Document Summary
Hydrogen binds to hb which gets rid of the h ion and bicarbonate is exchanged for chloride ( all these things happen at the same time) this is our gas exchange. Co2 and in order to keep this going we handle bicarbonate. Lung: low co2 and this drives reaction from right to left. 62 whatever is in alveolus it"s the same in the artery. 63 hyperventilation hypoventilation keep the set point by increasing breathing rate because we have to maintain arterial and carbon dioxide. Rythmic breathing inspiration is initiated by contraction of diaphragm and intercostal muscles. Nervous connection here respiratory system is unique voluntary and involuntary control. Involuntary control is mediated by brainstem: pons and medulla. 65 response in total minute ventilation (what goes in and out) vs oxygen concentration. Increase oxygen not much affect and it doesn"t do any much more goof physiologically.
