                                      The Basic Plan

Materials       Anatomy: Reference text, Human Torso model, Anatomical charts of body
                Physiology: Stopwatch, Clinical thermometer (sterilized), 70 % alcohol

Objectives:
   To apply the terms of reference to parts of the human body
   To identify the major body cavities
   To name the body systems and explain the function of each

Procedures: Before studying the anatomy and physiology of the human body, it is necessary to
understand that the body is an assembly of many parts organized to function as a whole. To
identify a specific part of the body requires knowledge of anatomical terms. In turn, defining
relationships between the different body parts or between a part of the body and a system or
function can be done more clearly.

Anatomy
  A. To recognize the planes of orientation and bodily direction based on the anatomical
     position, locate the various planes and directions the images below using the following
     list of terms. Place the term next to the proper reference position.

           Sagittal plane                 Midsagittal plane               Superior
           Transverse plane               Anterior                        Inferior
           Coronal plane                  Posterior




            Label body cavities and
            indicate where ventral
            and dorsal sides.

 B. Remove all of the organs from the human torso model. Identify each of the cavities. Observe
    the position, size, shape, and specific features of each organ in the list below. Replace all the
    parts within the torso at the end of the exercise. Complete the chart and questions afterwards.
             Appendix                         Kidney                              Spleen
             Brain                            Liver                               Stomach
             Bronchi                          Lungs                               Spinal cord
             Colon                            Ovaries                             Trachea
             Esophagus                        Pancreas                            Urinary bladder
             Gallbladder                      Rectum                              Uterus
             Heart                            Small intestine

       1. What muscle separates the thoracic cavity from the abdominal cavity? ____________
       2. What term applies to all the organs in the abdominal and pelvic cavities? __________
       3. What do we call the symmetry that is typical of all vertebrates? _________________
       4. List the organs found in each body cavity below:

B. Determining Recovery Time – How do your body systems work together to maintain
   homeostasis? How long does it take your body to recover from exercise?
      a. Predictions: Which measurement will have the shortest recovery time? __________
                       Which measurement will have the longest recovery time? __________
      b. At Rest – have your partner sit and rest for 3 minutes. After 3 minutes, take your
          partner’s temperature, pulse, and respiration rate. Follow the guidelines below:
               i. Temperature – use a sterilized clinical thermometer. Shake the mercury down,
                  place the thermometer under your partner’s tongue, and leave it there for 2
                  minutes. Make sure the mouth is closed. (Warn partner not to bite down.)
              ii. Pulse – while you are taking temperature, use a stopwatch and count the number
                  or pulse beats in 30 seconds. Double the number and record.
             iii. Respiratory rate – Count the number of times your partner inhales for 30
                  seconds, double the number, and record.
      c. After Exercise – have your partner exercise rigorously for 2 minutes. Record the time as
          soon as they stop and take your partner’s temp, pulse, and respiration rate as instructed
          above. Record all data.
                                  At Rest               After Exercise              Difference
      Temperature
        Pulse Rate
     Respiratory Rate

      d. Monitoring Recovery Time – keep taking temp, pulse, and respiration rate every minute
          until each variable reaches its resting level. Record the time for each variable. The
          recovery period is the time difference between the completion of the exercise and return
          to resting levels. Compute and record these measurements.
                              Time on Clock           Time on Clock When             Difference
                            Exercised Finished        Returned to Normal         (Recovery Period)
      Temperature
        Pulse Rate
     Respiratory Rate

       e. Analysis – answer the following questions.
             i. Compare your predictions to your results.


              ii. Compare your partner’s results to other groups. Were the results consistent
                  among all the groups? Brainstorm with other students and list three variables that
                  might explain any differences.
                      1. .

                      2. .

                      3. .

              iii. Did any subject’s temperature drop below normal after the exercise? How can
                   you explain this variation if any?
