English Version:
Day and Night, in steady rhythm
There operates within the human body
A marvelous machine: the heart
The human heart is a hollow four-chambered organ
Deoxygenated blood enters the right atrium from the venae cavae
When the atrium contracts, blood flows into the right ventricle
Then it's off to the lungs for purification, while purified blood is evicted by
The left ventricle to the extremities
The heart is a muscular pump that maintains the circulation of our life's blood
Lub-dub, lub-dub... Sound familiar?
These are the sounds of your heart's valves opening and closing
The Heart
Aorta! You are the largest artery in the body
Aorta! You are the width of a garden hose
The heart is a muscular pump that maintains the circulation of our life's blood
It can continue to beat long after it's removal from the body, as we see in this
Turtle's heart
Arena rock band "Heart" had a number one hit in 1987 with the song
"Alone!"
"Alone!"
From the spritely actions of babyhood, down through the sedate pace of old age
The heart beats two and a half billion times. (About)
And then, you're dead
