A femoral hernia occurs when the intestine enters the canal carrying the femoral artery into the upper thigh. Femoral hernias are most common in women, especially those who are pregnant or obese. In an umbilical hernia, part of the small intestine passes through the abdominal wall near the navel.
Parathyroid hormone is the most important endocrine regulator of calcium and phosphorus concentration in extracellular fluid. This hormone is secreted from cells of the parathyroid glands and finds its major target cells in bone and kidney.
The parathyroid glands maintain adequate levels of blood calcium. A) slowing the activity of tissues that require calcium for activity b) targeting the bone and activating osteoclasts so that calcium will be released c) blocking the action of growth hormone d) antagonizing the synthesis of calcitonin.Follow.t increases blood calcium levels by stimulating osteoclasts to break down bone and release calcium. It also increases gastrointestinal calcium absorption by activating vitamin D, and promotes calcium uptake by the kidneys. Answer = b.
