Andrew has lived his whole life in San Diego, CA at sea level. One summer in college he gets a job as a field biologist in the Colorado Rockies (elevation
7500 ft. above sea level). The first week he is in Colorado he experiences altitude sickness from the change in atmosphere. Altitude sickness is
characterized by fatigue and shortness of breath as a result of the thinner air which contains less oxygen.
a. How does Andrew's fatigue and shortness of breath relate to the cellular respiration pathway?
be.
b. What would you expect to find if you test the level of lactic acid in Andrew's blood? Explain your answer.

C. A couple weeks later, Andrew is feeling better but he noticed that his appetite has increased. Explain why this might be.
Make notes
1. Which is the major chemical that controls normal breathing?
2. What central nervous-system neurons produce increased depth but decrease
frequency breathing in a person during voluntary action?
3. How do the blood pH and the CO2 change during heavy exercise?
4. Describe the neural factors involved in increasing ventilation during exercise.
5. Why is high oxygen therapy for chronic pulmonary conditions not
recommended?
6. How does the chemoreceptor produce a release of "neurotransmitter" onto
the afferent nerve that inputs to the respiratory center?

Draw a Volume vs Time graph that shows a healthy person taking a deep breath and holding it while submerged underwater. Include three normal breaths, and both the inhale and exhale of the deep breath. 3. Draw a Volume vs Time graph that shows a healthy person who wishes to inhale as much helium as possible from a balloon. Include three normal breaths, and include the exhale and inhale. Label the following volumes: TV, ERV, IRV, and VC.arrow_forwardThe respiratory system. provides body tissues with oxygen provides body tissues with oxygen and carbon dioxide establishes how many breaths are taken per minute provides the body with carbon dioxidearrow_forwardWhich is the order of airflow during inhalation? nasal cavity, trachea, larynx, bronchi, bronchioles, alveoli nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli nasal cavity, larynx, trachea, bronchioles, bronchi, alveoli nasal cavity, trachea, larynx, bronchioles, bronchi, alveoliarrow_forward
- How would paralysis of the diaphragm alter inspiration? It would prevent contraction of the intercostal muscles It would prevent inhalation because the intrapleural pressure would not change It would decrease the intrapleural pressure and allow more air to enter the lungs It would slow expiration because the lung would not relax.arrow_forward1.) What was your recorded resting breathing rate (sitting position)? 2.) What was your breathing rate after exercise? 3.) How would you differentiate your breathing rates before and after exercising? 4.) When do you breath faster? Why do you think you breath faster during more vigorous activities? 5.) Other than exercise, what other factors do you think influence breath/ minute? Why?arrow_forward1. Respiration/Breathing = gas exchange 2. What process uses up oxygen and produces carbon dioxide in the tissues. Answer: Cellular respiration 3. Know the terms: alveoli, pharynx, larynx, trachea, bronchus (bronchi), bronchiole, diaphragm, hemoglobin, myoglobin, partial pressure 4. Function of respiratory system, function of cilia and mucus in the respiratory passageways 5. List the air passageways of the human respiratory system from nostril to alveoli? 6. Where in the respiratory system does the actual gas exchange happen? 7. How is the diaphragm and intercostal muscles involved in breathing? 8. By what process do gases (O2 and CO.) move from alveolar air space into the blood and from blood into the interstitial fluids? Ans: Diffusion 9.

Gas Transport (p. 347-348; Fig. 14.10) a. 97% of oxygen entering the capillaries in the lungs will be transported to tissue cells in the red blood cells. How is the last 2 -3% of bound oxygen carried to tissue cells? i. When oxygen binds to hemoglobin in the lungs, the hemoglobin changes shape and the name changes to This O₂- blood travels throughout the body supplying oxygen to our tissue cells. to ii. At the tissue cells, oxygen diffuses from concentration from the systemic capillaries into the ECF and then into the tissue cells. Now the blood in the system capillaries have (high or low) oxygen concentrations. This causes the hemoglobin the red blood cells to change shape again and its name changes from oxyhemoglobin to This O₂ -- to pick up more blood is now on its way to the oxygen. b. Approximately. % of CO₂ that enters the systemic capillaries from the tissue cells, will travel as a dissolved gas in the blood.…arrow_forward

Use the following terms: oral cavity/nasal cavity, trachea, bronchi, bronchioles, alveoli What gases are being exchanged as we inhale? How do the lungs get rid of all the CO2 they've picked up from the blood? Why do the cells in our body need oxygen? Be specific. How do you think your breathing and lungs adapt when you're exercising?arrow_forward. With regard to how mountain climbers adapt to the low oxygen pressure of higher altitudes, explain the following: (a) Why do 2,3-BPG levels increase by two folds during mountain climbing? (b) Why do you suppose the hemoglobin level differs between people living on low and high altitudes?arrow_forward
