The correct Answer is:
To determine which hormone controls blood calcium levels, we can analyze the options provided: 1. **Glucagon**: This hormone is produced by the alpha cells of the pancreas and primarily functions to increase blood glucose levels. It does not play a role in regulating calcium levels. 2. **ACTH (Adrenocorticotropic Hormone)**: This hormone is secreted by the anterior pituitary gland and is responsible for stimulating the adrenal cortex to release cortisol. It does not have a direct effect on blood calcium levels. 3. **Insulin**: Produced by the beta cells of the pancreas, insulin is crucial for regulating blood glucose levels. It does not influence calcium levels in the blood. 4. **Parathormone (Parathyroid Hormone)**: This hormone is secreted by the parathyroid glands and is specifically responsible for regulating calcium levels in the blood. It increases blood calcium levels by promoting the release of calcium from bones, increasing calcium absorption in the intestines, and enhancing calcium reabsorption in the kidneys. Based on the analysis of the options, the hormone that controls blood calcium levels is **Parathormone**. ### Final Answer: **Parathormone (Parathyroid Hormone)** controls blood calcium levels.
