EKG AMCA PRACTICE EXAM QUESTIONS ANDANSWERS
Answer: the tricuspid, the pulmonary semilunar, the bicuspid, and the aortic
semilunar valves are the four primary valves of the heart.
The atrioventricular septum, which is often referred to as the interventricular
septum, distinguishes the left side of the heart from the right side of the heart.
According to the answer, the superior and inferior vena cava supply the right
atrium with blood that has been deoxygenated.
It is the superior vena cava that is responsible for returning blood from the head and
chest.
It is the inferior vena cava that is responsible for returning blood from the lower
areas of the body.
tricuspid valve is the name of the valve that is responsible for separating the right
atrium from the right ventricles.
When a vein carries oxygenated blood, the pulmonary vein is the only vein that
receives oxygenated blood from the lungs. The left atrium is the only vein that
receives oxygenated blood from the pulmonary vein.
bicuspid valve is the name of the valve that is responsible for separating the left
atrium from the left ventricle.
dilatation is a syndrome that typically occurs in the atrium and is characterized by
the muscle wall becoming thinner and expanding in order to make room for more
blood.
, With the extoception of situations in which the pulmonary artery transports
deoxygenated blood, the right ventricle is responsible for pumping deoxygenated
blood through the pulmonary semilunar valve and into the pulmonary artery, which
then leads to the lungs.
Blood that has been oxygenated is pumped via the aortic semi-lunar valve and into
the aorta, which is the main artery of the body, by the left ventricle, which is the
strongest component of the heart.
According to the answer, hypertrophy is a condition in which the muscle wall
expands in order to improve the strength of the contraction. This condition typically
occurs in the ventricles.
The skeleton of the heart is made up of strong fibrous connective tissues that are
responsible for protecting the valves from opening during a contraction and
separating the atria and ventricles in order to ensure that each chamber of the heart
contracts independently.
The pericardium, epicardium, myocardium, and endocardium are the four layers
that make up the heart wall, which is composed of muscle.
The fluid-filled sac that surrounds the heart and allows the heart to contract and
expand within the chest cavity with minimal friction is referred to as the
pericardium.
The smooth, outermost layer of the heart, which contains the coronary arteries, is
referred to as the epicardium.
The myocardium is the layer of the heart muscle that is the thickest and is located
in the centre.
