The heart consists into three layers in which are endocardium, the myocardium, and the epicardium. The endocardium is the inner layer of the heart (chambers and valves). The myocardium is the middle muscular layer which is responsible for heart contraction. The epicardium is the outside layer of the heart
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 right and left sides of your heart are divided by an internal wall of tissue called the septum. The area of the septum that divides the atria (the two upper chambers of your heart) is called the atrial or interatrial septum.
The heart chambers have four valves categorized as atrioventricular or semilunar valves (Elisha, 2014). The atrioventricular valves include the tricuspid and mitral valves (Elisha, 2014). The semilunar valves include the aortic and pulmonary valves (Elisha, 2014). The tricuspid valve, located within the right atrioventricular orifice, lies between the right atrium (RA) and the right ventricle (RV) (Elisha, 2014). The mitral valve situated in the left atrioventricular orifice between the left atrium (LA) and left
A septal defect is the connection between left and right side of the heart. The opening in the atrial septum permits left to right shunting of blood. The opening may be small, as when the foramen ovale fails to close, or large, as when the septum may be completely absent.
These chambers are separated by valves to prevent back flow of blood (into the atria). Between the right atrium and the right ventricle is the tricuspid valve and between the left atrium and the left ventricle is the bicuspid valve. Separating the left ventricle and the aorta is the aortic valve and the pulmonic valve is found between the right ventricle and the pulmonary artery.
The heart is divided into four chambers; the superior chambers (atria) receive blood and are connected to the inferior chambers (ventricle), through the atrioventricular valves. Once in the ventricles, blood is ejected to the vasculature through the semilunar valves. These valves, similar to the ones in the veins, ensure the unidirectionality of blood flow.
The left chamber, lower at the heart, takes in oxygenated blood through the mitral valve from the left atrium while it contracts. The aortic valve leading to the aorta is closed while this occurs. At the same time, the aortic valve leading to the aorta is closed giving the ventricle the opportunity to fill with blood. The ventricles contract as both ventricles are full. When the left ventricles contract, the aortic valve opens as the mitral valve closes. When the mitral valve closes it prevents blood from coming back into the left atrium and the opening of the aortic valve giving way for the blood to flow into the aorta. From there it goes throughout the body. The left and right ventricles also contract together, but when the left ventricle
Atria: The heart is divided into four chambers that are connected by heart valves, the upper two heart chambers are called atria.
The inside of the heart is separated into four chambers, the left and right atria and the left and right ventricles. The ventricles hold responsibility for pumping blood around the body and they are the thickest muscle of the heart. The two atria form the curved top of the heart and the ventricles join at the bottom of the heart to create a pointed base which is directed towards the left side of the chest. The left ventricle contracts most forcefully, in order for the heart beat to be felt most strongly on the left side of the chest. A wall, known as the septum, divides the right and left sides of the heart and a valve connects each atrium to the ventricle below it. The mitral or bicuspid valve connects the left atrium with the left ventricle. The tricuspid valve connects the right atrium with the right ventricle.
The heart is a very complex organ that is necessary for life. The heart is responsible for bringing oxygenated blood around the body. There are two main ways of transportation of blood around the body. The arteries go around the body and bring the oxygenated blood to various parts of the body. Once the oxygenated blood is utilized, it is brought back to the heart by the veins. The heart is broken into four major chambers that are separated by four major valves. There are two atria, which are located at the top of the heart, and two ventricles, which are located at the lower half of the heart.  The atria and ventricles are connected by the Mitral (bicuspid), tricuspid, pulmonary, and aortic valve. Each valve closed after the contraction to
The heart contains four chambers, the right atrium, the left atrium, the right ventricle and the left ventricle. The right atrium is located in the upper right corner of the heart, above the right ventricle whereas the left atrium which is positioned in the left side of the heart separated from the right atrium and the left atrium. The atria has a very interesting texture, it has a thin, less muscular wall and is smaller in contrast to the ventricles. The atrium is joined to the veins that transport blood out to the heart and is categorized under the four hollow chambers of the heart. The left ventricle is situated in the bottom left portion of the heart. It lies under the left atrium separated by the mitral valve while the right ventricle is located in the lower right portion of the heart below the right atrium and opposite of the left ventricle. The aorta is the largest artery in the body; it begins at the top of the left ventricle. The right pulmonary artery begins at the base of the heart’s right ventricle. The left pulmonary artery passes horizontally in front of the descending aorta and left bronchus. The heart consists of four types of valves, the tricuspid valve located between the right atrium and the left ventricle, the pulmonary valve situated between the right ventricle and the pulmonary artery, the mitral valve positioned among the left atrium and the left ventricle and finally the aortic valve located between the left ventricle and the
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
