Question

The cells that acquire Ca2+ and PO42- from the blood to produce hydroxyapatite that is deposited into the matrix to form mineralized tissue are:

A) Osteoblasts

B) Osteocytes

C) Osteoclasts

Answer 1

Osteoblasts acquire Ca2+ and PO42- from the blood to produce hydroxyapatite that is deposited into the matrix and form mineralized tissue.

Step-by-step explanation:

Osteoblasts are the cells that acquire Ca2+ and PO42- from the blood to produce hydroxyapatite that is deposited into the matrix to form mineralized tissue. When osteoblasts secrete collagen and non-collagen proteins to form the organic matrix, the matrix becomes insoluble and calcium and phosphate deposition occurs. As mineralization proceeds, the osteoblasts become surrounded by bone tissue and differentiate into osteocytes.
