Pulmonary is word that means lungs or related to breathing. With pulmonary atresia, the pulmonic valve does not open at all and may indeed be completely absent. The main blood vessel that runs between the right ventricle and the lungs also may be malformed and the right ventricle can be abnormally small. In pulmonary stenosis, the pulmonic valve is stiffened and has a narrowed opening. It does not open properly, which increases strain on the right side of the heart because the right ventricle has to pump harder to send blood out to the lungs.
The other one is the aortic valve. These valves all work to keep the blood flowing forward.
They open up to let the blood move ahead, then they close quickly to keep the blood from flowing backward. Your beating heart creates a pulse. Your heart has to push so much blood through your body that you can feel a little thump in your arteries each time the heart beats. The most common places to feel a pulse are on your wrist and your neck. So try to find your pulse and feel the beat! Red blood cells have the important job of carrying oxygen. These cells, which float in your blood, begin their journey in the lungs, where they pick up oxygen from the air you breathe.
Then they travel to the heart, which pumps out the blood, delivering oxygen to all parts of your body.
The right atrium is one of the four chambers of the heart. After oxygen in the blood is released to the tissues, the now deoxygenated oxygen-poor blood returns to the heart through veins, the blood vessels that carry deoxygenated blood. This blood, which appears blue, enters the right atrium of the heart and then travels across the tricuspid valve into the right ventricle. The right ventricle is one of the four chambers of the heart.
It pumps deoxygenated blood through the pulmonic valve into the lungs. The oxygen in the air we breathe binds to red blood cells that are being pumped through the lungs. The oxygen-rich blood, which appears red, then returns to the left atrium and enters the left ventricle, where it is pumped out to the body once again. The septum is a thick wall of muscle that divides the heart.
It separates the left and right sides of the heart. A tiny tube that props a blood vessel open and makes sure blood flows freely. By listening to your heart, lungs, and belly, the doctor gets information about how things are working inside. For this test, the person exercises usually on a treadmill while the doctor checks breathing, heart rate, blood pressure, and electrocardiogram to see how the heart muscle reacts. A stroke can happen when part of the brain doesn't get enough blood due to a clot or a burst blood vessel. Blood normally flows from the right atrium to the right ventricle through the tricuspid valve.
In tricuspid atresia, the valve is replaced by a plate or membrane that does not open. The right ventricle therefore does not receive blood normally and is often small. The tricuspid valve lets blood flow from the right atria to the right ventricle. In an embryo, the aorta and the pulmonary artery are initially a single vessel. During normal development, that vessel splits to form the two major arteries. If that split does not occur, the child is born with a single blood vessel called the truncus arteriosus. There is usually a hole between the ventricles associated with this defect.
Your heart has four valves.
A valve lets something in and keeps it there by closing, like a door. The door shuts behind you and keeps you from going backward. Heart valves ensure that blood flows properly in and out of the heart. It's called the circulatory system, and the roads are arteries and veins. The two chambers at the bottom of the heart are called the ventricles.
The heart has a left ventricle and a right ventricle. Their job is to pump the blood to the body and lungs. One of the most common congenital heart defects, VSD is a hole in the wall septum between the heart's left and right ventricles. These can occur at different locations and vary in size from very small to very large. Smaller defects may gradually close on their own. White blood cells are part of the germ-fighting immune system. They are like little warriors floating around in your blood waiting to attack invaders, like viruses and bacteria. You have several types of white blood cells and each has its own special role in fighting off the different kinds of germs that make people sick.

However, you might have a change of heart based on what I tell you.
I promise that what I have told you today is true — cross my heart. Pulmonary is word that means lungs or related to breathing. Instead of two separate valves allowing flow into the heart, there is one large common valve that might be quite malformed. It's called the circulatory system and the roads are called arteries and veins. KA - th uh-ter: Such feelings of sadness would only break my heart , or make me feel unhappy and hopeless.
