cells are found on the side while cones are found on the bottom. 3. Explain how the body maintains homeostasis of serum (blood calcium) levels through the use of the thyroid and parathyroid gland. The body maintains homeostasis of serum levels through the use of the thyroid and parathyroid glands because the thyroid secretes calcitonin and the parathyroid secretes parathyroid hormone. Both of these hormones help regulate blood calcium levels. 4. Explain the role the hypothalamus

significant public health problem in 130 countries and affects 740 million people. An estimated one-third of the world’s population is currently susceptible to the risk of iodine deficiency. Iodine is a vital nutrient for the proper functioning of the thyroid gland‚ which regulates growth and metabolism. Iodine deficiency is the primary cause of preventable learning disabilities and brain damage‚ with it’s most devastating impact on the brain of a developing fetus. Children born to iodine deficient mothers

responsible for maintaining calcium homeostasis in the body. They are the parathyroid hormone‚ vitamin D and calcitonin. Parathyroid is the main hormone involved in regulating calcium levels. There are four parathyroid glands which lie posterior to the thyroid glands. The cells in the parathyroid gland act in response to the calcium levels in the blood. When the calcium levels are low the cells increase the release of the parathyroid hormone. The parathyroid hormone raises blood calcium levels by triggering

The major glands that make up the human endocrine system are the hypothalamus‚ pituitary‚ thyroid‚ parathyroids‚ adrenals‚ pineal body‚ the pancreas‚ and the reproductive glands‚ which include the ovaries and testes. The endocrine system has three basic functions‚ regulate metabolic functions of the body‚ regulate rate of chemical reactions in
