Determination of Calcium Ions in Milk Using Titration

The mineral that is the most plentiful in the body is calcium. It is mainly found in bones and teeth but also in plasma and other fluids within the body. Calcium plays an important role in blood clotting, nerve transmission, muscle contraction and relaxation, cell membrane permeability and the activation of certain enzymes, along with protecting against colorectal cancer. The intake of calcium or dairy products is associated with lower blood pressures, controlling body weight and obesity.

The bones are made up of two minerals, including calcium. Calcium is critical in order to maintain the level of bone mass to support structures of the body. If calcium is truncated in other regions of the body then it will be released from the bones into the bloodstream sending it to the appropriate destination. Bones begin to weaken if an insufficient amount of calcium is not consumed. The body will discontinue absorbing calcium if an abundant amount of calcium is consumed, in which vitamin D aids this process.

(Campbell, 2016). Two giants in childhood lead poisoning research and advocacy, Dr. Philip Landrigan and Dr. David Bellinger, summarize the adverse effects of lead very completely, yet succinctly: “Lead is a devastating poison. It damages children’s brains, erodes intelligence, diminishes creativity and the ability to weigh consequences and make good decisions, impairs language skills, shortens attention span, and predisposes to hyperactive and aggressive behavior. Lead exposure in early childhood is linked to later increased risk for dyslexia and school failure.”(p. 3).

Calcium plays a very significant role in our bodies. Approximately 99 percent of the calcium in our bodies is stored in the teeth and bones. Calcium generates about two percent of our total body weight. Calcium is crucial in bone formation, keeping strong bones and teeth and is known for helping to prevent osteoporosis. Although calcium is mostly thought about in the bones and teeth, it also plays important roles throughout the body. The amount of calcium outside the bones and teeth may be small in comparison to what is inside the bones and teeth, but is very useful in many functions in the body. Calcium is required in functions such as the contraction

The second mineral that interested me was calcium. Calcium is the most abundant mineral in the body (Page. 385). In fact, proper calcium intake is very important. Calcium plays an important role in maintaining proper bone health, dental health, the prevention of colon cancer, and the reduction of obesity. The recommended (UL) for someone my age, and sex is 2500 mg a day (Page. 386). On day 1 of my 3 day analysis I consumed 374.54 mg of calcium. On day 2 I consumed 310.96 mg, and on day 3 I consumed 793.46 mg of calcium. Consequently, I did not meet the recommended (Ul) for calcium

Another component of bone and teeth is phosphorous and calcium, with calcium being required for blood clotting along with aiding in the contraction of muscles.

(which can cause lead poisoning), as well as airborne mold and dust particles from the decay

Calcium is a mineral that is regulated in the blood by the thyroid. According to the Medline Plus website (2018), Calcium is important for balancing a body’s pH, contracting and relaxing muscles, building strong bones, blood clotting, sending and receiving nerve signals, and keeping a normal heartbeat (Medline Plus, 2018). When our diets lack in calcium, our body has to work twice as hard and takes from calcium stores in our bones. As stated in option three, a food journal was kept to keep track of my calcium intake for two days and compared to a USDA website. These are my findings.

Insufficient calcium supply/intake: Each day, we lose calcium through our skin, sweat, urine and faeces, however, the body cannot produce calcium to replace it. A lack of calcium in bone impedes the process of bone restoration that must occur in order to replace lost bone tissue. A constant supply of calcium is required by the blood, so if calcium levels are insufficient, it will leech from the bones into the blood where it is required.

1. It is essential for muscle contraction, but also essential to the structure and health of bones. Bones are continually remodeling and reforming and calcium is a vital part of this process. Without calcium bones can become very thin.

Calcium supports the skeletal structure and its functions by conserving and sustaining the strength of bones and teeth. It is involved in other body processes such as muscle contraction, blood clot formation, nerve impulse transmission, cell metabolism, and assistance in maintaining a healthy blood pressure and immune system. Adult humans absorb approximately 1/3 of the calcium from food. A higher rate of absorption, 50-65%, can be observed amongst newborn infants, children, and pregnant women. Calcium is an essential nutrient and requires vitamin D to be absorbed. Vitamin D is also involved in the regulation of calcium homeostas is. When vitamin D is lacking, the intestine absorbs only 10-15% of the calcium in foods; with the vitamin, intestinal absorption of dietary calcium increases to 30-80%. Once calcium enters the body, it is absorbed throughout the length of the intestines, with the greatest amount of absorption

Hamilton (2011) proposed that Vitamin D appears to be a potentially limiting factor in athletes and leads to deficiency during training. Studies show that levels of 20-30ng/ml 25 OH-Vitamin D is an insufficient amount of Calcium for athletes that have gone through training and levels below 20 and 10ng/ml represents deficiency and severe deficiency (Hamilton 2011). Calcium or Vitamin D deficiencies may have significant long term health effects and have been known to lead to: bowel and colonic cancer, arthritis, diabetes, and cardiovascular disease in some athletes. The biggest health risk associated with this is the increase amount of stress fractures and muscle atrophy problems. Vitamin D is directly proportional,

Throughout life the skeletal system is constantly changing. Bone modeling, formation and growth of bones, occurs from birth to early adulthood resulting in increase in skeletal mass and changes in skeletal form. Naturally the peak bone mass is achieved in the third decade of life, meaning the bones are at their strongest state in human development. Bone remodeling, a response to micro trauma and stress on the bone, is a dynamic process that also occurs through life. Bone is composed of collagen type 1, a protein, minerals such as calcium and phosphate and bone forming cells (osteoblasts and osteocytes) as wells as bone resorbing cells known as osteoclasts. Calcium is a main contributor of bone strength. In fact 99% of calcium is stored in bones and teeth with one percent remaining in the blood. The process of bone remodeling is activated by stressors such as weight bearing and is necessary to maintain bone mass in an adult. It’s a dynamic process in which bone resorption is always

The group 2 metal makes up 4.1% of the Earth’s crust, making it the fifth most abundant metal, and it can only be found in compounds, such as calcium carbonate, calcium sulphate and calcium fluoride (Royal Society of Chemistry). In the body, calcium exists as calcium phosphate to provide

The calcium salts of bone represent a valuable mineral reserve that maintains normal concentrations of calcium and phosphate ions in body fluids. In addition, fat cells within marrow cavities store lipids that represent an important energy reserve. The bones of the skeleton function as levers that direct and modify the forces generated by skeletal muscles. The movements produced range from the delicate motion of a fingertip to powerful changes in the position of the entire body.
