What is the special about the heart muscle? How often does it work?
Answers
Answer:
Blood carries oxygen and other important nutrients that all body organs need to stay healthy and to work properly. Your heart is a muscle, and its job is to pump blood throughout your circulatory system
On average, it beats around 75 times a minute. As the heart beats, it provides pressure so blood can flow to deliver oxygen and important nutrients to tissue all over your body through an extensive network of arteries, and it has return blood flow through a network of veins.
Explanation:
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.
