Deoxygenated Blood Lab Report

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.

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.

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

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

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 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

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.

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.

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

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

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 heart has two sides, the left and the right, which are separated by the septum. Each side has an atrium and a ventricle with valves separating them (to prevent blood from flowing backwards) (Atria and ventricles are chambers of the heart). They are also connected to various arteries (blood vessels that transport blood away from the heart) and veins (blood vessels that transport blood towards the heart). The left side of the heart receives the blood coming from the lungs, the blood filled with oxygen, and pumps it to the rest of the body. The right side

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.

This maintains a proper one directional blood flow through out the process. Bicuspid valve is present between the left atrium and left ventricle whereas tricuspid valve is present between the right atrium and right ventricle. Pulmonary valve behaves as a gate which stops the back flow of blood from right ventricle to the pulmonary artery which takes the deoxygenated blood to the lungs for purification. Lastly the aortic valve, this valve plays an important role in stopping the back flow of the blood from left ventricle to the aorta. Once the blood is transferred to the aorta it supplies the oxygenated blood to different parts of the body.

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).
