Why do you think these individuals require different amounts of calcium? (Think about the body and bone health throughout the life cycle.)

Vitamin D is important for bone development and maintenance because vitamin D ________.   A stimulates cells in the small intestine to absorb calcium   B is the part of the bone matrix that gives bone itÕs hardness   C is required for the osteocytes to convert sodium into calcium   D allows the skin to produce calcium when sunlight is present   E is necessary for calcium synthesis by the bone marrow

Select ONE result of how bone development in children and bone maintenance in older adults is affected by diet and describe its characteristics and cause.

How does Parathyroid Hormone elevate blood calcium levels? by increasing the amount of CA2+ removed from the blood by the kidneys by decreasing the amount of CA2+ absorbed from the gut into the blood by increasing the number and activity of osteoclasts by increasing the number and activity of osteoblasts

In young and growing people, the osteoclasts become more active than osteoblasts resulting in gradual decrease in bone. False true

Discuss the stress-strain relationship on bone. In your discussion, include a graph of the stress-strain curve.

What will happen if you do not consume enough calcium on a particular day? If an injury occurs, the blood will not appropriately clot.   Blood calcium levels will drop.   Nerve signaling will stop, so the heart cannot beat. Blood calcium levels will remain in the normal range because calcium is released from the bone to the blood.

normal bone formation and growth are dependent on the adequate intake of:   choice a:  sodium, potassium and vitamin E choice b: potassium, phos. and vitamin d.
