How does the heart work?
Heart is a large muscle that works continuously and draws blood throughout the body through muscle contractions. Like the central mechanism of a large machine, the heart problem can affect the function of almost every part of the body. Understanding how this amazing part of the body works can help provide insight into the amazing capabilities of muscle machines.
The heart is primarily divided into four chambers: the upper part has the left and right atrial, while the lower is divided into the left and right ventricles. The right hall and the chamber usually take care of only one particular organ and do most of their work with the lungs. On the other hand, the left side of the organ is responsible for drawing blood to the entire rest of the body.
The heart uses the heart for blood distribution is called the circulatory system. It is a network of pipes that stretch throughout the body as a road system, provides various ramps, shimmemps and exchange to move blood. The circulation system is divided into blood vessels such as capillaries and arteries, toTherés transfer blood to organs and tissues and venules and lives that take blood back to the heart. Along with the lungs and heart, this net creates one of the most important functions of the body: blood circulation.
Not only is the heart responsible for getting the blood where it goes, but also plays an important role in supplying blood by nutrients and oxygen for organs, just like sending someone to school with a charged lunch. On the right side of the organ, blood depressed by oxygen enters with two large veins and the right chamber is pushed into the lungs. After being charged with oxygen in the lungs, now oxygenated blood flows into the left side of the heart and is sent to the rest of the body through the aorta, which is the largest blood vessel in the body.
Many people do not realize that their hearts are actually electrical organs. In order to "beat" the heart, which creates a pumping movement that moves through the blood around, an electrical impulse must be sent to the muscle. This impulse is to createCapped cells in the right atrium, known as a sinotrial node. Disruption of the function of this area can result in an irregular heart rhythm that sometimes leads people to have an artificial electronic device known as a pacemaker, installed to regulate the heart rhythm.
