Cardiac muscle function is an amazing thing to explore. Out of all the muscle types, the cardiac muscle is the most unique and least known of them. Read on to know how this muscle works continuously.
The job our heart does is no mean feat. Thanks to our constant requirement of oxygen, it never gets to rest! But jokes apart, on a serious note, the fact that the human heart functions properly is a reason of us being alive. Our heart, as we all know is composed of chambers, two atria and two ventricles. The atria act as receiving chambers and the ventricles pump out the blood. Now, this 'pumping' action is facilitated by the cardiac muscle. Cardiac muscle is one of the three major types of muscles, including the skeletal muscles and smooth muscles. The contraction of the cells of this muscle in the heart push the blood from the atria and the ventricles till the circulatory system's blood vessels. The cells of this cardiac muscle are like any other, depending on adequate blood supply for supplying oxygen and nutrients and removal of waste products. How does this cardiac muscle function and where is it exactly located in the heart? get to know in the text to come.
