The Artificial Heart The artificial heart is an extra pumping chamber that can pump blood throughout the body. The heart is a muscular pump that maintains oxygen and blood circulation through the lungs and body. Our heart pumps about 2‚000 gallons of blood throughout the day. An adult’s heart pumps blood at a rate of 60 to 100 beats per minute. The heart has two stages‚ in the first stage the left and right Atria contract at the same time pumping blood through the left and right ventricle. In the

1. How does the heart change as it develops in a fetus? At first‚ the heart is just a tube. It grows so fast that it needs more space‚ so it bends and twists back‚ forming the familiar shape. During the next phase‚ the two atria are partly separate but there is just one big ventricle. The next phase begins when the two atria are completely separate and the ventricles are just beginning to separate. Finally‚ the ventricles separate completely and the heart is developed. 2.

The vocabulary wasn’t very complicated and

The Mammalian Heart Analysis Questions 1. The job performed by the atria is collecting blood‚ while the job performed by the ventricles is pumping blood. Since the atria are thin-walled‚ they must function similar to thin bags that collect the blood. The ventricles have thick walls‚ which allow them to contract strongly to be able to pump blood to the rest of the body. 2. The deoxygenated blood must be pumped to the lungs‚ where it becomes oxygenated prior to be being pumped back to the rest

“Heart Cockle” Simple and plain to the human eye and tainted with splotches of a burnt orange‚ the shell is a living relic of its past‚ its prior experience.

THE HUMAN HEART The human heart is by far one of the most vital organs of the body. It has a mass that ranges from 250 grams to 350 grams.
