Which endocrine organs are responsible for regulating blood calcium levels?
Solutions
Expert Solution
The following endocrine organs balance and work in coordination inorder to regulate calcium levels in blood:
PARATHYROID GLANDS: It realeases a hormone called Parathormone(PTH).It increases blood calcium levels by following ways-
- By increasing the activity of osteoclasts in bones.This leads to bone demineralization and release of calcium from bones into blood.
- By increasing reabsorption of calcium from intestines
- By reabsorption of calcium from kidneys
THYROID GLANDS: They secrete a hormone called calcitonin from parafollicular cells.It works opposite to PTH in following manner-
- It decreases the osteoclasts activity helps in bone formation.
- It increases excretion of calcium from urine.
CALCITRIOL: It is the active form of vitamin D,formed in kidneys. It has following effects-
- It increases absorption of calcium from intestines
- It causes remineralization of bones by transferring calcium from blood to bones.

Diabetes is a metabolic disorder in regulating blood glucose
levels and results in hyperglycemia. Inulin and glucagon are two
important hormones secreted by the pancreas to control our blood
glucose level.
Write a short essay discussing:
the role of inulin and glucagon in blood glucose
homeostasis;
the development of diabetes by applying the concept of
homeostatic disorder.

If blood calcium levels drop, the parathyroid gland releases the
hormone called ____________ . This hormone has multiple
effects.
(1) The hormone stimulates bone cells to break down bone tissue
and ____________ calcium ion into the
blood.
(2) The hormone stimulates
the ____________ to conserve calcium ions,
preventing their excretion, and to activate
vitamin ____________ which increases calcium
uptake from the diet.
(3) The hormone increases
the ____________ of calcium from the
intestines.
The result of the these hormonal effects is
to ____________ blood calcium levels.

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?
e. Name...

why when blood calcium levels fall, we remove calcium from the
bone matrix?Why do we sacrifice bone density to maintain blood
calcium? Why is calcium necessary for muscle function and neural
communication?

4) Blood calcium levels are measured in mg/dL. In a group of
patients over 30 you find the following: μ = 9.3 mg/dL, and σ =

a) Give the blood calcium values for the middle 50% of
patients.
(Hint/comment: if you want the middle 50%, how many percent go
in each tail?)
b) Give the blood calcium values for the middle 70% of patients.
c) Give the 85th percentile.
d) Are you surprised by the answers to (b)...

you chose is restored to normal blood levels. List the 5 components
of the cycle in order, like this:

Proper blood calcium levels are required for muscle contraction,
nerve function, and other critical activities in the body. How does
the body maintain homeostasis in response to decreased blood
calcium levels? Discuss the main gland, hormone, and target of the
hormone.
