The heart is a muscular organ in charge of pumping blood to all parts of the body. As the heart contracts, the blood is forced out through blood vessels and begins to follow a specific pathway. The blood makes it way through pulmonary circulation (to the lungs) and then through systemic circulation (the rest of the body).
Deoxygenated blood enters the right atrium through the superior and inferior vena cava. It then is transported to the right ventricle through the right atrioventricular valve (tricuspid valve). The ventricles contract and the valve closes so that blood does not flow back into the atrium. As the right ventricle contracts, it forces the deoxygenated blood through the pulmonary semilunar valve and into the pulmonary artery.
As blood travels through the circulatory system, it is first pumped from the right side of the heart to the lungs through the pulmonary arteries and then separates into arterioles which split into capillaries. Here, the deoxygenated
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.
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
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.
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).
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.
Blood then travels out toward the lungs for oxygenation via the pulmonary artery and returns to the heart through the pulmonary veins entering the left atrium. It is pumped through the mitral valve into the left ventricle to exit the aortic valve to the circulation via the aorta. The questions asked in the lab packet directly related to the anatomy and physiology of the heart which allowed to understand how the heart works as a
Next stop. Right atrium. One of the four chambers of the heart, the right atrium lets deoxygenated blood to pass through the tricuspid valve into the right ventricle and from there to the lung to oxygenate. The tricuspid valve, also known as right atrioventricular valve is located between the two chambers and it looks like flaps that blocks blood flowing back into the atrium. (Yahoo Health, 2013) The right ventricle of the heart has the mission to pump the blood into the pulmonary artery via the pulmonary valve and pulmonary trunk right into the lungs. Ready to go through the pulmonary valve into the pulmonary artery? Here we go! Weeeee…..
On the right side of your heart, it is collecting and pumping blood to the lungs through the pulmonary arteries, in which your lungs are refreshing the blood with a new supply of oxygen, and removing any waste products (Heart Disease- Mayo Clinic). On the left side of your heart, it pumps more blood throughout the aorta ( the main artery), to supply tissues throughout the body with oxygen and nutrients( Heart Disease- Mayo Clinic).
An understanding of the circulation of blood through the heart might help the reader to get an better understanding of how the different parts of the heart relate. It helps to think of all the blood vessels in the body as a huge, sophisticated railway network, where essentially all the blood in the veins throughout the body ends up in the vena cava, the railway end station. The superior vena cava receives blood from the upper part of the body, whereas the inferior vena cava receives blood from the lower part of the body. As the blood fills up in the RA, the increased pressure eventually makes the tricuspid valve shut open, allowing deoxygenated blood to enter the RV. As the deoxygenated blood flows into the RV, the pressure in front of the
The circulatory pushes blood throughout the body using the heart and veins. The heart is connected to the veins. It has two pumps to pump blood through the system.The right side of your lungs pump blood to the lungs the left takes in blood with lots of oxygen.
The heart is what keeps all living breathing species alive, animals or humans. If the heart was to shut down but the nervous system continued and was active, it would not matter. The entire body would shut down because once the supplier no longer delivers what is needed; organs will no longer function correctly, therefore causing irreversible damage. Arteries are what carried the rich oxygenated blood from the heart to the rest of the organs throughout the body. The Veins are what bring back the carbon dioxide blood to the heart. It then has to be put through a cycle so that it can be shipped back out. Blood travels from the right atrium through the tricuspid valve, to the right ventricle. From there, it is pumped to the lungs, the oxygen-rich blood goes to the left atrium and then through the mitral valve to the left ventricle where it goes to the aorta to be pumped around the body (Colombo 7). What looks to be a complicated process that would take hours or minutes is actually done in a matter a seconds.
The heart is described as the most valuable organ in the body. The function of the heart is to pump blood throughout the body. The heart works to pump and circulate all of the materials our body needs to operate properly. The right side of the heart receives de-oxygenated blood from the body. The blood rides through the Tricuspid Valve into the Right Ventricle. After that, it pumps through the Pulmonary Valve into the Pulmonary Artery. This is where the de-oxygenated blood is taken to the lungs to get oxygen.
