The Heart 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

1. The pulmonary circuit is supplied by which ‘side” of the heart? The systemic circuit? The right atrium

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 is one of the strongest muscles in the body. According to Henry Gray's “Anatomy of the Human Body” (2015), the heart is roughly the size of a large fist and weighs between about 10 to 12 ounces (280 to 340 grams) in men and 8 to 10 ounces (230 to 280 grams) in women (Lewis, 2015). The human heart has four chambers: two upper chambers (the atria) and two lower ones (the ventricles). The heart's outer wall consists of three layers; epicardium (outermost wall), myocardium (middle wall), endocardium (inner layer). The tricuspid valve and the mitral valve make up the atrioventricular (AV) valves, which connect the atria and the ventricles (Lewis, 2015). The function of the heart is divided into two pathways: the pulmonary circuit and the systemic circuit. In the pulmonary circuit, deoxygenated blood travels to the lungs by way of the pulmonary artery, then returns as oxygenated blood to the left atrium of the heart via the pulmonary vein. The systemic circuit, delivers oxygenated blood to the body from the left ventricle to the aorta, and from there enters the arteries and capillaries where it supplies the body's tissues with oxygen. Then, deoxygenated blood returns through the veins to the venae cavae, re-entering the heart's right atrium to restart the

The circulatory blood flow is divided into two sections. The pulmonary circulation it consists of blood vessels that are responsible for the transportation of blood through the lungs to be oxygenated and they return the waste gases picked up along the way and then returned through the body blood vessels for the arrival trip back to the heart The pulmonary circuit is a short loop that rapidly oxygenates the blood. It leads from the heart's right half to capillary beds in both lungs, and then returns to the heart's left half. In the circulatory system there is a path of blood that flows, blood from the body’s tissue it enters on the via the superior and inferior vena cava the right atrium. The

The systemic circuit also does two things: brings oxygen-rich blood to the entire body besides the lungs and oxygen-depleted blood to the heart. Blood flows out of the left side of the heart to the aorta. Aorta is the name of the artery which brings oxygen-rich blood to the entire body. This blood is then transported from the aorta to connecting arteries and capillaries. Diffusion takes place in the capillaries in which the blood becomes oxygen-depleted and takes in carbon dioxide, unlike the pulmonary circuit.

From the right atrium the blood moves into the right ventricle through the AV valve. When the ventricles contract the blood is moves through the semilunar valve into the pulmonary artery. This artery then branches off into the left lung and the right lung so that the blood can become oxygenated. The oxygen-rich blood returns to the left atrium of the heart through the pulmonary veins.

The direction blood flows from the heart to lungs and back to the heart: Deoxygenated blood enters the heart through the right atrium. The contraction of the right atrium forces blood through the atrial ventricular valves known as the tricuspid and bicuspid valves. Once the atria fills up, the valves open, and blood is able to pass through the right ventricle. The right ventricle contracts to force blood into the pulmonary semi lunar valve into the pulmonary lunar artery. The blood travels through the pulmonary arteries to the lungs to get oxygenated. Once it gets oxygenated, it then returns back to heart through pulmonary veins, then the left atrium, then through the bicuspid valve to the left ventricle, then through the aortic semi lunar valve, then to all the tissues of the

Systemic circulation loops: then systemic circulation loops transport the oxygenate-rich blood from the left atrium to then left ventricle. From there, the heart pumps the oxygenated blood to the rest of the body. The systemic circulation loops also get rid of waste from body tissue and return deoxygenated blood back to the right atrium.

The heart's main purpose is to deliver oxygen to the body and clean the body from the digestion (carbon dioxide). Cardiac perform these purposes by accumulating oxygen-depleted blood from the body and pushes it to the lungs, where the blood will be taking in oxygen and disposing of carbon dioxide; the heart then collects oxygen-rich blood from the lungs and pumps it into tissues through the

Heart= The heart is around the size of a persons fist, it is composed of 2 sides and four chambers, the left and right atria and the left and right ventricles. The atria’s are at the top of the heart, they receive blood from various parts of the body. The two ventricles are located on the bottom of the heart and pump blood away from the heart. The right ventricles responsibility is to pump the deoxygenated blood to the lungs, while the left ventricle pumps the oxygenated blood to the rest of the body. Between the chambers there are valves in the heart, the valves control the flow of blood, making sure it flows in one direction.

The heart is not only responsible for pumping blood through the entire body, but it also requires its own blood supply in order to perform its function. This is known as coronary circulation. The cardiovascular system has two circulatory paths; pulmonary circulation, the circuit through the lungs where blood is oxygenated and systemic circulation, the circuit through the rest of the body to provide oxygenated blood. Pulmonary circulation is the movement of blood from the heart to the lungs for oxygenation, then back to the heart again. Oxygen leaves the systemic circulation when it is entered in the right atrium through the vena cavae. Then it travels through the tricuspid valve into the right ventricle. The blood is pumped through the pulmonary

The process starts first with the entrance of blood into the right atrium. From the right atrium than the blood goes through the tricuspid valve to the right ventricle. Then the heart pumps the blood from the right ventricle to the pulmonary valve. From there the blood moves through the pulmonary artery and then into the capillary beds of the lungs where gas exchange occurs. From the lungs, the blood goes through the pulmonary veins to the left atrium of the heart. From the heart, the blood then goes down through the mitral valve. From the mitral valve, it flows down into the left ventricle. After that, the left ventricle pushes the blood up into the aorta. The blood then moves into arteries then back up to right atrium again then the cycle

The heart sits in the thorax between the lungs in a sac called the pericardium. The heart beat 2 to 3 billion times in a lifetime. Every Arteries, veins, and capillaries in our body can transfer oxygen and energy to every cell. The right ventricle pumps the blood to the lungs. The left ventricle pumps blood to the whole body. The left atrium receives fresh blood after was in lungs and pump, it through the mitral valve.

The heart is the muscular pump that pumps blood around the body and to all the major body parts. The heart is located just to the left of your sternum. The left ventricle pumps blood through the aorta to the systemic circulation while the right ventricle pumps blood towards the lungs and rest of the body. Blood enters the heart through both of the atriums, blood goes into the right atrium via the inferior and the superior vena cava. The right side pumps deoxygenated blood in the veins in the
