Document Summary
Metabolic diseases related to calcium and/or phosphorous and/or vitamin d. 2 help regulate blood calcium levels and binding protein. Produced by the thyroid and is released in response to high calcium levels. When blood calcium levels get too low. Decrease calcium excretion by kidney decrease bone calcium reabsorption. Can be a storage depot for calcium and phosphorous. Only occurs in young growing individuals due to deficiency of calcium, phosphorous, and magnesium. After growth maximized epiphysis closes and long bone growth no longer occurs. Absolute deficiency of calcium and or phosphorous and or vitamin d. Occurs in mature animals after cessation of long bone growth. Occurs as a result of calcium requirement for milk production. Chronic loss of calcium into milk depletes the ability to maintain a proper blood calcium level. Arteries not contracting, blood pressure goes down. Milk ejection hard due to lack of contractions. All 3 types of muscle are effect. First smooth muscle, then skeletal muscle, then cardiac.
