From the very first time the heart starts pounding until the time of death, it may beat more than 3.5 billion times. The center of the circulatory system is the heart. The average heart beats 100,000 times each day, pushing around 2,000 gallons of blood throughout your body. With a life span of 70-90, the heart will beat two to three billion times and circulate 50-65 million gallons of blood.
The hearts role is to pump oxygenated blood to every cell in the body by having a continuous beat. Throughout time the heart has created mystery, however current technology has solved most of the mystery, there still remains an enchantment and eagerness to learn more.
In this article, we will learn the involvement of the hearts configuration involving how the blood travels through the blood vessels. Learn what you can do to monitor your heart's heath and how to keep it healthy during your lifetime.
The Heart's Anatomy
The weight of the heart is between 7 and 15 ounces and is a little bigger than the size of your fist. The
location of the heart is between the lungs in the center of the chest. The membrane that surrounds the heart is called the pericardium. The heart consists of four chambers. The left and right atria are known as the upper chambers. The lower chambers are referred to as the left and right ventricles. The septum is the wall of muscle that divides the left and right atria and left and right ventricles. The strongest chamber of the heart is the left ventricle.

...heart attack. Heart Disease can refer to an assortment of diseases affecting the heart. A heart attack happens when heart muscle is destroyed or hurt due to not getting enough oxygenated blood to maintain life. Different examples of Heart Disease include Cardiomyopathy, Cardiovascular Disease, Hypertension, and Ischemic Hear Disease.

of the heart: one chamber is on the top and one chamber is on the
The heart is an extraordinary structure that is the base of all human life. However, it similar to the uncomplicated functions of water pumps. As the heart beats, blood is distributed throughout the body using a network of blood vessels. The functions of the heart can be kept in regular and healthy conditions through exercise. Exercise has an effect on the blood that is circulating through the body. That circulating blood makes the heart desire more oxygen, causing the heart rate to increase rapidly to keep up with activity demand.
Heart failure is common condition with many illnesses and condition. Knowing the illnesses and conditions that can cause heart failure will reduce the chance of having heart failure. Treat and control the conditions and illnesses can decrease the occurrence of heart failure even further.
the heart is made of a muscle called the cardiac muscle unlike other muscles in the body the cardiac muscle never gets tiered its constantly working and never stops. It squeezes blood out of the heart and then relaxes it to fill it back with blood again in and this process continues and happens everyday until you are dead. The heart beats non stop this is achieved because of the cardiac Muscle.
The heart is two sided and has four chambers and is mostly made up of muscle. The heart’s muscles are different from other muscles in the body because the heart’s muscles cannot become tired, so the muscle is always expanding and contacting. The heart usually beats between 60 and 100 beats per minute. In the right side of the heart, there is low pressure and its job is to send red blood cells. Blood enters the right heart through a chamber which is called right atrium. The right atrium is another word for entry room. Since the atrium is located above the right ventricle, a mixture of gravity and a squeeze pushes tricuspid valve into the right ventricle. The tricuspid is made up of three things that allow blood to travel from top to bottom in the heart but closes to prevent the blood from backing up in the right atrium.
Twenty years of research has firmly established that periodontal disease and cardiovascular disease are associated. However the exact relationship between the two is still controversial. In order to understand the relationship between periodontal disease and cardiovascular disease people need to understand the physiology, and microbiology behind both of the diseases.
The evolutionary development of the heart has come a long way from the singular tube to the multi-chambered complex ones that now operate in humans. Some scientists proclaim that the genetics over the years have not changed much at all. They also say that the human heart is a perfected machine that has seemed to reach the goal of its evolutionary time. However, the heart will continue to amaze us. With its constant abnormalities, gene mutations, and it’s striving for perfection, the heart will never be completely known and understood. Instead it will be an enigma, constantly dodging our rules and always providing us with life.
For the heart to perform properly, the functions of the left ventricle must also perform properly. It should relax quickly after each contraction so the oxygenated blood stored in the left atrium can fill it quickly. On the other hand, it should also contract quickly and with a lot of force to push this vital blood into the aorta. The force and pressure from the left ventricle has to be strong enough to overcome the aortic pressure so the blood will push forward. The pressure of the left ventricle also needs to be strong enough to stretch the aorta to accommodate sudden increases in blood volume. To maintain the needs of the body, the left ventricle needs to be able to quickly adapt its pumping capacity signaled by the nervous system. For example, the left ventricle should increase its pumping capacity signaled b...
The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...
Heart disease is the leading cause of death worldwide. (social inequality, 2009). Heart disease is a structural or functional abnormality of the heart, or the blood vessel supplying the heart, that impairs its functioning. (free dictionary). Heart disease is also known as cardiovascular disease. Since there are many conditions related with heart disease. The most common types are coronary artery disease or damage in the heart’s major blood vessels, stroke or damage to the brain from interruption of its blood supply, and high blood pressure or a condition in which the force of the blood against the artery walls in too high. These conditions may lead to a heart attack. (mayo).
It is about the size of a person's fist. The heart has four chambers. The upper two chambers are the right artium and left atrium, and the lower two are the right ventricle and left ventricle. Blood is pumped through the chambers, aided by four heart valves. The valves open and close to let the blood flow in only one direction.
The heart is a pump with four chambers made of their own special muscle called cardiac muscle. Its interwoven muscle fibers enable the heart to contract or squeeze together automatically (Colombo 7). It’s about the same size of a fist and weighs some where around two hundred fifty to three hundred fifty grams (Marieb 432). The size of the heart depends on a person’s height and size. The heart wall is enclosed in three layers: superficial epicardium, middle epicardium, and deep epicardium. It is then enclosed in a double-walled sac called the Pericardium. The terms Systole and Diastole refer respectively and literally to the contraction and relaxation periods of heart activity (Marieb 432). While the doctor is taking a patient’s blood pressure, he listens for the contractions and relaxations of the heart. He also listens for them to make sure that they are going in a single rhythm, to make sure that there are no arrhythmias or complications. The heart muscle does not depend on the nervous system. If the nervous s...
As humans we need the heart to pump blood all around the body in order
The heart is crucial to all walks of life and although the heart is approximately the size of a fist, it plays a vital role in life. The heart is broken down into four chambers, four valves, and different arteries and veins along with it. The atrium are located on the upper half of the heart, known as the right and left atria. On the bottom half of the heart, the chambers are known as the right and left ventricles. The atria work together simultaneously and then the ventricles will work in a synchronized manner. The atria will contract and then the ventricles will in tandem. Although it seems simple enough, the heart is one extraordinary organ that has a mind of its own.
