3D Heart Beat Sound Effect with realistic blood flow.
Low oxygenated blood (blue) enters the right atrium
passes through the tricuspid valve into the right ventricle
enters the pulmonary valves drains into the pulmonary trunk
entering the lungs to exchange carbon dioxide for oxygen
now the oxygenated blood (red) return through the pulmonary veins (the only veins in the body that carry oxygen-rich blood)
and drains into the left atrium
from the left atrium they flow past the mitral valve into the left ventricle
left ventricle pumps the blood through the aortic valve toward the big circulation in the body.
A brief in 2 sentences : The right side of the heart pushes dirty blood in the lungs, then the left side of the heart receives the blood and pumps it throughout the body.
The typical process above is called a cardiac cycle, it lasts about 0.8 sec.
With every cardiac cycle a pulse (heart rate vibration) is generated, you can feel it by gently touching the artery of your wrists.
The heart is a muscle. (the cardiac muscle)
the heart beats about 70 times per minute at rest and can reach 200+ beats per minute during intense exercising.
The beating sound of the heart is generated by the opening and closure of the valves.
On average the heart pumps 2000 gallons of blood everyday, it never stops beating in normal circumstances.
The contraction of the ventricles in the heart is called Systole, the relaxation of these 2 chambers is called Diastole.
The amount of blood ejected by the left ventricle is called "stroke volume", it equates 4-5 tablespoons (75ml).
Unlike all the other cells in the body, the heart receives its nutrients during the relaxation phase "diastole" that is when the capillaries in this muscle are not obstructed which allow blood flow into them.
If the heart stops beating we call it "Asystole" or cardiac arrest.
The brain is the first organ to get affected if the heart stops beating, no more blood gets to the brain and this translates by a syncope "loss of consciousness" due to lack of oxygen and sugar (the fuel of the brain).
Leading cause of death worldwide is heart disease.
It is possible to replace the heart with an artificial metal one.
