Both the right and left atrium contract causing blood to flow though the two valves, and then into the left ventricle. The left ventricle pumps blood into the systemic circulation through the aorta. This systemic circulation system is much bigger than the pulmonary circulation system, which is why the left ventricle is so big. The blood on the left side of the heart is oxygenated. It becomes oxygenated when the deoxygenated blood passes through the right atrium and then flows into the left ventricle. It is then pumped along the pulmonary artery into the lungs where it is oxygenated. It then travels through the pulmonary veins back into the heart. It enters through the left atrium and then travels to the left ventricle. This process is repeated over and over again, to make blood continuously flow through the heart, lungs and body. This process ensures that there is always enough oxygen for the body to work

Inside our body there is a powerful muscular pump, which is known as the one of the main organs in the human body. This hollow, cone shaped, pump lies slightly left within the center of the chest called our heart. The heart is made up of different structures and actions in order for it to work, combined with a network of blood vessels form what we know as the cardiovascular system.

Our cardiovascular system is composed of the heart and blood vessels. The main purpose of this system is to transport substances throughout the body. Even though transportation is the main function of the cardiovascular system, it is not the only function. Along with transportation we have protection and regulation.

The cardiovascular system, however, would not be able to effectively complete these functions without help from what is sometimes referred to as the body’s hardest-working organ- the heart. Approximately the size of a fist, the heart is contains four chambers (the uppermost are called the atria and the lowermost are called the ventricles) and four valves. Additionally, the heart is surrounded by the pericardium, a structure that serves to protect the heart, keep the heart stabilized in the chest, and

The heart is a major organ in the body, this organ pumps blood around the body, through veins, capillaries and arteries. The blood carries oxygen to our cells and also carries waste products which include water and carbon dioxide, which are products of respiration. Blood also helps spread out salts, enzymes, urea, nutrients, hormones and heat across the body.

In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left

*Both sides of the heart are doing this at the same exact time and contracting/relaxing is what pumps the blood from one place to the other.

The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).

The left side of the heart, has the left atrium and ventricle that takes in oxygenated blood from the lungs and pumps it out of the aorta.

The lungs get blood by means of two sets of arteries: pulmonary arteries and bronchial arteries. Deoxygenated blood goes through the pulmonary trunk which separates into a left pulmonary artery that enters the left lung and a right pulmonary artery that enters the right lung. Return of the oxygenated blood to the heart happens by method of the four pulmonary veins which deplete into the left atrium (Tortora and Nielsen, 2012).

The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries (which provide oxygen and nutrients to body tissues by transporting the blood throughout the body). The heart is located in the thoracic cavity medial to the lungs and posterior to the sternum.

The Cardiovascular or Circular system is located in the chest cavity and made up of the heart, arteries, veins, blood vessels (capillaries), four chambers of the heart (right atrium, right ventricle, left atrium and left ventricle) and three layers of heart (epicardium/ pericardium, myocardium and endocardium).The function of the heart is to ensure a steady flow of blood throughout the body, supplying oxygen and nutrients to the cells. The heart pumps deoxygenated blood to the lungs by the pulmonary vein to be oxygenated with the aid of the aorta and distribute the blood to the entire body (Abrahams, 2017).

Located in the middle of your chest slightly to the left is your heart, it is the size of your fist and is the most important muscle in your body. Just like the muscles in your arms and legs move and propel you about, the heart muscle has a special task in which it thrusts blood throughout your body as well as carries waste away. Your heart can pump more than 100,000 times a day pumping approximately 2,000 gallons of blood through 60,000 miles of vessels in the body. (Topel, EJ)
