Question

The shape of oxygen dissociation curve plotted between % saturation of Hb with O 2 and p O 2 is (A) sigmoid (B) J-shaped (C) exponential, consisting of three phases (D) hyperbolic

Tardigrade Admin · Accepted Answer

Oxygen haemoglobin dissociation curve is sigmoid-shaped.
The relationship between the

p O_{2}

and the per cent saturation of haemoglobin when represented on a graph is termed as oxygen haemoglobin dissociation curve. The

p O_{2}

in the arterial blood is about

95 mm H g

and the per cent saturation of haemoglobin at this partial pressure is

97%

.
