- Why do you think a person is able to perform anaerobic exercise (such as lifting and holding a heavy weight) only briefly but can sustain aerobic exercise (such as walking or swimming) for long periods? (Hint: Muscles have limited energy stores.)arrow_forwardWhat do you mean by voluntary muscles?arrow_forwardImagine you are an oxygen molecule. Your job is to get inside the body and deliver oxygen to a working muscle. Create a word flowchart to identify all the structures you will encounter during your passage from the outside air to the inside of a muscle cell. Include a short description of how you will exchange places with carbon dioxide when you arrive at the cell.arrow_forward

- A researcher is investigating the composition of muscle tissue in thegastrocnemius muscles (in the calf of the leg) of athletes. She takesa needle biopsy from the muscle and determines the concentration(or enzyme activity) of several substances. Describe the major differences this researcher sees when comparing the muscles of athletes whoperform in the following events: 100-meter dash, weight lifting, and10,000-meter runarrow_forwardExperiments 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.arrow_forwardExperiments were performed in an anatomy and physiology laboratory.
