The Calcium in Our Body II
What factors regulate it?
- PTH. PTH is produced in the parathyroid glands and is important to maintain the level of calcium in the blood. Increases the output of calcium from bone, renal tubular reabsorption of calcium and intestinal calcium absorption.
All of this grows the level of calcium in the blood. Thus, their secretion increases with decreasing blood calcium.
- Vitamin D. Vitamin D is obtained from food (oily fish, organ meats, especially brain, fish liver oil, butter and egg yolk, fortified milk and fortified cereals) and also occurs in the skin by the action of the sun from its precursor (7-dehydrocholesterol).
Young people have large deposits of this precursor in the skin but are diminishing with age, so that increased vitamin D in the diet of the elderly. Also the populations of the countries that receive little sun have a diminished capacity to synthesize vitamin D, so that increased vitamin D in food. Vitamin D stimulates intestinal calcium absorption and promotes bone regeneration.
- Calcitonin. is a hormone produced and secreted by special cells in the thyroid. The secretion is stimulated by increased calcium in the blood. Its effect decreases calcium levels in it. This favors the decrease output of calcium from the bones and reduces the loss of calcium by the kidney.
The Calcium in Our Body I
Calcium is a mineral that reaches the blood through diet and mobilization from the bones. A permanent intake through foods rich in calcium, so as to meet nutritional needs, is essential to prevent diseases like osteoporosis.
What is calcium?
Calcium is a mineral found abundantly in nature and is also part of our body. Plays an essential role in bone formation. 99% of the calcium exists in our body is in them.
The remaining 1% is in the blood, extracellular fluid in adipose tissue. Calcium is necessary for the transmission of nerve impulses for muscle contraction, for the clotting of blood and heart function.
If you do not eat enough, the body is forced to remove it from the bones to ensure that 1%. In the metabolism and composition of bones and teeth, calcium is strongly associated with phosphorus (80% of body phosphorus is part of the bones) and magnesium.
The body gets 1% of circulating calcium necessary through two mechanisms:
- Diet: By the intestinal absorption of calcium entering the diet, especially from fortified milk or calcium-rich derivatives.
- Bones: Through the mobilization of calcium from bones.
Bone Health & Physical Activities
Exercise and other sports and physical activities are beneficial to other aspects of their lives. Not only help to lighten up and manage stress but that will improve your flexibility and your sense of balance. Greater flexibility and balance are factors directly related to the prevention of falls and injuries in the event of the fall. It is common that older people experience problems recovering from a fall due to poor bone health because of the lack of training.
The health of your bones is an important factor in overall health. Ensuring drinking the proper amount of calcium daily and exercise your body to strengthen your bones, help to prevent fractures at an older age. Turn now to strengthen your bones will compensate later with a more comfortable old age and free of aches and pains.
Keep Bones Strong & Healthy.
There are a number of exercises you can do to keep bones strong and healthy.
The main group of exercises that help maintain bone health are those related to the strength and resilience of pesos.
Activities such as football, basketball, tennis, baseball, dancing, aerobics, and walking are good exercises for cardiovascular endurance training that can benefit your bone density. Has also been shown that lifting weights helps maintain bone health. The first reason for this kind of exercise benefit your health is because they stimulate bone formation. The bones are related to the movement of the body. Consequently, muscles that are attached to bone, will also be reinforced, giving more support to their bones.
Treatment of A Hip Fracture
Hip fracture is manifested by fracture of the femur, the bone joint responsibility in this area of the body.
It’s an injury that usually occurs in older people, a product of attrition suffered by the passing of the years in which the bone was in an awkward position.
These types of fractures are serious injuries that cause severe pain and which must urgently intervene surgically.
The two types of hip fractures are the most common fracture of the femoral neck and intertrochanteric fracture, where the case of rupture of the neck is more complex for not allowing proper blood flow to the femoral head.
Chocolate And Bones
Mucas is cardioprotective benefits of chocolate have been recognized, however, the findings of a recent Australian research is not good news for the most devoted: Older women who eat chocolate every day, have more fragile bones and a possible increased risk of osteoporosis.

Collarbone
The collarbone (clavicle) is a round bone that connects the scapula to the sternum. At each end is a joint. Between sternum and collarbone about Sterno-claviculaire joint between the sternum and shoulder acromioclavicular joint. Because the joints are moving properly, which also sits in both absorb blows to have a cartilage disc (called a meniscus).
All blood vessels and nerves to the arm below the center of the clavicle by.
What injuries are on the collar for
1. A broken collarbone from a fall occurs on the shoulder or a direct blow. The force of the fall is transmitted through the shoulder on the collar. It is a much voorlomend injury in two particular groups of people: children and athletes. It happens sometimes even during the birth of a baby appears to have been broken collarbone. The collar of a child can easily break the collarbone because only fully cured when you’re 20 years old. Of the athletes you regularly see cyclists.
2. Dislocation of the clavicle – by a fall on the elbow joint acromioclaviculaire may become dislocated. By a direct blow or collision with an opponent, the fancier joints sternoclaviculaire.
3. Meniscus tear of the joints
4. overload or inflammation of the joints
Signs of a fraction
* Drooping shoulder (down and forward)
* Inability to lift the arm because of pain
* An abrasive / grinding feeling when you try to lift your arm
* A swelling and bruising over the site of the fracture
* Although the skin is rarely punctured, a piece of bone is pressing against the skin and thus cause a protrusion Read the rest of this entry »
