Question

Select all that are true of calcitonin. helps decrease blood calcium more effective in children than adults inhibits osteoclast activity signals the kidneys to decrease the loss of calcium in the urine

Answer 1

The answer is;

helps decrease blood calcium

inhibits osteoclast activity

Osteoblast activity is inhibited so that calcium resorption from the bone is repressed. Calcitonin also signals the kidneys to reduce the reabsorption of calcium ions from urine hence increase its loss from the blood.

Answer 2

1. helps decrease blood calcium

2. more effective in children than adults

3. inhibits osteoclast activity

Step-by-step explanation:

Calcitonin is the hormone secreted in response to increased blood calcium level. It serves to reduce the blood calcium level by inhibition of osteoclasts to prevent bone resorption. Calcitonin also reduces the blood calcium level by increasing the loss of calcium into the urine.

The hormone calcitonin suppresses the tubular reabsorption of calcium in kidneys and allows more calcium to be excreted into the urine. The activity of this hormone is more in children to inhibit bone resorption.
