Anatomy Structures

Right Atrium
Receives deoxygenated blood from the superior and inferior vena cava and pumps it into the right ventricle
Left Atrium
To pass oxygenated blood from the pulmonary veins into the left ventricle
Right Ventricle
Receives blood from the right atrium and then transports the blood to the pulmonary artery
Left Ventricle
Receives oxygenated blood from the left atrium and pumps it into the aorta
Right Coronary Artery
Network of blood vessels that carry oxygen and nutrient-rich blood to the cardiac muscle tissue
The body's largest artery. Takes oxygenated blood from the left ventricle to the body
Pulmonary Artery
Carry deoxygenated blood from heart to lungs
Superior Vena Cava
Brings de-oxygenated blood from parts of the body higher than the heart and returns the blood to the right atrium
Inferior Vena Cava
Receiving blood from the lower extremities and then pumping that blood to the right atrium of the heart.
Interventricular Septum
muscular wall that separates the left and right ventricles of the heart. With the use of the septum all the blood going round the body has been freshly oxygenated
thick middle layer of the heart that forms the bulk of the heart wall and contracts as the organ beats
it prevents chaffing of the heart and damaging its tissues by providing an additional layer of protective tissue and lubricating fluid called serous fluid.
Mitral Valve
It regulates blood flow from the upper left chamber (left atrium) into the lower left chamber (left ventricle), the heart's main pumping chamber.
Tricuspid Valve
ensures that blood flows from the right atrium to the right ventricle by closing an prevented back flow during ventricle systole
Chordae Tendineae
1 )bring right ventricular walls closer together during contraction.
2) pull the semilunar valves open to allow ventricular ejection.
3) pull the AV Valves open during atriole systole.
Papillary Muscle
Necessary for the integrity of mitral and tricuspid valve apparatus. They help in the closure and opening of the above said valves during myocardial contractility.
Aortic Semilunar Valve
Prevents blood flowing back into the heart from the arteries.
Pulmonary Semilunar Valve
Prevents backflow of blood from the pulmonary trunk (artery) into the right ventricle
