Bones tend to become less dense and more fragile as people grow older. This can lead to conditions like osteoporosis, where bones weaken and become more prone to fractures. It is important to engage in weight-bearing exercises and consume enough calcium and vitamin D to maintain bone health as we age.
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.
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.
No, the number of bones in the human body remains the same as we grow older. A baby is born with about 270 bones, but many of these fuse together as the body matures, resulting in the adult skeleton of around 206 bones.
A newborn baby has around 300 bones.A baby has 300 bones at birth. As they grow older the small bones grow together unil finaly as as an adult there are 206.A baby has about 300 bones at birth. As they grow small bones grow together and as an adult you have 206 bones.
Bones typically break due to a significant force or impact applied to them, exceeding their strength. This can happen from falls, accidents, or injuries. Factors like age, bone health, and underlying medical conditions can also contribute to bone fractures.
At birth, children have around 270 bones. As they grow, some of these bones fuse together, resulting in the adult human skeletal structure of 206 bones.
A baby is usually born with around 270-300 bones, which eventually fuse together as they grow. An adult typically has 206 bones in their body.
bones do not stretch; they grow by building more cells.
your bones will become weak, and can lead to much serious problems like arthritis when we grow older

They die.
as you grow your bones calcium (from eating healthy foods )becomes shorter.it happens by the age of about 50.
the babies bones increase in their size like their body size
Hello, When a human grows, their bones will grow together and combine, that's why you won't have the same number of bones as an adult.
i think it dose grow because your bones grow and your heart is a bone
They are fed and grow bigger and older.
Young people (Children) have the same amount of bones as an adult. All our bones are already grown or in a growing stage at birth. They only develop as we grow. The amount of bones stays the same for a child and an adult.
