Oxygen is carried in the blood in two ways. Most of it is bound to hemoglobin while the remainder is
carried in what form?

What would a rightward shift in the oxygen-hemoglobin binding curve indicate?

hemoglobin.
Which area of the brain stimulates the diaphragm to contract to initiate inspiration?
Diffusion rate is directly proportional to
surface area and concentration gradient.
