Hormone Regulation of Calcium

The three most common hormones associated with calcium homeostasis.
STUDY
PLAY
Calcitonin stimulus
High blood calcium level
Calcitonin source
Thyroid gland (parafollicular glands)
Calcitonin target tissues
Bone, kidney, intestine
Calcitonin actions
Inhibition of osteoclast activity (decreased bone resorption)
Increased excretion of calcium in kidney
Inhibition of calcium absorption in intestine
Calcitonin goal
Decrease blood calcium level
Parathyroid hormone (PTH) stimulus
Low blood calcium level
Parathyroid hormone (PTH) source
Parathyroid gland
Parathyroid hormone (PTH) target tissues
Bone, kidney, intestine
Parathyroid hormone (PTH) actions
Stimulates osteoclast activity (increased bone resorption)
Decrease excretion of calcium in kidney
Stimulates calcium absorption in intestine
Promotes calcitriol (Vit. D) action
Parathyroid hormone (PTH) goal
Increase blood calcium level
Calcitriol (Active form of Vitamin D) stimulus
Low blood calcium level
Organ in which calcitriol is made
Kidney
Calcitriol actions
Stimulates osteoclast activity (increased bone resorption)
Decrease excretion of calcium in kidney
Stimulates calcium absorption in intestine
Calcitriol goal
Increase blood calcium level
Effectors that stimulate calcitriol production
PTH, low blood calcium
