As a means of preventing risks or worsening of certain heart disease, sufferers and their loved ones are encouraged to get themselves educated with how the human heart basically functions. This would help them determine the essential nutrients to be observed when choosing foods for the heart and it would also enable them observe proper movements or exercises intended to achieve a healthier heart.
The heart is one of the most important organs in the human body because it holds the key function to the circulation of blood throughout the body. It is part of the circulatory system, alongside the blood vessels that connect the heart to various organs in the body such as lungs, brain, and stomach. The three main types of blood vessels are the arteries, veins, and capillaries; the arteries are those that carry oxygenated blood to the heart, the veins transport the blood from the heart to other organs of the body, and the capillaries basically serve as connective vessels in smaller organs. All these blood vessels are essential in both pulmonary and systematic circulation processes in the human body. Other than oxygen, hormones are also transported with the blood in order to promote body development and help in other processes involving the rest of the organs. This explains why the heart consequently malfunctions once there is something wrong with the blood vessels.
Meanwhile, the heart is a hollow muscular organ that pumps and propels blood to and from the other organs of the body. Its pumps are normally performed at a beat that ranges from 60 to 100 times every minute. With its complex structure, the heart has the ability to determine which of which must the blood be transported to. It is also capable of adjusting its performance based on the body’s activities. For example: when you sleep, your heart adjusts and slows down its beating; but when you are in an intense motion such as running, your heart will keep up and beat faster. That’s why it is very important for each person to be aware of his own heart’s status in whatever he does; especially does that involve fast heartbeat.
Inside the muscular walls of the heart are four chambers, namely the right atrium, the left atrium, the right ventricle, and the left ventricle. The atria are divided by the interatrial septum, while the ventricles are interventricular septum. The triscupid and mitral valves (collectively known as atrioventricular valves), on the other hand, separate the atria from the ventricles and the two other valves, the pulmonary and aortic valves are those that make division among the pulmonary section of the circulatory system. These walls must be kept healthy as well in order to sustain optimum performance of the heart.
After knowing enough about the human heart and the rest of the circulatory system, it is also of great help to know a thing or two about proper execution of the life-saving aid known as cardiopulmonary resuscitation or CPR. Citywide CPR offers excellent CPR training programs. Check out their official website to get to know more of the CPT training options they offer.
