The heart is an organ that pumps oxygenated blood through the body by pumping blood through the blood vessels. It’s located directly beneath the lungs, which is an organ that draws oxygenated air in through the pulmonary artery to the lungs. It’s also responsible for pumping waste materials from the body, such as carbon dioxide and blood to the muscles and other parts of the body. Because it’s so large and moving around quite a bit, it has to be strong and sturdy in order to work properly.
Heart disease is the chief cause of heart failure, or why many people have a defective heart attacks. A defective or failing heart weakens the heart muscles and causes them to work less efficiently. As a result, blood flow is not as well distributed throughout the body. The heart, along with several other organs are affected when this occurs. Heart failure is one of the leading causes of death in the U.S.A.
There are a few types of heart muscle tissue that make up the heart. One is called myocardium, which is found inside the heart. This muscle is used to pump blood from the heart into the various organs. Another type of muscle is called cardiomyocytes, and this is the part of the muscle that actually creates the heartbeat. Finally, there is the contractility of the heart, which is the muscle that keeps the heart muscles pumping – without this necessary muscle function, the heart simply wouldn’t work.
The heart also contains a protein called myoglobin, which absorbs oxygen and removes carbon dioxide. When myoglobin absorbs oxygen, it sends a signal to the lungs for more oxygenated blood to be pumped through the body. The heart has four chambers, or hearts, and they each allow different amounts of blood to be pumped. Two of the chambers are the right and left sides of the heart, while the center is the thickest and allows the blood from the right chambers to travel to the left chamber and the lungs. Blood is pumped through the heart continuously, even while asleep.
The heart consists of many different areas. The largest area of the heart is the coronary arteries, which supply blood and oxygen-rich blood to the heart. Just behind the coronary arteries are the brachial tubes, which transport oxygen-rich blood back to the heart. And at the end of the coronary arteries are the vena cava, which carry oxygen-rich blood back to the lungs.
The reason the heart works so hard and long is that there are so many different parts to it. All the blood flowing to the heart must pass through the coronary arteries first. Then, all oxygen-rich blood has to travel through the various capillaries, and finally it gets to the heart muscle cells. All of these tissues are filled with oxygen and have a great deal to do with how well the heart works. Parts of the heart that are damaged or weakened will decrease its efficiency.
Damage to the coronary arteries can result in the heart failure that is otherwise known as myocardial infarction. This is the most common type of heart attack and death. Other symptoms of the heart attack include breathlessness, swelling of the ankles or legs, sweating, nausea, dizziness and vomiting. In addition, blood clots can form in the aorta, which narrows the arteries and can cause chest pain and abnormal heart rhythms.
While most people experience mild heart problems every day, those who suffer from more severe heart conditions need to be monitored regularly. Anyone who has experienced a heart attack or stroke should get a checkup at least once a year. Anyone who has had to have a bypass surgery should get a heart test at least every six months. Heart conditions can weaken the heart muscle and make it less efficient. As well, they can create a build-up of cholesterol that can clog arteries. The buildup of cholesterol can cause the arteries to narrow, thereby increasing the risk of blood clot occurrences.
