Which gland stores hormone in intercellular space before its secretion into blood?

Options

A. Pancreas
B. Thyroid
C. Testis
D. Thyroid

Answer

**Step-by-Step Solution:**

1. **Identify the Glands Listed**: The question provides four options: Pancreas, Thyroid, Testis, and Thyroid (listed twice).

2. **Understand the Function of Each Gland**:
- **Pancreas**: This is a mixed gland that produces both hormones (like insulin) and digestive enzymes. It does not primarily store hormones in intercellular space.
- **Thyroid**: This gland is known for producing hormones such as thyroxine (T4) and triiodothyronine (T3). It is unique among endocrine glands because it stores these hormones in large quantities before releasing them into the bloodstream.
- **Testis**: This is primarily a reproductive organ that produces male sex hormones (like testosterone) but does not store hormones in the same way as the thyroid.

3. **Focus on the Storage Capability**: The question specifically asks for the gland that stores hormones in intercellular space before secretion. The thyroid gland has a specific structure called colloid, where it stores its hormones.

4. **Conclude with the Correct Answer**: Based on the functions and storage capabilities of the glands discussed, the correct answer is the **Thyroid gland**.

**Final Answer**: The gland that stores hormones in intercellular space before their secretion into the blood is the **Thyroid gland**.
