5 True/False Questions
chemical factors of breathing control → Respiratory center located in medulla oblongata (in the brain). Increase in CO2 and decrease in O2 in the blood will trigger respiratory center.
pulmonary venilation → Throat. Common passageway for air and food. 5" long.
alveoli → Composed of single layer of epithelial tissue. Inner surfaces covered with surfactant to keep from collapsing. Each surrounded by capillaries. Oxygen and carbon dioxide exchange takes place between these and capillaries.
respiratory movement → 1 inspiration and 1 expiration= 1 respiration. Normal adult= 14-20 respirations per minute. Increases with exercise, body temperature, and certain diseases. Age (newborn= 40-60 per minute). Sleep= respirations go down. Emotion can bring respirations up or down.
neural factors of breathing control → Respiratory center located in medulla oblongata (in the brain). Increase in CO2 and decrease in O2 in the blood will trigger respiratory center.
