    Chemistry for Physiology
    Which of the following ways of expressing a solution’s concentration is written as a number without units?
    Specific gravity of a solution is the ratio of the density of the solution to the density of water (which is 1.0). Consequently the density units “cancel out”.

    Renal System
    What could be concluded of a person who (during the previous 3 h) has produced a total of 100 ml of urine that is bright yellow and has a strong (but not unpleasant) odour?
    100 ml/3 hr. is a low rate of urine production, indicating dehydration. Hence, the urine will be concentrated as the body is conserving water, and its SG will be high.

    Cardiovascular System
    Say a diastolic blood pressure reading was 80 mm Hg. This is consistent with which one of the following statements?
    Because atmospheric pressure (about 760 mmHg) is always present, it is taken to be a “relative zero”, and other pressures are stated as an amount greater than atmospheric pressure. We say 80 implying 80 more than 760, rather than stating 840 mmHg (760 + 80).
