Myocardium

The myocardium is the muscle of the heart that is responsible for its contraction and relaxation. It consists of several layers, each of which performs its own function. The first layer, the endocardium, forms the inner surface of the heart and protects it from damage. The second layer - the myocardium - is the main tissue of the heart and is responsible for the contraction and relaxation of the ventricles and atria. The third layer, the epicardium, covers the outer surface of the heart and provides protection from external influences.

The myocardium consists of muscle fibers that contract under the influence of electrical impulses coming from the sinus node. These impulses spread throughout the myocardium, causing the heart to contract. As the heart contracts, it pumps blood from the ventricles to the arteries and then back to the lungs to take in oxygen and release carbon dioxide.

However, if the myocardium is damaged or does not function properly, it can lead to serious heart conditions such as myocardial infarction or heart failure. Therefore, it is important to monitor your heart health and undergo regular medical examinations.

Good afternoon, dear readers!

Today I would like to talk to you about such an important organ as the myocardium. In the article you can learn a lot of interesting and new things about him.

So, what is myocardium? The myocardium is the muscle tissue of the heart. Thanks to it, the organ contracts and then relaxes, which ensures consistent blood pumping
