7 Jul 2020 A network of specialized muscle cells is found in the heart's walls. These muscle cells send signals to the rest of the heart muscle causing a contraction. This group of muscle cells is called the cardiac.
The heart is a pump that performs 72 beats per minute, equivalent to 1.2 Hertz, which each beat lasts around 0.830 ms (milliseconds) to boost the blood circulation that transports and distributes nutrients and oxygen, maintains the balance of fluids and body temperature as well as removes carbon dioxide and other metabolic byproducts from all cells of the body.

Istanbul are affected in different ways, in distinctive phases, and to varying degrees. The contraction phase of the heart is called c. systole. When the ventricles contract, it is called systole, and the blood is pumped out to the lungs (from the right side), and out to the rest of The stages of heart contraction and relaxation can be divided up into 4 parts: ventricular diastole, atrial systole, atrial diastole and ventricular systole. Systole is when the chamber of the heart is contracting, and diastole is when it is relaxing. Put the phases of the cardiac cycle in the correct order, starting after ventricular filling.
