bone disease. The disease makes bones abnormally porous bone and compressible. Osteoporosis also makes bones weak and fragile. The porous bones resemble sponges‚ and the damage can cause serious injuries. Healthy bones have collagen‚ protein and calcium. They are also constantly being broken and replaced. When new bones are created at a slow rate‚ osteoporosis occurs. The disease usually affects the wrists‚ hips and forearm. Osteoporosis can be present without any prior symptoms. Simple actions can

When carbon dioxide (Co2) is removed from limestone‚ coral‚ seashells‚ or chalk they become lime. This product is easily accessible‚ because an abundance of limestone in found in the crust of the earth‚ and the Co2 is removed simply by heating the limestone. See formula below: 500-600

“Electrolytes turn on all thought and motion‚ almost like a wall switch. They trigger all events like muscle action by controlling ion channels”(Edward Kane‚ 2010).Electrolytes have four minerals that include Sodium‚ (Na) Potassium‚ (K)‚ Magnesium (Mg)‚ and Calcium (Ca). Electrolytes help us by giving us an electrically-charge. Our brain uses it‚ so that they can send messages to others parts of our body so it can continue its function. And that’s very important because without it our nervous system‚ heart

CHAPTER 1 INTRODUCTION 1.1 INTRODUCTION Calcium is the largest mineral in the human body‚ where it plays an important role in absorption and the releasing of calcium in the body is through the intestinal and kidney. The calcium in the body is controlled by hormones and vitamins (Takano et al). The three major components that involve in the controller the calcium is parathyroid hormone (PTH)‚ calcitonin and Vitamin D.

The calcium sulfate can crumble and be washed away (Cristol 2002). Particles which can be formed from sulfate and nitrate ions can affect respiration (Cristol 2002). Acid rain may remove soil nutrients such as calcium and magnesium from soils (Cristol 2002). It robs the soil of essential nutrients and releases aluminum in the soil‚ which

Calcium is one of the most abundant element in the earth’s crust at number 5. Calcium has a very high chemical reactivity so it is never found as an uncombined state in nature. It is a silvery-white metal and it is in the alkaline earth family. Calcium is needed for blood clotting and controlling cell responses in nerves and muscles.Ninety-nine percent of the calcium in the human body is in our bones and teeth. Bone tissues are renewing themselves constantly and to do that they have to build new
