Question 75 – Blood, the heart, circulation and respiration - Questions

A physiologist investigated the relationship between the partial pressure of oxygen ( $pO_2$ ) in blood plasma and the percentage saturation of hemoglobin with oxygen in a healthy human blood sample.

Seven blood samples were maintained at a constant temperature of 37 °C and a constant physiological carbon dioxide partial pressure ( $pCO_2$ ) of 5.3 kPa. Each sample was exposed to a different partial pressure of oxygen, and the percentage saturation of hemoglobin was recorded.

Table 1: Oxygen partial pressure and hemoglobin saturation

Sample	Partial pressure of oxygen, $pO_2$ (kPa)	Percentage saturation of hemoglobin (%)
A	0	0
B	2	12
C	4	38
D	6	74
E	8	91
F	10	96
G	12	97

Describe the relationship shown by this data.
