Heart Anatomy Research Paper

The heart is located between lungs and it is protected by the rib cage, it is thought to be the same size as a closed fist. The heart is protected a membrane called pericardium, this membrane contains a film of fluid which helps prevent fiction. Each side of the heart consist of an atrium and a ventricle. The right side of the

 Once the blood cell gets to the superior vena cava it goes through the right atrium and the right ventricle, then through the pulmonary artery and into the lungs.

The oxygen rich blood returns from the lungs and it goes through the pulmonary vein to the left atrium.

Once deoxygenated blood enters the right atrium, it travels through the tricuspid valve into the right ventricle. Then the blood goes through the pulmonary semilunar valve into the pulmonary arteries. Once in the pulmonary arteries the blood is pumped into the lungs where it is then oxygenated. The blood goes from the lungs through the pulmonary vein into the left atrium. From there it passes through the bicuspid valve into the left ventricle where it is then pumped out through the aortic semilunar valve into the aorta (Drake 101). From the aorta the blood goes to the right and left coronary arteries.

First the de-originated blood goes into the right atrium. And the originated blood goes through the left atrium. The right atrium then pumps blood through the tricuspid valve into the right ventricle, and the left atrium pumps blood through the bicuspid valve into the left ventricle. The right ventricle contracts, semi lunar valve opens and deoxygenated blood travels back to the lungs. The left ventricle contracts, semi lunar valve opens and oxygenated blood goes out to the body.

Likewise, Blood flows from the right atrium to the right ventricle, and then is pumped to the lungs to receive oxygen. From the lungs, the blood flows to the left atrium, then to the left ventricle, forming the complete circulation.

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

We are steps away from the most magnificent oxygen factory you have ever seen. Short and wide, the pulmonary artery begins at the base of the right ventricle and with a considerable size of 1.2 inches in diameter and 2.0 inches in length. Interesting fact: the pulmonary artery is one of the only arteries that carry deoxygenated blood. The other artery is the umbilical artery in the fetus. This is just something I remembered from an Anatomy class I used to take in college. The main pulmonary artery extends from the right ventricle of the heart and branches into left and right pulmonary arteries. The left and right pulmonary arteries extend to the left lung and right lungs.(Bailey, Regina 2013)

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.

Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where the blood picks up oxygen and returns

The right atrium is where the process begins. Then, blood travels through the tricuspid valve to the right ventricle, and from there to the pulmonary artery. Once the blood travels through the pulmonary artery, it reaches the lungs. While in the lungs, the blood goes through a gas exchange: deoxygenated blood gets oxygenated (The gas exchange takes place in the alveoli, which are tiny air sacs in the bottom of the lungs

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

A healthy heart pumps blood continuously through the circlutory system. It’s normal size is a little larger than a fist. The heart has four chambers, two on the right and two on the left. The two upper chambers are called the atria and the lower two are known as the ventricles. The right atrium takes in deoxygenated blood from the rest of body and sends it back out to the lungs through the right ventricle where the blood becomes oxygenated. Oxygenated blood travels from the lungs to the left atrium, then onto the left ventricle, which pumps it to the rest of the body.

The blood passes through the vena cava and into the right side of the heart, where the valves accelerate it towards the lungs through the pulmonary artery. It travels into capillaries and passes by the alveoli, where gas exchange occurs. Oxygen in the alveoli is taken by the red blood cells and carbon dioxide from the plasma is passed into the alveoli. The newly oxygenated blood travels through the pulmonary vein and back into the theart, this time the left side of it. The blood gets pumped through the aorta and other arteries before it gets to the cells it needs to go
