Textbook Question
Chapter 4, Problem 1AWK
Your roommate says that the concept of homeostasis is being violated when the rate of respiration goes up during exercise, because the rate of respiration clearly is not being held constant. Explain to him where his thinking is faulty.

Students have asked these similar questions
Experiments were performed in an anatomy and physiology laboratory. First, the rate and depth of respiration for a resting student were determined. In experiment A, students ran in place for 30 seconds, immediately sat down and relaxed, and then had their respiration rate and depth measured.Experiment B was conducted in the same manner as experiment A, except that the students held their breath while running in place. What differences in respiration would you expect for the two experiments? Explain the basis for your predictions.
The oxygen consumed after strenuous exercise stops is significantly greater than the oxygen deficit and is termed excess postexercise oxygen consumption (EPOC). Why is so much more oxygen required after intense exercise?
If the oxygen levels increased throughout your body, you would expect to see the following occur to bring levels back to homeostasis
Group of answer choices
A decrease in sympathetic activity to the smooth muscle of blood vessels
An increase in heart rate
An increase in stroke volume
An increase in parasympathetic activity to the smooth muscle of blood vessels
An increase in sympathetic activity to the heart

- Which of the following statements about oxygen transport is TRUE. Increases in temperature and decreases in pH cause myoglobin to release oxygen to improve delivery to the hemoglobin in muscles. A molecule of myoglobin has higher oxygen binding capacity than a molecule of hemoglobin. Myoglobin has a higher oxygen affinity than does hemoglobin. Fetal hemoglobin has a lower affinity for oxygen than maternal hemoglobin, which makes it better suited to extract oxygen from the maternal circulation.arrow_forwardThe 100 meter dash is a quick and short run requiring explosive speed. On completion of the dash the runners will continue to breathe hard for several seconds to minutes even though they are no longer running. Which of the following is the best explanation for why this is so? a.Slow oxidative fibers are recruited last and have only started to work at completion of the run. b.The runners' fast oxidative muscles are so slow to utilize oxygen it only begins aerobic respiration by the time the run has finished. c.The runners' use of stored oxygen, glucose and creatine phosphate is being replenished and this requires a prolonged increase of oxygen intake. d. Since the exercise was mostly aerobic exercise, the runners' bodies have not yet realizedarrow_forwardThe movement of air out of the lungs during forceful expiration is a result of Air is forced out of the lungs due to the active contraction of the abdominal and external intercostal muscles. Air moves out of the lungs due to the passive relaxing of the diaphragm and intercostal muscles.

- Which of the following describes an example of a negative feedback loop that occurs during exercise? Decreased CO2 levels trigger an increased breathing rate which serves to bring the CO2 levels back down to normal levels None of these options are correct Decreased CO2 levels trigger an decreased breathing rate which serves to bring the CO2 levels back down to normal levels O Increased CO2 levels trigger an increased breathing rate which serves to bring the CO2 levels back down to normal levelsarrow_forwardOne consequence of oxygen deprivation is decreased production of ATP.

At high altitude, a decrease in PC02 of the blood stimulates an increase in ventilation. An increase in the HCO3- concentration in blood stimulates ventilation. A slight decrease in arterial PO2 is a stronger stimulus for increased ventilation than is a comparable decrease in arterial PCO2. The most important signal for regulating ventilation is the H+ concentration of arterial blood. Increased concentrations of lactic acid stimulate ventilation primarily by acting on peripheral chemoreceptors.arrow_forwardDefine the term oxygen deficitarrow_forward
