Bone tissue growth and remodeling begins in utero and continues throughout a person's life. Specialized cells called osteoblasts continuously deposit new bone tissue, while other cells called osteoclasts breast down old tissue. The balance between bone growth and reabsorption helps maintain normal bone mass.

Your liver contains thousands of enzymes that carry out chemical reactions required for proper metabolism, digestion and to help detoxify your body. Elevated liver enzymes in your bloodstream indicate the presence of liver damage that causes the enzymes to leach from your liver cells into your bloodstream.
