Final answer:
The tissues involved in this process are nervous tissue and muscle tissue. The nervous tissue sends signals to the muscle tissue, causing it to contract. The muscle tissue in question is the cardiac muscle tissue, which is found only in the heart.
Step-by-step explanation:
The tissues involved in this process are nervous tissue and muscle tissue. The nervous tissue sends signals to the muscle tissue, causing it to contract. The muscle tissue in question is the cardiac muscle tissue, which is found only in the heart. The contraction of the cardiac muscle allows the heart to pump and circulate blood throughout the body.
