Question restatement: The name of the hormone that helps to maintain the level of calcium in the blood is:

Options: 1) parathormone 2) thyroxine 3) insulin 4) aldosterone

Option 1: parathormone. This is the classic name for parathyroid hormone (PTH), which is the primary regulator of calcium homeostasis in the blood. It raises blood calcium levels by promoting calcium release from bones, increasing calcium reabsorption in the kidneys, and enhancing activation of vitamin D to increase intestinal calcium absorption. These combined actions help maintain calcium balance in the plasma.

Option 2: thyroxine. Thyroxine (T4) is a thyroid hormone primarily involved in regulating metabolic rate, growth, and development. It does not play a direct, primary role in maintaining blood calcium levels, so this option does not fit the question’s focus.

Option 3: insulin. Insulin is produced by the pancreas and primarily governs glucose metabolism and blood sugar regulation. While metabolic processes are interconnected, insulin does not function as the main regulator of calcium homeostasis, making this choice incorrect for the given question.

Option 4: aldosterone. Aldosterone is a mineralocorticoid produced by the adrenal cortex that helps regulate sodium and potassium balance and, consequently, blood pressure. Its primary targets are the kidneys for electrolyte handling, not calcium homeostasis, so it does not serve as the main calcium regulator.

Overall, the hormone associated with maintaining blood calcium levels is parathormone, via its actions on bones, kidneys, and vitamin D activation.
