Bone resorption - Wikipedia
Bone resorption is resorption of bone tissue, that is, the process by which osteoclasts break down the tissue in bones [1] and release the minerals, resulting in a transfer of calcium from bone tissue to the blood.

2023年8月14日 · PTH acts on the kidneys to increase calcium reabsorption in the ascending loop of Henle, the distal convoluted tubule, and the collecting duct. The kidney also responds to PTH by increasing secretion of Vitamin D3, which in turn stimulates calcium absorption through the gut.
Dietary Reference Intakes for Calcium and Vitamin D.
The skeleton is the principal depot for calcium, containing 98 percent of total body calcium. It can be called on repeatedly, through the processes of bone formation and resorption (referred to as remodeling, as discussed below), to maintain circulating levels of calcium at a constant level.

2023年3月17日 · This process of skeletal change is known as bone remodeling, which both protects the structural integrity of the skeletal system and metabolically contributes to the body's balance of calcium and phosphorus.
6.5A: Bone and Calcium Homeostasis - Medicine LibreTexts
Calcium release from bone is regulated by parathyroid hormone. Calcitriol regulates the levels of calcium and phosphorus in the blood and helps maintain a healthy skeletal system. Bone resorption by osteoclasts releases calcium into the bloodstream, which …
6.7 Calcium Homeostasis: Interactions of the Skeletal System …
PTH promotes reabsorption of calcium from the urine by the kidneys, so that the calcium returns to the blood. Finally, PTH stimulates the synthesis of vitamin D, which in turn, stimulates calcium absorption from any digested food in the small intestine.
Calcitonin and Bone Physiology: In Vitro, In Vivo, and Clinical ...
Abstract. Calcitonin was discovered as a peptide hormone that was known to reduce the calcium levels in the systemic circulation. This hypocalcemic effect is produced due to multiple reasons such as inhibition of bone resorption or suppression of calcium release from the bone.
Calcium intake, calcium homeostasis and health - ScienceDirect
2016年3月1日 · Here, we reviewed the key mechanisms of calcium homeostasis, including calcium sensing receptor regulation, intestinal calcium absorption, renal calcium reabsorption and bone calcium resorption. We further discussed the roles of dietary calcium and vitamin D in diseases associated with dysfunctional regulation of calcium.
The Role of Calcium in Inflammation-Associated Bone Resorption
Understanding the effects of liberation of calcium and its possible effect on burn injury survival may offer us clues as to why inflammatory bone resorption occurs. Specifically, burn injury results in the destruction of the skin barrier to entry of microorganisms into the bloodstream.
Physiology of Calcium Homeostasis - Endocrinology and …
Renal calcium reabsorption occurs via paracellular and transcellular pathways similar to the reabsorption in the intestine. Most filtered calcium is reabsorbed in the proximal tubule (about 60%–70%) and in the TAL (about 15%–20%) mainly by paracellular transport.
