SHORT ANSWER SHEET
26 pts
Name
Be sure to write your name on this sheet and complete the questions. Then separate it from the test, fold it in half
lengthwise and fill in the first three letters of your last name in the blanks provided on the outside of this sheet.
Insert your computer form, with last name letters uppermost into this folded sheet. Then submit these items with
your test questions when you are finished.
A. 2 pts. Which water soluble mineral is required for healthy red blood cells and the making
of the oxygen carrying molecule called hemoglobin?
B. 2 pts. Which fat soluble vitamin (plentiful in carrots) does your body need for good night vision?
C. 6 pts. Vladamir eats approximately 3000 kilocalories of food every day. His total fat intake (at 4.0
kcal/g) is 500 grams per day. Calculate the number of kilocalories of fat that Vladamir eats per day and
then determine the percentage of fat in his total daily kilocalorie intake. Finally, comment on whether
Vladamir is under, meeting, or exceeding the RDA for fats. Show all the steps in your calculations,
writing down all intermediate products or sums in order to receive full credit.

Number of kilocalories of fat that Vladamir eats/day:

E. 6 pts. In the circulatory system diagram to the right
name the one part of the heart and the two blood vessels
indicated by pointer arrows and fill in the blanks with
these names.
F. 6 pts. On the lines below, name all the structures
that a blood cell would pass through beginning in the
vena cava and going through both circuits to end up again
in the vena cava. You don't have to name any of the
valves. Put arrows between each structure in your answers
below to show the direction of blood flow. Include the
specific names for the vessels going into or out of the
heart. You can designate the capillary beds in the lungs
and tissues simply as "lungs" and "tissues"
