Question

multiple choice question

which of the following cells breaks down bone when the body needs more calcium in the blood?

hematopoiesis
ossification
osteoblasts
osteoclasts

Explanation:

Identify the function of bone cells

Using the Osteoclasts Function and Bone Cells knowledge points

• Osteoclasts are large, multinucleated cells responsible for bone resorption (breaking down bone matrix).
• This breakdown releases stored calcium into the bloodstream to maintain calcium homeostasis.

Analyze the incorrect options

Using the Bone Cells knowledge point

• Hematopoiesis is the process of blood cell formation, not a cell type.
• Ossification is the process of bone formation, not a cell type.
• Osteoblasts are cells that build bone matrix, rather than breaking it down.

Answer:

• Hematopoiesis
• Ossification
• Osteoblasts
• Osteoclasts (Correct answer)
