Key Terms:
Left Atrium – one of the four chambers of the heart, located on the left posterior side
Right Atrium – one of the four chambers of the heart, located on the right posterior side.
Left Ventricle – one of four chambers of the heart. It is located in the bottom left portion of the heart below the left atrium, separated by the mitral valve.
Right Ventricle – one of the heart's four chambers. It is located in the lower right portion of the heart below the right atrium and opposite the left ventricle.
Bicuspid (Mitral) Valve – the valve between the left atrium and the left ventricle of the heart, consisting of two tapered cusps.
Tricuspid Valve – a valve that is situated at the opening of the right atrium of the heart into the right ventricle and that resembles the mitral valve in structure but consists of three triangular membranous flaps
Pulmonary Valve – one of the four valves in the heart, which stands at the opening from the right ventricle in the pulmonary artery trunk.
Aortic Valve – the semilunar valve separating the aorta from the left ventricle that prevents blood from flowing back into the left ventricle.
Aorta – the main artery of the body, supplying oxygenated blood to the circulatory system.
Vena Cava – a large vein carrying deoxygenated blood into the heart
Pulmonary Artery – the artery carrying blood from the right ventricle of the heart to the lungs for oxygenation.
Pulmonary Vein – a vein carrying oxygenated blood from the lungs to the left atrium

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 is divided into four chambers, upper left, upper right atrias, lower left and lower right ventricles. The right atrium and ventricle are called the right hearts and the left as the left hearts. The heart is enclosed in a protective sac, the pericardium, which contains a small amount of fluid. There are
The mitral valve is located on the left side of the heart between the left atrium and left ventricle. The purpose of the mitral valve is to form a seal between these two chambers of the heart to prevent the back flow of blood. When blood enters the left side of the heart, it is oxygenated and enters through the pulmonary veins. The blood then travels through the left atrium; the bicuspid (mitral) valve then opens to let the blood flow down to the left ventricle. The left ventricle contracts, causing the mitral valve to close (preventing the backflow of blood).When the left ventricle contracts it is pumping the blood out to the remainder of the body. (Jenkins, 2007)
Next stop. Right atrium. One of the four chambers of the heart, the right atrium lets deoxygenated blood to pass through the tricuspid valve into the right ventricle and from there to the lung to oxygenate. The tricuspid valve, also known as right atrioventricular valve is located between the two chambers and it looks like flaps that blocks blood flowing back into the atrium. (Yahoo Health, 2013) The right ventricle of the heart has the mission to pump the blood into the pulmonary artery via the pulmonary valve and pulmonary trunk right into the lungs. Ready to go through the pulmonary valve into the pulmonary artery? Here we go! Weeeee…..
Locate the mitral valve (or bicuspid valve) between the left atrium and ventricle. This will have two flaps of membrane connected to papillary muscles by tendons.
The heart is a cone-shaped organ approximately the size of a fist with an apex and a base. It is located within the mediastinum or medial cavity of the thorax. The heart is enclosed within a double walled pericardium, a fibroserous sac. The pericardium has a superficial fibrous pericardium and deep two-layer serous pericardium. The
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.
You have four chambers in your heart. Two atria in the upper half of the heart and two ventricles
HLHS is referred to as single ventricle. The abnormal mitral valve preventing the blood from entering the left ventricle as a result blood flow is then diverted across ASD and into the
The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).
The heart is located in the chest between the lungs behind the sternum and above the diaphragm. It is surrounded by the pericardium. Its size is about that of a fist, and its weight is about 250-300 g. Its center is located about 1.5 cm to the left of the midsagittal plane. Located above the heart are the great vessels: the superior and inferior vena cava, the pulmonary artery and vein, as well as the aorta. The aortic arch lies behind the heart. The esophagus and the spine lie further behind the heart.
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.
The heart is basically a pump that has to circulate the blood around the body delivering oxygenated blood to our organs and then returning deoxygenated blood to our lungs. There are four chambers in the heart, two atria and two ventricles. There are four main valves, mitral, aortic, tricuspid and pulmonary7b.
The Heart is hollow organ which is composed of four muscular chambers the right and left atrium and ventricles that is specialized for pumping blood throughout the body. The heart is also consists of four valve; two atrioventricular valve which is the bicuspid and tricuspid valve that is allowing blood to flow in the atria and closes when there is a increase ventricular pressure that prevent backflow into the atria as ventricles contract (Craft, Gordon, and Tiziani, 2011), and the semilunar valves which include the pulmonary and aortic valves is located at the exit of the large arteries from the ventricles that opens when there is intraventricular pressure exceeded the aortic and pulmonary pressure which allows the blood flow into the systemic
