Which of These Is Demonstrated by the Oxygen-Hemoglobin Dissociation Curve

question 70

Multiple Choice

Which of these is demonstrated by the oxygen-hemoglobin dissociation curve?

• A)The greater the PO₂ of the blood,the greater the dissociation of O₂ from hemoglobin.
• B)At normal resting systemic arterial PO₂,hemoglobin is almost 100% saturated with oxygen.
• C)At normal resting systemic venous PO₂,only about 75% of the hemoglobin is in the form of deoxyhemoglobin.
• D)More additional oxygen binds to hemoglobin when going from a PO₂ of 60 to 100 mmHg,than is added when going from a PO₂ of 40 to 60 mmHg.
• E)As PO₂ increases,the saturation of hemoglobin with oxygen increases linearly.

Definitions:

Extreme Values

The maximum and minimum values in a data set, often of particular interest for identifying outliers.

Bell Shaped

A term often used in statistics to describe the symmetrical, bell-like curve of a normal distribution.

Sensitive

Capable of detecting or responding to small changes, often used in the context of measurements, instruments, or systems.

Extreme Values

Data points that are significantly different from the majority of observations in a dataset; they can be unusually high or low.
