Why I Gave Up Conventional Medical Practice To Build a Non-Profit

I was in a restaurant, holding a steaming mug of hot java. With me were two friends. One I’ve known for 30 years. The other I’d just met 30 minutes back. The social dance was on. We explored vital questions. Who are you and who do you know? What do you do, and why? The … Read more

The Atrium – Storage Chamber and Booster Pump

In an earlier article, I’ve discussed the four heart chambers – the two upper chambers called atria, and the two lower ones called ventricles.

Let’s talk a little more about the atria.

The atria [singular : atrium] are thin walled upper chambers of the heart. There are two atria, one on the right and the other on the left.

The right atrium is located along the right border of the heart. The two great veins of the body – called the superior and inferior vena cava [SVC and IVC] – drain impure blood from the upper and lower halves of the body respectively. These two great veins ultimately empty into the right atrium.

From here, blood flows into the right ventricle across the tricuspid valve and thence into the lungs to be purified. The right atrium thus primarily functions as a storage chamber for “impure” venous blood en route to the lungs.
