Most of it is bound to hemoglobin while the remainder iscarried in what form?About 23% of the carbon dioxide in blood is carried ________.
What would a rightward shift in the oxygen-hemoglobin binding curve indicate?Choose the combination of factors that would lead to the greatest oxygen unloading from hemoglobin.Which area of the brain stimulates the diaphragm to contract to initiate inspiration?Diffusion rate is directly proportional tosurface area and concentration gradient.O2can be caused by one of two mechanisms. One of them is that the inspired air has a low oxygen content. What is the other reason?What is the main difference between fetal and adult hemoglobin?An increase in the level of carbon dioxide in the blood willincrease the rate of breathing.Which change would cause a leftward shift in the oxygen-hemoglobin binding curve?
