Question

Direction: Refer the given graph and select the correct options
Which of these is correct regarding D, E and F areas in the graph?

• A. D shows venous blood during exercise
• B. E shows normal venous blood
• C. F shows normal arterial blood
• D. All of these

Answer 1

Answer: (D)

All of these

The oxygen-hemoglobin dissociation curve also called the oxyhemoglobin dissociation curve or oxygen dissociation curve (ODC). is a curve that plots the proportion of hemoglobin in its saturated (oxygen-laden) form on the vertical axis against the prevailing oxygen tension on the horizontal axis.

Here, D shows venous blood during exercise, E shows normal venous blood and F shows normal arterial blood.

So, option D is the correct option.
