Deoxygenated Blood Lab Report

When the left atrium is filled with blood, the heart contracts and the blood passes through the bicuspid valve and into the left ventricle.

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.

Both atria simultaneously fill with blood. Then the bicuspid and the tricuspid valves open, also simultaneously, to allow blood to flow into the ventricles. As the blood collects in the ventricles, they contract, ejecting blood into the lungs and the body. Meanwhile, the atria relax and again fill with blood.

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

The heart beats and pumps blood through our blood vessels, in which carries oxygen to our lungs. There are three main types of blood vessels in the heart circulatory, in which are the Arties, Capillaries, and Veins. The Arteries that is the aorta large artery carry oxygen blood away from the heart, the branch becoming smaller as they carry blood further from the heart into organs. Capillaries connect the arteries and veins allowing oxygen, nutrients and carbon dioxide pass through the cells. Veins are the one that passes through the vessels and remove waste products from our bodies.

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.

Mitral valve disease effects the cardiovascular system. In a healthy animal deoxygenated blood flows into the heart from the vena cava into the right atrium, it then passes through the tricuspid valve into the right ventricle. From here the blood travels through the pulmonary artery to the lungs where is it oxygenated, next it flows from the lungs to the left atrium via the pulmonary vein. Here it passes through the mitral valve to the left ventricle

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

The four valves of the heart are the tricuspid valve, the pulmonic valve, the mitral valve, and the aortic valve. The tricuspid valve is located between the right atrium and the right ventricle. It is responsible for allowing blood to flow from the atrium to the ventricle, preventing backflow of blood into the atrium. The pulmonic valve is located between the pulmonary arteries and the right ventricle and is responsible for allowing blood flow from the heart to the lungs. The mitral valve is found between the left atrium and the left ventricle, which allow blood to flow from the left atrium into the left ventricle preventing backflow of blood back into the left atrium. The aortic valve is found between the aorta and the left ventricle and allows blood to flow to the aorta and throughout 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.

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

Blood enters the right heart through a chamber that is called the right atrium. The right atrium is another word for “entry room”. Since the atrium is right above the right ventricle -which is the part that pumps oxygen lacking blood to the lungs-, a contraction pushes the 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 and it closes to prevent the blood from backwashing back to the right

The left side collects oxygenated blood from the lungs into the left atrium. From the left atrium the blood moves to the left ventricle which pumps it out to the body (via the aorta).

has to work harder pumping blood to the rest of the body. Blood in our
