Blood pH Reading Questions

Question #1 You test your pool water to find its pH. The test strip reads that the pH is Is the water in your pool acidic, basic, or neutral? Use evidence from the reading to support your answer. Review Information About pH pH below 7 is acidic pH at 7 is neutral pH above 7 is basic

Question #2 What is the set point for human blood pH? Is this level acidic or basic?

Question #3 A person’s blood pH is found to be Describe if this person’s blood will function properly, using the range for blood pH in your answer.

Question #4 What is the name of the primary molecule involved in blood pH regulation?

Question #5 Describe the effect of carbon dioxide on blood.

Question #6 How does the human body release carbon dioxide from the bloodstream?

Question #7 Fill in the chart for the responses to a change in blood pH. An ______ in carbon dioxide… Causes the blood pH to decrease (becomes acidic)… Which causes _________to increase (breath faster). A _______ in carbon dioxide… Causes the blood pH to increase (becomes too basic)… Which causes breathing rate to ______ (breath slower).

Question #8 Describe how negative feedback is involved in regulating blood pH.

Question #9 Put the following events in the correct order: Billy’s cells undergo cellular respiration. Billy’s breathing rate increases. Billy’s blood pH level returns to its set point! The pH of Billy’s blood is decreased. The CO 2 sensors in Billy’s blood send a message to his brain to tell him that his CO 2 levels are too high. Billy’s brain sends a message to his diaphragm. Billy starts to exercise so he uses energy. Billy exhales CO 2 at a greater rate. Billy gives off CO 2 as a waste product.

Question #10 Complete the chart, listing the organs involved in blood pH homeostasis, the system each organ belongs to and the organs’ function. BloodTransport BrainSends message to cause a change DiaphragmContracts during breathing LungsRemoves CO 2 while exhaling OrganSystemFunction

Question #11 Draw and label the organs on the human body figure.
