This process is regulated by PTH, vitamin D, and calcitonin.Д¬ells of the parathyroid gland have plasma membrane receptors for calcium. The bones act as a storage site for calcium: The body deposits calcium in the bones when blood levels get too high, and it releases calcium when blood levels drop too low. The only way it can enter the body is through the diet. Figure 6.7.1 вЂ“ Pathways in Calcium Homeostasis: The body regulates calcium homeostasis with two pathways one is signaled to turn on when blood calcium levels drop below normal and one is the pathway that is signaled to turn on when blood calcium levels are elevated.Д¬alcium is a chemical element that cannot be produced by any biological processes. These body systems work together to maintain a normal calcium level in the blood ( Figure 6.7.1). The skeletal, endocrine, and digestive systems play a role in this, but the kidneys do, too. Obviously, calcium homeostasis is critical. Treatments vary according to the cause, but prognoses are generally good.Д¬onversely, in hypercalcemia, a condition characterized by abnormally high levels of calcium, the nervous system is underactive, which results in lethargy, sluggish reflexes, constipation and loss of appetite, confusion, and in severe cases, coma. The causes of hypocalcemia can range from hormonal imbalances to an improper diet. Without adequate calcium, blood has difficulty coagulating, the heart may skip beats or stop beating altogether, muscles may have difficulty contracting, nerves may have difficulty functioning, and bones may become brittle. Hypocalcemia, a condition characterized by abnormally low levels of calcium, can have an adverse effect on a number of different body systems including circulation, muscles, nerves, and bone. When the body cannot maintain this level, a person will experience hypo- or hypercalcemia. The normal level of calcium in the blood is about 10 mg/dL. Calcium ions are needed not only for bone mineralization but for tooth health, regulation of the heart rate and strength of contraction, blood coagulation, contraction of smooth and skeletal muscle cells, and regulation of nerve impulse conduction. Explain the process of calcium homeostasisД¬alcium is not only the most abundant mineral in bone, it is also the most abundant mineral in the human body.Describe the effect of too much or too little calcium on the body.By the end of this section, you will be able to:
