What happens to the bones when people grow older?

Answer 1

• The bones lose calcium and also their density.
• Vertebrae become thinner and the spine compresses making the padding between the vertebrae wears away.
• Joints become less flexible

Answer 2

From birth through adolescence, more bone is produced than is lost during bone remodeling. In young adults, the rates of bone production and loss are about the same. As the levels of sex steroids diminish during middle age, especially in women after menopause, a decrease in bone mass occurs because bone destruction outpaces bone formation. Because women's bones generally are smaller than men's bones to begin with, loss of bone mass in old age typically causes greater problems in women. These factors contribute to a higher incidence of osteoporosis in women.

Aging has two main effects on the skeletal system: Bones become more brittle and lose mass. Bone brittleness results from a decrease in the rate of protein synthesis and in the production of human growth hormone, which diminishes the production of the collagen fibers that give bone its strength and flexibility. As a result, inorganic minerals gradually constitute a greater proportion of the bone extracellular matrix. Loss of bone mass results from demineralization and usually begins after age 30 in females, accelerates greatly around age 45 as levels of estrogens decrease, and continues until as much as 30% of the calcium in bones is lost by age 70. Once bone loss begins in females, about 8% of bone mass is lost every 10 years. In males, calcium loss from bone typically does not begin until after age 60, and about 3% of bone mass is lost every 10 years. The loss of calcium from bones is one of the problems in osteoporosis (described in the Common Disorders section). Loss of bone mass also leads to bone deformity, pain, stiffness, some loss of height, and loss of teeth.

Answer 3

After the age of 30 or so, the bones do not absorb calcium, phosphorus and other important nutrients as well as they need to for optimum bone health. More calcium etc, may be absorbed out of the bone into the bloodstream as well, so bones can become brittle and break more easily, which can result in osteoporosis.

Answer 4

• The bones lose calcium and also their density.
• Vertebrae become thinner and the spine compresses making the padding between the vertebrae wears away.
• Joints become less flexible

Answer 5

when you grow the bones in your body grow with you.

For the rest of the answer ask a doctor

obviously your bones are going to grow if they didnt you would still look like a baby but have a deep throat that sounds to me to be quite impossible

Answer 6

They can become weak and brittle leading to bones that break easily with falls or injuries.

Answer 7

while we grow up the bones too grows andat the stage of old it becomes weak and deplition of calcium and some type of diseases occurs.

Answer 8

When people grow older, their bones becomes weaker.

Answer 9

There is typically a depletion of calcium, and bones become more brittle. If broken, they take much longer.
