  21. Why does a person with a cold often have a stuffed up nose?
    a. the response of the nasal epithelium to irritants, such as those that cause the common cold, is to secrete greater amounts of mucus than normal to trap the virus particles 
    b. during the time that a person has a cold, air is easier to breathe if it is of much higher humidity than normal, and the presence of the cold viruses stimulates mucus production to increase that humidity 
    c. excess saliva is inhaled through the internal nares when a person sneezes and filled the nasal cavity 
    d. no known reason
    a. the response of the nasal epithelium to irritants, such as those that cause the common cold, is to secrete greater amounts of mucus than normal to trap the virus particles
  22. How does deep breathing differ from costal breathing?
    a. in deep breathing the thoracic volume changes because the rib cage changes shape

    c. the diaphragm contracts in deep breathing while it does not contract in costal breathing 
    d. in deep breathing, muscles contract to assist in both inspiration and expiration
    c. the diaphragm contracts in deep breathing while is does not contract in costal breathing

    a. they can distort more easily to permit urine to move in or out 
    b. the shaped prevents urine backflow toward the ureters when the urinary bladder contracts
    c. the opening is compressed between the middle and lateral umbilical ligaments because these structures support this part of the ureter 
    d. there is no significance; the shape occurs because of the position only
