What is osteoporosis and what are three things an individual can do to avoid osteoporosis later in life, include diet and types of exercise.
Weegy: Osteoporosis, which literally means "porous bone", is a disease in which the density and quality of bone are reduced. As the bones become more porous and fragile, the risk of fracture is greatly increased. [ The loss of bone occurs "silently" and progressively. Often there are no symptoms until the first fracture occurs. The most common fractures associated with osteoporosis occur at the hip, spine and wrist. The incidence of these fractures, particularly at the hip and spine, increases with age in both women and men. The prevention of osteoporosis begins with optimal bone growth and development in youth. Bones are living tissue, and the skeleton grows continually from birth to the end of the teen years, reaching a maximum strength and size (peak bone mass) in early adulthood, around the mid-20s. Bone mass acquired during youth is an important determinant of the risk of osteoporotic fracture during later life. The higher the peak bone mass, the lower the risk of osteoporosis. Once peak bone mass has been reached, it is maintained by a process called "remodeling” – a continuous process in which old bone is removed (resorption) and new bone is created (formation). The renewal of bone is responsible for bone strength throughout life. During childhood and the beginning of adulthood, bone formation is more important than bone resorption. In later life, however, the rate of bone resorption is greater than the rate of bone formation and results in net bone loss. Any factor which causes a higher rate of bone remodelling will ultimately lead to a more rapid loss of bone mass and thus more fragile bones. The nutritional and lifestyle criteria for building strong bones in youth is also applicable to adults to prevent excessive bone loss: ] (More)

Describe three roles of calcium in the human body
Weegy: Calcium (Ca2+) plays a pivotal role in the physiology and biochemistry of organisms and the cell. [ It plays an important role in signal transduction pathways, where it acts as a second messenger, in neurotransmitter release from neurons, contraction of all muscle cell types, and fertilization. Many enzymes require calcium ions as a cofactor, those of the blood-clotting cascade being notable examples. Extracellular calcium is also important for maintaining the potential difference across excitable cell membranes, as well as proper bone formation. Calcium levels in mammals are tightly regulated, with bone acting as the major mineral storage site. Calcium ions, Ca2+, are released from bone into the bloodstream under controlled conditions. Calcium is transported through the bloodstream as dissolved ions or bound to proteins such as serum albumin. Parathyroid hormone secreted by the parathyroid gland regulates the resorption of Ca2+ from bone, reabsorption in the kidney back into circulation, and increases in the activation of vitamin D3 to Calcitriol. Calcitriol, the active form of vitamin D3, promotes absorption of calcium from the intestines and the mobilization of calcium ions from bone matrix. Calcitonin secreted from the parafollicular cells of the thyroid gland also affects calcium levels by opposing parathyroid hormone; however, its physiological significance in humans is dubious. Calcium storages are intracellular organelles, that constantly accumulate Ca2+ ions and release them during certain cellular events. Intracellular Ca2+ storages include mitochondria and the endoplasmic reticulum. ] (More)
