By the way, doctor: What can be done about a growing heart?
Q. My doctor told me my heart is growing. He says there is no cure. Do you know of anything to reverse or slow down the growing heart? I am an 86-year-old World War II veteran.
A. Each of the heart's four chambers is a blood-filled space surrounded by a wall of heart muscle. These four chambers work as four separate pumps, pushing blood around your body.
Four chambers of the heart
Most people are born with a small but perfectly shaped heart that grows in proportion to the rest of the body. Once you stop growing, your heart stops growing.
