Bone remodeling is critical in maintaining?
Osteoclasts which break down existing bone matrix and osteoblasts which lay down new bone matrix in areas that are under the greatest stress such as gravity or where muscles pull on bones.
Cells that free calcium from bone to maintain blood calcium levels are called?
osteoblasts
When does bone remodeling take place?
Bone remodeling begins in embryonic development
Does bone remodeling affect both compact bone tissue and spongy bone tissue?
Bone Remodeling does not affect compact bobe, but it DOES affect Spongy bone tissue.
A function of the skeletal system is to act as a storage area for calcium true or false?
True, blood calcium is very tightly regulated there are two types of bone cells that will either take up excess calcium if blood levels get too high or break down bone to release calcium if blood levels get to low. Both of these bone cells are controlled by the endocrine system in the body.

What percentage of bone calcium is exchanged each year during remodeling?
3 to 5 percent
Cells that free calcium from bone to maintain blood calcium levels are called?
osteoblasts
Ninety-nine percent of this nutrient is stored within the body in bone and becomes available to other tissues when the bone is broken down during remodeling?
Calcium
How does bone marrow regulate homeostasis?
Remodeling or bone turnover is the process of resorption followed by replacement of bone with little change in shape and occurs throughout a person's life. Osteoblasts and osteoclasts, coupled together via paracrine cell signalling, are referred to as bone remodeling units. The purpose of remodeling is to regulate calcium homeostasis, repair micro-damaged bones (from everyday stress) but also to shape and sculpture the skeleton during growth. == The process of bone resorption by the osteoclasts releases stored calcium into the systemic circulation and is an important process in regulating calcium balance. As bone formation actively fixes circulating calcium in its mineral form, removing it from the bloodstream, resorption actively unfixes it thereby increasing circulating calcium levels. These processes occur in tandem at site-specific locations. == Repeated stress, such as weight-bearing exercise or bone healing, results in the bone thickening at the points of maximum stress (Wolff's law). It has been hypothesized that this is a result of bone's piezoelectric properties, which cause bone to generate small electrical potentials under stress
When does bone remodeling take place?
Bone remodeling begins in embryonic development
What control bone remodeling?
Mechanical stress and hormones control bone remodeling.
When a person's diet is too low in calcium the blood levels of calcium will remain constant because the body will get calcium from the?
bone
When a person's diet is too low in calcium the blood levels of calcium will remain constant because the body will get calcium from?
bone
What is the function of parathyroid hormone?
PTH is secreted by the parathyroid glands (which are attached to your thyroid) and acts on bone (via increased bone resorption) , the kidneys (via increased reabsorption of calcium) and the intestine (increased calcium absorption by increased levels of activated vitamin D) to increase blood calcium levels.
What two hormones play a role in bone remodeling and blood calcium level?
I would imagine you are talking about breaking down and building up of bone. Osteoclasts, and osteoblasts. Two types of cells that are constantly breaking down and rebuilding bone. Osteoclasts break down the bone acidically. While osteoblasts rebuild bone, by secreting osteoid, that becomes mineralized.
When a person body is too low in calcium the blood levels of calcium remain constant because the body gets calcium from the?
bone
