Heart

The heart is a major organ of the body that is found in the circulatory system. It pumps blood throughout the blood vessels. Questions related to the heart should be put here.

... to the aorta, the major artery coming from the heart. It then travels through the systemic circuit, circulating through all of the blood vessels of the body.

How is the DNA of your brain cells the same as the DNA of your heart cell?

DNA is found in a heart cell and brain cell and they both do a job in each cell.

Has a person ever been scared to death?

User Avatar
Yes. Notably (and unfortunately), this happened in 2008, when a fleeing bank robber broke into a 79-year-old woman’s house to hide from police. The woman died of a heart attack, and the robber was given a life sentence for causing her death. While every cardiac event is different, here’s some information about what fear does to your heart: When you feel you’re in danger, your brain orders a surge of adrenaline to course through your body—this triggers your fight-or-flight response, which, among other things, raises your heart rate. The intent is to pump blood to your muscles and other vital organs, preparing you for battle or escape, but in extreme circumstances and risk-prone hearts, this can cause a heart attack. That’s horrifying, but death by fear is rare. Here’s Vincent Bufalino, MD, in his interview with the American Heart Association: “You can have a sudden cardiac-related event related to an adrenaline surge, but I think it would be a stretch to say you could get that from someone coming in a werewolf costume to your front door. [Something that will give you a heart attack] is the kind of thing that you can't prepare for. If it happens, it happens, and you hope your body doesn't overreact to that event.” So, yes, someone has been scared to death, but this isn’t something you need to worry about.

Trace a drop of blood through the pulmonary and systemic circuits fo the heart?

User Avatar
Blood from the body gets returned to the heart through the superior vena cava where it enters the first of four chambers of the heart- the right atrium. It then would pass through the tricuspid valve and into the right ventricle. From there it would pass through the pulmonary valve and go through the pulmonary arteries and into the lungs. The lungs oxygenate the blood and it returns to the heart via the pulmonary veins. This blood enters the heart chamber called the left atrium. It travels through the mitral valve and into the left ventricle. As the heart pumps, the blood then exits the heart through the aortic valve, and goes out the aorta where the blood is then carried to the brain and other organs of the body.

Your apex is not an organ, but is part of an organ. There is the apex of the heart and the apex of the lungs (apex pulmonis), both organs.

Why doesn't the heart symbol look like an actual heart?

User Avatar
There are a couple different theories, but the oldest instance of the symbol can be traced back to ancient Rome. It appeared on coins from the Roman colony of Cyrene, mimicking the seed of an ancient plant called silphium. This plant was crucial to the Cyrene economy and was said to have medicinal properties. Additionally, in those days the silphium seed was used as a form of contraceptive, and thus became associated with love and intercourse. So, according to this theory, the shape wasn’t even supposed to represent a heart at first—thanks to autopsies, Romans were well aware of what the anatomical heart looked like. Over time, the heart came to be associated with depictions of silphium seeds because both were already separately associated with love. Another theory holds that the symbol originated from the philosopher Aristotle, who described the human heart as having three chambers with a dent in the middle. Some believe the shape came into existence as scientists and artists from the Middle Ages attempted to bring Aristotle’s description to life.

"Yes, this is actually a newer surgery option. Doctors can do this surgery and replace your mitral valve with another valve in your body, or another persons body."

The heart symbol is an artistic impression of a heart - related to love. I don't think someone would appreciate an actual picture of a real heart on their Valentine's Day card!

The human heart is the pump in our circulatory system. We know blood needs to move around within our bodies to supply building materials to our cells while taking waste away. And we also know that the blood must be in constant circulation to do this. The muscles of the heart contract in rhythm to force blood through our circulatory system, which is made up of the arteries and veins. In this closed system, pressure developed at a point is felt throughout the whole system, and the heart develops that pressure. The heart's main function is to pump blood, making it the functional core of the circulatory system. Incoming, deoxygenated blood is pumped through the right side of the heart and to the lungs, where the carbon dioxide is replaced with fresh oxygen. This renewed, oxygen-rich blood the makes it way back to the left side of the heart, where it is then pumped back out to the rest of the body where it starts its journey around and back all over again.
