What body organs should be evaluated for their impact on serum
calcium levels?
Solutions
Expert Solution
The body organs that should be evaluated for such a situation
include -
‘Hypothalamus and Parathyroid gland - The hypothalamus guards
the function of parathyroid gland and release of parathormone and
calcitonin which regulates the level of the serum calcium
levels.
Renal system - Kidney is the organ of excretion. It is
responsible for the excretion of all the solutes and solvents in
the human blood. Calcium is also excreted similarly. Vitamin D
levels should be assessed.
Gastrointestinal tract - Complete evaluation of GIT should be
done for checking the absorption and excretion of the calcium ions
in the gastrointestinal tract from food and into the faeces. It
should include the assessment of each and every organ starting from
the main tract including the accessory organs.
Bone density should be tested as bones are the store house of
calcium and phosphate. Also the matrix in the bones and al out all
the components are made of calcium and phosphates.
1. Why would the body closely regulate blood calcium levels?
Your answer should include four reasons.
2. Explain the role of the hormone calcitonin.
Include the following in your response.
• What triggers the hormone
• The source of the hormone, where does it come from
• The specific action(s) of the hormone
• When is this hormone most active, what part of the lifecycle
and why is this?
If blood calcium
levels started to rise out of homeostatic range, the body would try
to correct this by:
a. Releasing which
hormone?
b. From where is this hormone released?
c. This hormone targets the bones. It causes which cell type to
become more active (compared to another cell type).
d. At the bones, altering the activity of the above cell type
results in an increase or decrease (choose
one) in storage of calcium into the bone matrix?

1.What is the function of calcium in the body? Why is it so hard
for us to absorb? Give me some good food sources and why other
countries don’t rely on milk for their calcium.
2.et’s focus on vitamin and mineral supplements to start. Why do
we need them or do we?
Calcium and vitamin D. Vitamin D is needed for the body to use
calcium. An experiment is designed to study the effects of calcium
and vitamin D supplements on the bones of first-year college
students. The outcome measure is the total body bone mineral
content (TBBMC), a measure of bone health. Three doses of calcium
will be used: 0, 250, and 500 milligrams per day (mg/day). The
doses of vitamin D will be 0, 75, and 150 international units (IU)...
