The main type of muscle tissue is cardiac muscle.
The correct answer is "cardiac."
To find the answer to this question, we can use the process of elimination.
First, let's look at the options:
- Skin: This is not a type of muscle tissue. Skin is actually a type of organ tissue.
- Blood vessels: Again, not a type of muscle tissue. Blood vessels are a type of connective tissue.
- Cardiac: This is the correct answer. Cardiac muscle tissue is the type of muscle tissue that makes up the heart.
- Spongy bone: This is not a type of muscle tissue. Spongy bone is a type of bone tissue.
Therefore, the correct answer is "cardiac."
