Question

Describe the structure of the heart and it's working? what kind of sound does heart have?

Answer 1

a muscular pumping organ that pump out the blood into the blood vessels is called heart . Its size is as big as our fist . Human heart is four chamberd.

Answer 2

The heart is divided into four chambers consisting of two atria and two ventricles; the atria receive blood, while the ventricles pump blood.

The right atrium receives blood from the superior and inferior vena cavas and the coronary sinus; blood then moves to the right ventricle where it is pumped to the lungs.

The lungs re-oxygenate the blood and send it to the left atrium.

Blood moves from the left atrium to the left ventricle via the bicuspid valve; blood is pumped out of the left ventricle to the aorta, which sends blood to the organs and muscles of the body.

The heart is composed of three layers: the epicardium (outer layer), the myocardium (middle layer), and the endocardium (inner layer).
