“An average heart has four chambers; two upper, called the atria and two lower, called the ventricles. The right side of the heart receives blood that is returning from the body. This oxygen-lacking blood arrives in the right atrium, where it is pumped into the right ventricle. The right ventricle sends the blood to the lungs, where it is picks up plenty of oxygen.

That is the structure of the heart, and that so happens to be the most important organ in an organism’s body. The heart helps people get oxygen, keep the organs alive, and it keeps us alive. If this major organ fails and has problems, them that will be really bad. Although There are other major problems in the health world, cardiac problems should be prioritized by doctors.

(Williams is today known as the first surgeon to open the chest cavity successfully without the patient dying from infection)” (“Open Heart Surgery”) Heart surgery was once impossible. Imagine all of the people who died from these awful problems, because nobody could fix the problems they were having. They did not know how the keep the heart beating through surgery, especially open heart surgery. But, they eventually did it and now it is
