Question

define Cardiac muscle​

Answer 1

Answer:

Cardiac muscle tissue is one of the three types of muscle tissue in your body. The other two types are skeletal muscle tissue and smooth muscle tissue. Cardiac muscle tissue is only found in your heart, where it performs coordinated contractions that allow your heart to pump blood through your circulatory system. Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control. It does this through specialized cells called pacemaker cells. These control the contractions of your heart. Your nervous system sends signals to pacemaker cells that prompt them to either speed up or slow down your heart rate.

Answer 2

Answer:

Cardiac muscle is striated muscle that is present only in the heart.

Explanation:

These muscles make up the heart and allow it to pump blood by contracting and relaxing. These are also called involuntary muscles.
