Document Summary
Vitamin d can be obtained through the sun or through our diet. Only one vegetable can produce vitamin d naturally. There are 206 bones in our body. Bones are the structural portion of our body. Our bmd is at its peak at the age of 25 and then will decrease. Bones are remodeled every 2 to 6 months. Calcium is removed and enters other parts of the body. In osteoporosis osteoclasts realize that there is less calcium in the body so it will remove calcium from the bone and add it to the blood plasma. Bigger pores in the bone and density of the bone is less compared to a normal bone. Due to a rapid decline in estrogen levels. Estrogen inhibits calcium absorption, preventing bone degradation. Activity 1: what they ate for the day. Consume foods with vitamin d and calcium. Calcium is an essential mineral for bone strength building block for bone.
