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.
