Answer 3

70%

Question 4

What will an increase in blood partial oxygen pressure result?

Answer 4

An increase in bound oxygen.

Question 5

Factors that shift the oxygen- hemoglobin curve to the right and downward, causing more oxygen to be released from the hemoglobin?

Answer 5

a decrease in pH, and increase in carbon dioxide, an increase in BPG, and an increase in temperature.

Question 6

What occurs when there is an increase in blood carbon dioxide causing oxygen to be displaced from hemoglobin.

Answer 6

Bohr effects…. Shifts oxygen-hemoglobin dissociation curve to right.

Question 7
