The heart is one of many vital organs of the human body. To be more precise, the heart is a muscle about the size of a fist, that never rests (unless the person is dead) from working for the body. The purpose of the heart is to circulate oxygen carrying blood to parts throughout the human body, feeding the cells and keeping the person alive.

The heart circulates blood by “pumping” the blood throughout the body, noticeable by the beating. The process goes as follows; oxygen and nutrient deprived blood enters the right chamber of the heart, where the blood would then be pumped away to be refilled with oxygen. The new, oxygen and nutrient filled blood would then enter the opposite chamber on the other side of the heart where the blood would be …show more content…

The heart is also divided into two halves, with two chambers in each of them. The top, smaller chambers are called atriums, and the larger chambers below the atriums in the heart are called ventricles. In the heart, the chambers are used to separate the starved blood from the full blood. The oxygen deprived blood enters the right atrium via veins , and would then go to the right ventricle to be pumped to the lungs, where the full blood is then pumped into the left atrium, and would then go into the left ventricle, where the blood is then pumped back out throughout the …show more content…

The left atrium is one of two atria of the heart, and functions as receiving refilled/oxygenated blood, entering the heart from the lungs through the left coronary artery, which branches from the aorta. The left atrium pumps blood into the left ventricle, which would in turn pump the new, refilled blood back out into the body.

The right ventricle is one of the four main chambers in the heart, made of muscle, and is located below the right atrium. The right ventricle is also one of two ventricles in the heart, and functions as pumping the deoxygenated blood coming from the right atrium away to the lungs. In a normal heart, the right ventricle’s wall is less thick than that of the left ventricle. This is because the right ventricle pumps blood to the lungs only, whereas the left ventricle has to pump blood throughout the entire body constantly. This means the right ventricle has less work and pressure than the left

The cardiac cycle is the coordination of the filling and exhausting of blood by electrical signals that cause the heart muscles to contract and unwind. The contraction of the heart is directed by a nerve drive that goes from the SA node to AV node to AV group to Purkinje fibers to the myocardium. Amid the cardiac cycle, the heart contracts by means of systole, pushing blood out of the heart, and unwinds through diastole, filling the heart with blood. Cardiomyocytes, or cardiac cells, are striated and are in charge of the pumping of the heart; they are the main muscle cells with intercalated plates. The heart's inner pacemaker controls and times the thumping of the heart by means of electrical signals.

Normally, low-oxygen blood entering the right side of the heart stays on the right side, and subsequently oxygen-rich blood stays on the left side of the heart, where it is then pumped to the body and tissues. When a defect or "hole" is present between the atria (or upper chambers of heart), some oxygen-rich blood leaks back to the right side of the heart. It then goes back to the lungs even though it is already rich enough in oxygen. Because of this, there is a significant increase in the blood that goes to the lungs overall. Atrial septal defects can

Hypoplastic Left Heart Syndrome has many factors, stages and severities of the disease which could predict an outcome differently for each individual case. However if left untreated HLHS can be fatal. The left side of the heart is unable to supply blood to the rest of the body therefore the right side of the heart has to work harder to compensate for it. The right ventricle can support this circulation but will eventually cause right sided heart failure. Babies have two routes that can help support and carry blood between the left and right ventricles.

Vesalius had observed, by dissection, that there were no pores in the septum of the heart. This meant that direct transfer of blood was not possible. Harvey’s explanation for how blood was transferred from the right ventricle to the left ventricle was that it went through the lungs via the pulmonary arteries and returned through veins to the left auricle, and subsequently to the left ventricle. Once again this description was a simplified explanation of flow in line with his observations and those of Vesalius and

Deoxygenated blood is fed into the right atrium, pulled down into the right ventricle and then pumped to the heart along the pulmonary artery to the lungs. Once passed through the lungs, the now newly oxygenated blood is fed into the left atrium via the pulmonary vein and drawn down into the left ventricle. In order for the maximum volume of newly oxygenated blood to be then pumped out of the heart, via the aorta, to the rest of the body, the valve must open wide enough to allow the blood to make it into the ventricle, and close firmly enough to ensure that there is no backflow. If this does not happen, the maximum volume of oxygenated blood does not reach the rest of the body, and the system becomes inefficient as the cardiovascular system has to then work harder and faster to get the same volume of oxygenated blood to the surrounding body. This takes more energy, which could otherwise be better used.

First, it was 61 years ago, in 1954, that Dr. C. Walton Lillehei performed the fi rst cross-circulation procedures at the University. One year ago in January, Earl Bakken (the cofounder of Medtronic) turned 90 years old; Dr. Bakken has fi ve implanted Medtronic devices and continues to be an inspiration to those working in this fi eld. For the past 15 years, the University of Minnesota has presented the week-long short course Advanced Cardiac Physiology and Anatomy , which was designed specifi cally for the biomedical engineer working in the industry; this serves as the course textbook. Thus there was a need to update the textbook to include state-of-the-art information on a variety of topics related to cardiac anatomy, physiology, and devices. For example, six new chapters were added to this third edition, and all other chapters were carefully updated and/or greatly expanded.

A septum in the heart is located between the left and right ventricle chambers. The septum is a muscular wall that separates the deoxygenated blood in the right ventricle from the oxygenated blood in the left ventricle. A damaged septum is commonly called a ‘Ventricular Septal Defect’ and describes a condition where there is a hole between the 2 ventricles, the oxygenated blood from the left, flows into the right ventricle instead of being pumped to the body. The main cause of a damaged septum between the 2 ventricles, is being born with one. As a result of a damaged septum, the heart has to pump a lot harder for the oxygenated blood to reach all over the body.

“An average heart has four chambers; two upper, called the atria and two lower, called the ventricles. The right side of the heart receives blood that is returning from the body. This oxygen-lacking blood arrives in the right atrium, where it is pumped into the right ventricle. The right ventricle sends the blood to the lungs, where it is picks up plenty of oxygen. This oxygen-rich blood then enters the left atrium and is pumped into the left ventricle, which pumps blood through the aorta to all the organs and tissues of the body” (Blaser).

When the ventricles are full, the tricuspid and mitral valves shut which prevents blood from flowing back into the atria while the ventricles contract. As the ventricles begin to contract, the pulmonic and aortic valves are forced open and blood is pumped out of the ventricles.

Heart failure is when the heart is not functioning properly and becomes unable to supply the body properly with oxygen. Congestive heart failure is when this lack of function begins affecting the lungs ability to function normally by filling the alveoli with fluid. During normal functioning of the cardiovascular system, blood arrives at the right atrium of the heart via the vena cava. The right atrium empties blood into the right ventricle, which pumps it’s contents into the arterioles surrounding the alveoli of the lungs. From the lungs, the blood voyages to the left atrium of the heart.

Because of this inability to contract effectively, the rest of the vital organs receive inadequate amount of blood resulting to inadequate tissue perfusion. There are two types of left-sided HF; systolic and diastolic failure. Systolic failure happens when the left ventricle doesn’t have the enough energy to pump normally the blood to the general circulation. As for diastolic failure, the left ventricle loses the ability to fill itself with blood during resting period resulting to inadequate amount of blood to be pumped out to the circulation (Weinrauch, 2008). The diastolic dysfunction will eventually lead to right-sided heart failure.

The objective of this experiment is check how heart chambers, vessels and valves of the heart help the heart to achieve its function of pumping blood all over the body. In addition, this experiment would help us understand the double circulation of blood and reasons why it is vital for mammalian organisms. Due to the complexity of mammalian organisms, the exchanges of substances such as oxygen, nutrients and hormones cannot rely on diffusion itself (Kent, 2013). The transportation
