries to alveoli Alveoli – gas exchange, carbon dioxide to lungs To bronchioles, to bronchi, to trachea Exhaled from mouth/nose
Review Gas Exchange Blood Vessels In alveoli (lungs) In capillaries (between arteries & veins) Blood Vessels Arteries – carry oxygenated blood Veins – carry carbon dioxide blood Capillaries – gas exchange
