Answer

To answer the question regarding the embryo of Taenia when it comes out from the intestine of man, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Taenia**: Taenia is a genus of parasitic flatworms (tapeworms) that belong to the phylum Platyhelminthes. They are endoparasites that live in the intestines of their hosts, including humans.

2. **Identify the Type of Larva**: The question specifically asks about the larval stage of Taenia when it exits the human intestine. The larva that is released from the eggs of Taenia is known as Hexacanth.

3. **Hexacanth Larva**: The Hexacanth larva, also referred to as Onchosphere, is the first larval stage that emerges from the egg of Taenia. This larva is characterized by having six hooks, which aids in its attachment to the intestinal wall of the host.

4. **Maturation Process**: After the Hexacanth larva is released, it can develop into Cysticercus larvae, which are encysted forms of the tapeworm. Eventually, these mature into adult Taenia within the intestine.

5. **Conclusion**: Therefore, when the embryo or larva of Taenia comes out from the intestine of man, it is called Hexacanth.

### Final Answer:
The embryo of Taenia when it comes out from the intestine of man is called Hexacanth.
