What is The Heart? How Does the Heart Work?

What is The Heart? How Does the Heart Work?

Heart; it is an organ that is located between the chest, under the ribs near the left park and consists of many muscles. It stands closer to the left between the chest line that is not exactly on the left. While the heart weight is around 340 gr in men; weight is slightly lower in women. The part where the heartbeat is heard is called the apex in medicine.

What is The Structure of The Heart?

What is The Structure of The Heart?

The heart performs the task of pumping blood in four different parts. There are chambers made of muscles that push the blood forward when compressed in the sections. Muscle thickness varies according to the circumference of each chamber. The left ventricle wail is the part with the tickets muscle since it is the place where the pumping takes place the most. Blood coming to the heart through veins; it begins to fill the thin walled atria on both sides of the heart. The blood pumped to the ventricles, which have a thick muscle structure, is also pumped to the arteries by the back of the ventricles, and there is also a partition between the atria and the ventricles.

The task of the heart is to send the clean blood it has sent to the body back to the lungs to be cleaned and than send it back to the body. The main function of the heart is to pump blood, so it has a muscular structure. The pulmonary circulation occurs with the blood flowing back and forth to the lungs; Afterwards, it is distributed throughout the body and systemic blood circulation takes place. The blood is carried from the heart to the organs by the arteries and is collected back by the veins.

How Does The Heart’s Timing Develop?

How Does The Heart’s Timing Develop?

Each time the heart experiences a beat, the two atria contract simultaneously and begin pumping blood to the ventricles. It then contracts the ventricles. This happens with an electrical timing system. This situation is also quite complex. The focal point , called the sino atrial node, located on the right atrium at the heart, is the key part that controls the work of the heart. Electrical simulation is emitted from this park, allowing the atrial to contract. There is an atrioventricular node at the junction of the ventricles and atrial. The arrival of the contraction stimulus causes a slight delay in this part, it first spreads to the compartment between the ventricles and then continues in the form contractions.
