Knowing a little about the importance of heart health and what our heart actually accomplishes through our body is amazing. Our heart truly is more we realize. Read on to learn a few incredible facts and a little science about how your heart is the key to your overall healthy lifestyle. So many things happen every second inside your body and so much of it starts with your heart. In order to understand what outside life choices make, lets take a moment to connect you with what is going on inside and just how important your heart is to overall body function.
Your heart is truly the ‘heart of your circulatory system’.
The circulatory system enables the movement of nutrients and wastes to and from the cells of our body. It helps in the maintenance of homeostasis. The circulatory system is composed of blood, the blood vessels and the heart. Heart is actually an involuntary muscle which pumps blood through the arteries and veins thus facilitating blood circulation.
How does the Heart Work?
If you imagine the heart to be a pump, the blood vessels are the pipelines laid out all over the body. This pumping system is responsible for circulating pure blood throughout the body.
After about 21 days following conception, human heart starts beating at a rate, which is nearer to the mother’s heart rate. It is still a mystery how blood circulates in the embryo for the first 21 days when the heart has not formed.
The heart constitutes of four chambers- two atria and two ventricles. Right side of the heart collects deoxygenated blood in the right atrium. The blood flows to the lungs via the right ventricle. In the lungs the blood is oxygenized. The left heart collects the purified blood into the left atrium. From here the blood goes into the left ventricle. The left ventricle is responsible for circulating it to all the body parts.
How does the heart work without ceasing?
From where does it derive its nutrition? Blood that the heart pumps does not supply it with oxygen. Coronary arteries are special blood vessels, which are attached to the heart form outside. They render oxygen and nutrients to the heart. The right coronary artery supplies blood to the right ventricle while the left one services the rest of the heart.
Can you hear your heart beat?
Take a quiet moment right now. Close your eyes and just listen for your heart beat. Can you feel it beating inside your chest? Enjoy the beat and sound of it for a moment.
How does the heart beat?
So many things happen in less than a second inside your body. The sinoatral node in the right atrium of the heart generates an electrical impulse at regular intervals. It causes the atria to contract and pump blood into the ventricles. The impulse reaches the atrioventricular node from where it reaches the ventricles through the atrioventricular bundle. Ventricles contract to pump blood to the arteries. Heart then relaxes for a small period of time after which the beating begins again. The electrical system of the heart makes its beating possible. When at rest, the heart beats at the rate of 70-100 beats per minute. It makes a lub-dub sound with each beat.
Your heart is one of the most wonderful organs of human body. It gives life to every cell of the body by feeding it with oxygenated and nutrition-rich blood. After knowing how the heart works, it is important to provide it with a healthy environment to work in. It’s thus so important to remain healthy and happy. Has ‘working of the heart’ won your hearts? I am sure it has!
