Cardiovascular System Lab Report

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

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.

Left ventricle pumps the blood into the aorta, where the blood is supplied to the body tissues by the systemic arteries.

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

 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.

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

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 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

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.

Did you know the circulatory system comprises the heart, veins, capillaries and arteries? The system moves pure oxygenated blood in a continuous and controlled way from the lungs and heart so that blood can reaches every cell. Blood travels through a type of network of vessels that include capillaries that permeate every tissue of the body. Once it’s depleted of oxygen, the blood returns to the lungs and heart and the cycle continues.

Blood is one of the most vital components of the human body. The blood carries many functions such as to supply oxygen to the bodies tissues, remove metabolic waste products, regulate our core temperature as well as fighting infection and foreign bodies (Glover, 1997). The cardiovascular system is composed of the heart and its vessels. The heart is an involuntary muscle which receives blood to the atrias, which is then pumped via the ventricles. The vessels are composed of three main types. Arteries, veins and capillaries; all which transport blood throughout the entirety of the body. The constant action of both the vessels and heart ensure that the body receives a continuous supply of blood, keeping us within our homeostatic limits.

Oxygenated red blood cells enters the heart through pulmonary veins and goes into the left atrium. The oxygenated blood then goes through the mitral valve and into the left ventricle, mitral valve is activated, therefore it closes shut to prevent backflow of blood. The thick muscular wall contracts forcing blood out through the Aorta, the semilunar valves is activated so blood does not flow back into the left ventricle. The oxygenated blood is carried to the body.

The first main vessel that leaves the heart is the pulmonary artery and is the only artery that carries de-oxygenated blood and traveling through the lungs is then oxygenated and returned to the heart by the pulmonary vein and that is the only vein in the body to carry oxygenated blood. The now oxygenated blood leaves from the heart by the aorta and the splits to the carotid artery also known as the subclavian artery to the arms and the thoracic artery. The carotid artery leads to smaller arteries, arterioles and continuous capillaries around the arms and head and lead back to the heart first through the fenestrated capillaries, venule and medium sized veins and back to the largest vein that is called the jugular vein that is also known as

It then goes on to the right atrium where it expands when blood enters. It then goes
