PPT-What are the respiratory structures promote ventilation and gas exchange Monday March

Chapter 22 content not on Wednesday lecture test Goals Describe the airway divisions that lead air to the alveoli where most gas exchange actually occurs Describe the structure and anatomy of the lower airway anatomy as it applies to health and disease. to Long Term .

Pulmonary ventilation. = exchange of gases between lungs and atmosphere.. 2. External respiration. = exchange of gases between alveoli and pulmonary capillaries.. 3. Internal respiration. = exchange of gases between systemic capillaries and tissue cells.. BACKGROUND-Cellular Respiration. Oxygen . is used by cells. Oxygen is needed to convert glucose to ATP. Carbon dioxide is a waste product. Body cells die if respiration fails. FUNCTIONS. Supplies . body with oxygen and removes carbon dioxide.
