Testes are present in [In case of humans]

Options

A. Alveolar sacs
B. Scrotal sacs
C. Pharyngeal pouches
D. abdominal cavity

Answer

**Step-by-Step Solution:**

1. **Identify the Location of Testes in Humans:**
- The testes are the male reproductive organs responsible for producing sperm and male hormones, particularly testosterone.

2. **Determine the Correct Answer from Given Options:**
- The options provided are: alveolar sac, scrotal sac, pharyngeal pouches, and abdominal cavity.
- The correct location for the testes in humans is the scrotal sac.

3. **Explain the Function of the Scrotal Sac:**
- The scrotal sac, also known as the scrotum, is an external pouch that holds the testes. It is crucial for maintaining the optimal temperature for sperm production, which is lower than the body’s core temperature.

4. **Describe the Structure of the Testes:**
- The testes are oval-shaped organs, typically about the size of an olive. They are paired organs, meaning there are two testes in males.

5. **Discuss the Role of the Testes:**
- The primary functions of the testes include the production of sperm and the secretion of testosterone, which is responsible for male secondary sexual characteristics such as deepening of the voice, hair growth, and muscle development.

6. **Clarify Incorrect Options:**
- The alveolar sac is related to the lungs and gas exchange, the pharyngeal pouches are associated with fish gills, and the abdominal cavity does not house the testes.

**Final Answer:**
The testes are present in the scrotal sac in humans.
