This is useful because it means that

more carbon dioxide can be dissociated

more oxygen is displaced from the haemoglobin

less oxygen is displaced from the haemoglobin

more carbon dioxide can be taken in by the cells

At the highest partial pressures of oxygen, the saturation of oxygen slows down because

the haemoglobin becomes saturated

the haemoglobin becomes denatured

the haemoglobin is too cold

the oxygen is displaced by carbon dioxide

this is useful because

fetus' use the Bohr Shift

fetus' use a lot of carbon dioxde

fetus' require more oxygen

partial pressure in the placenta is lower than normal
