Which of the following function is related with thyroid hormones ?

Options

A. They play an important role in the regulation of BMR
B. They also support RBC formation
C. They control the metabolism of carbohydrates, proteins and fat
D. All

Answer

To determine which functions are related to thyroid hormones, we can analyze the roles of these hormones in the body. Here’s a step-by-step breakdown of the functions associated with thyroid hormones:

### Step 1: Identify the Thyroid Hormones
- The primary hormones produced by the thyroid gland are thyroxine (T4) and triiodothyronine (T3). These hormones are crucial for various metabolic processes in the body.

### Step 2: Understand the Role of Thyroid Hormones
- Thyroid hormones are involved in regulating the basic metabolic rate (BMR), which is the rate at which the body uses energy while at rest. They influence how quickly the body burns calories and utilizes energy.

### Step 3: Explore Other Functions
- Apart from regulating BMR, thyroid hormones also play a role in erythropoiesis, which is the formation of red blood cells (RBCs). This function is vital for maintaining adequate oxygen levels in the blood.

### Step 4: Metabolism Regulation
- Thyroid hormones are essential for the metabolism of carbohydrates, proteins, and fats. They help in the conversion of these macronutrients into energy, thus influencing overall metabolism.

### Step 5: Conclusion
- Based on the functions discussed, we can conclude that thyroid hormones are related to:
1. Regulation of BMR.
2. Support of RBC formation (erythropoiesis).
3. Control of metabolism of carbohydrates, proteins, and fats.

### Final Answer
- Therefore, all the options provided are correct regarding the functions related to thyroid hormones.
