Bone remodeling is critical in maintaining?
Bone remodeling is critical in maintaining bone strength and structure by constantly renewing and repairing bone tissue. It helps regulate calcium levels in the body, enables bones to adapt to mechanical stress, and plays a role in healing fractures. Hormones, physical activity, and nutrition all influence the bone remodeling process.
Compare and contrast the role of PTH hormone and mechanical forces acting on the skeleton?
Parathyroid hormone (PTH) regulates calcium levels in the blood by stimulating bone resorption and increasing calcium absorption in the intestines and kidneys. Mechanical forces on the skeleton, such as weight-bearing exercise, help maintain bone strength by promoting bone formation and remodeling. While PTH directly influences calcium regulation, mechanical forces indirectly influence bone health and density through the stimulation of osteoblast activity.
What are bones cells that liquefy bone matrix and release calcium to the blood called?
Bone cells that liquefy the bone matrix and release calcium into the blood are called Osteoclasts. Immature or matrix depositing bone cells are called osteoblasts.
Bone cells that liquefy bone matrix and release calcium to the blood are called?
Osteoclasts are bone cells responsible for breaking down and resorbing bone tissue, releasing calcium and minerals into the bloodstream. They play a crucial role in bone remodeling and maintenance.
What does Osteocytes secrete?
Osteocytes become surrounded by bone matrix and are relatively inactive, but do have the capability to produce components needed to maintain the bone matrix if needed. Lacunae osteoblasts change into osteocytes.

What is the role of the parathyroid gland and it's hormone parathyroid hormone in bone remodeling?
The parathyroid gland produces parathyroid hormone (PTH), which plays a crucial role in bone remodeling by regulating calcium levels in the blood. When calcium levels drop, PTH is released, stimulating the activity of osteoclasts—cells that break down bone tissue to release calcium into the bloodstream. This process helps maintain calcium homeostasis and supports various physiological functions. Additionally, PTH influences the balance between bone formation and resorption, ensuring proper bone health and density.

What is the primary function of osteoclasts?
The primary function of osteoclasts is to break down and resorb bone tissue, allowing for bone remodeling and turnover. They help regulate calcium levels in the body and play a role in bone repair and growth.
What are bones cells that liquefy bone matrix and release calcium to the blood called?
Bone cells that liquefy the bone matrix and release calcium into the blood are called Osteoclasts. Immature or matrix depositing bone cells are called osteoblasts.
What percentage of bone calcium is exchanged each year during remodeling?
3 to 5 percent
HOW is calcium important to the skeletal system?
Calcium is important for bone health because it is a major component of bone tissue, providing strength and structure. It is essential for proper bone mineralization and helps to maintain bone density. Calcium also supports bone remodeling, which is the process of breaking down and rebuilding bone tissue.

What is the name of free calcium from bone to maintain blood calcium levels.?
The process of releasing free calcium from bone to maintain blood calcium levels is called "bone resorption." This occurs primarily through the action of osteoclasts, which break down bone tissue and release calcium into the bloodstream. This mechanism is essential for regulating calcium homeostasis in the body.
Cells that free calcium from bone to maintain blood calcium levels are called?
Osteoclasts are cells responsible for breaking down bone tissue to release calcium into the bloodstream to maintain blood calcium levels.
What three vitamins are closely associated with calcium and phosphorus?
The three vitamins closely associated with calcium and phosphorus are vitamin D, vitamin K, and vitamin A. Vitamin D enhances calcium absorption in the intestines and regulates calcium and phosphorus levels in the bloodstream. Vitamin K plays a crucial role in bone metabolism and helps in the regulation of calcium within the bones and arteries. Vitamin A is important for bone health as it influences the activity of osteoblasts and osteoclasts, which are essential for bone remodeling.
