How the Human heart works ?
The human heart pumps blood to every part of your body.
Heart is made up of four chambers, two on the right and two on the left.
The top two chambers are called the left and right atrium.
The bottom two are called the left and right ventricles.
Right Atrium:
The right atrium receives deoxygenated blood from the superior and inferior vena cava.
Left Atrium:
The left atrium receives newly oxygenated blood from your lungs.
Right Ventricle:
The right ventricle pumps the deoxygenated blood to the lungs through the pulmonary valve.
Left Ventricle:
The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
Tricuspid valve -
located between the right atrium and the right ventricle .
Bicuspid valve _
located between the left atrium and the left ventricle.
