6. Here is the oxygen-hemoglobin dissociation curve. 4. (3pts) Why does the curve look like an S with flat part at low Po?? Explain this characteristic b. (4pts) What happens to oxygen- hemoglobin dissociation as blood flows from systemic arteries to systemic veins? You can sketch the graph on the Answer Sheet and use it to answer this question more clearly than just with words. c. (4pts) if a person starts exercising, what will happen to this curve? Explain your reasoning. d. (4pts) Also in the case of exercise, what other changes will be happening to this person's cardiovascular and respiratory systems? Be as specific as possible in your explanation - use the material learned in this course, not your general knowledge from before. (For example, just saying \"they will breathe more heavily\" does not earn you any points. You must give physiological explanation in addition.)

The graph shows the oxygen dissociation curve for human haemoglobin. Partial pressure of oxygen (mmHg) Draw another curve on the graph to show the oxygen dissociation curve in a location with a higher concentration of carbon dioxide, for example in an active muscle. Explain why the position of the oxygen dissociation curve for a higher carbon dioxide concentration demonstrates an important adaptation.

The graph shows an oxygen dissociation curve for hemoglobin. Based on the graph, what would likely cause the curve to shift to the left, as shown by the dotted plot line? a. a decrease in carbon dioxide, increase in pH, or a decrease in temperature b. an increase in carbon dioxide, increase in pH, or a decrease in temperature c. a decrease in carbon dioxide, decrease in pH, or a decrease in temperature d. a decrease in carbon dioxide, increase in pH, or an increase in temperature
The graph given shows an axygen dissociation curve for haemoglobin. Where in the body will haemoglobin be saturated at the percentages shown at points 1,2 and 3 on the graph? Left ventricle Pulmonary vein Vena cava (a) 2 3 (b) 2 (c) 2 3 (d) 3 2
