The heart deals with all things

The cardiovascular system is composed of the heart and blood vessels, including arteries, veins, and capillaries. The carotid arteries are the two large blood vessels in the neck that supply blood to the brain. KA - th uh-ter: It can be inserted into a blood vessel in the leg, arm, or neck and threaded to the heart during a cardiac catheterization. In this procedure, a long, thin tube is inserted into the patient's body to inject a special dye, which can show narrowed areas in arteries due to plaque buildup and find other heart problems.

The heart has four different sections, or chambers. These chambers are connected to each other by valves that control how much blood enters each chamber at any one time. The movement of the blood through the heart and around the body is called circulation.

Your heart is really good at it — it takes less than 60 seconds to pump blood to every cell in your body. SER-kyuh-luh-tor-ee system: The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation the system we usually think of as our circulatory system sends blood from the heart to all the other parts of our bodies and back again.

The Heart Is Deceitful Above All Things (novel) - Wikipedia

Coarctation of the aorta is a narrowing of a portion of the aorta, and often seriously decreases the blood flow from the heart out to the lower portion of the body. Congenital heart defects are abnormalities in the heart's structure that are present at birth. Congenital heart defects happen because of incomplete or abnormal development of the fetus' heart during the very early weeks of pregnancy. Some are known to be associated with genetic disorders, such as Down syndrome, but the cause of most congenital heart defects is unknown.

While they can't be prevented, there are many treatments for the defects and related health problems. You'll know that you've found your pulse when you can feel a small beat under your skin. Each beat is caused by the contraction squeezing of your heart. An echocardiogram test uses sound waves to diagnose heart problems. These waves are bounced off the parts of the heart, creating a picture of the heart that is displayed on a monitor. Getting an echocardiogram doesn't hurt at all. An electrocardiogram or EKG test records the heart's electrical activity. Sticky pads electrodes are placed on the chest and hooked up to a machine that records the heart activity onto paper or a monitor.

A doctor can interpret the EKG to see the heart beating and determine if it's normal. Getting an EKG doesn't hurt at all. An infection of the inner lining of the heart and heart valves. The heart is a strong muscle about the size of your fist. It pumps blood through blood vessels around the body and sits inside the chest, protected by the ribcage. The blood carries oxygen and other nutrients your body needs. A heart attack happens when a blood clot or other blockage cuts blood flow to a part of the heart. You know the sound of your heartbeat: In some people, there's an extra noise that the blood makes as it flows through the heart.

This sound is called a murmur. They're commonly heard in healthy kids with normal hearts, but an abnormal heart murmur can mean a person has a heart defect or heart valve problem. When the structures of the left side of the heart the left ventricle, the mitral valve, and the aortic valve are underdeveloped, they're unable to pump blood adequately to the entire body.

This condition is usually diagnosed within the first few days of life. You don't have any say over what this kind of muscle does and when. It just does its thing and works without you even thinking about it. Your heart is an involuntary muscle, which is how it keeps beating all day and night. Other involuntary muscles help digest food and are found in your stomach and intestines. The left atrium is one of the four chambers of the heart. The left ventricle is one of the four chambers of the heart. It pumps oxygen-rich blood out to the rest of the body.

Blood leaves the left ventricle through the aortic valve and enters the aorta, the largest artery in the body. Blood then flows from the aorta into the branches of many smaller arteries, providing the body's organs and tissues with the oxygen and nutrients they need. MY-truhl valve: The mitral valve lets blood flow from the left atrium to the left ventricles. In someone with mitral valve prolapse MVP , one or both of the valve's flaps don't close smoothly and collapse or prolapse back into the atrium.

The ductus arteriosus DA is a normal blood vessel in a fetus a baby before it is born that diverts blood flow away from the lungs. The lungs are not used until a baby is born — the fetus gets oxygen directly from the mother's placenta.

The DA usually closes on its own shortly after birth because the newborn can breathe on his or her own. PDA is common in premature babies.

This kind of doctor knows all about children's hearts and how they work. A kid with a heart problem will visit a pediatric cardiologist. Cardiologists treat all kinds of heart problems, from heart murmurs to high blood pressure. 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. If you want to watch people pretend to be the lowest of trash, sexually, physically and mentally abuse a 7 year old boy If you never want to witness such a thing I wish I never would have watched this mess. Its going to take some time to get over it. Very disturbing. I had to fast forward over half of it.

Its just too much to take. Some of the reviewers claim if you cant watch it then you must have been in an ivory tower and had a perfect childhood. I can assure you that is not the case without sharing details. But, this is rock bottom BAD. Like other reviewers, I find this too awful to watch all the way through. I have no objection to cinematographic depictions of abuse and atrocities for the sake of artful presentation and good story telling. This is just trash, filth and weirdness. It really violated my soul for the 45 minutes I was able to stomach it.

I thought it would be similar to Sherry Baby starring Maggie Gyllenhall sp , but it is not done tastefully and the writing is quite poor. I kept waiting for a scene, any scene to redeem this movie. It never happened. A very dramatic story that is emotionally draining but ends with no payoff. There is nothing redeeming about this movie. Even the shock value is overly developed and contrived.

And it is based on the fantasies of a writer who didn't even have these experiences yet pretended it was real. A very sad commentary on the aggrandizement of debasement and abuse, and the need and desire to appear shocking and cruel. I'm not sure anyone can say they "liked" this film. A survival story with a boy adjusting to each new circumstance all of which were crazy adult situations and environments he is subjected to. Trying his best to do what each adult required in their interpretation of what was right. I didn't find him to have gender confusion at all. He just did what his mother told him to do.

That was about her not him. It was his mothers game that she failed to explain to him. I would guess that she abused him and abandoned, much as she was, constantly.

She wanted him to be her toy that she could leave behind without a thought and then drag out when she felt like it. He never really had any idea what normal was. No kid does. I could see her in similar circumstances with her father, trying to please him in whatever scenario he required and then blaming her for his creative parenting. Kids are just trying to survive as best they can and look to the parents for what is expected.

It's all a play of no sense. I watched this when it first came out but had forgotten most of it so decided to watch it again and, I don't know if it's because I'm a little older, but I found the mother even more horrible this second time around, or perhaps I didn't pay attention the first time. If you like a movie that will send you reeling, you'll enjoy this. You can't completely blame her for be such a monster after seeing how she was raised and had to endure, she sadly passes it along to her son who was once such an innocent child.

Very heartbreaking. I think the book was better. It, as with all books, is written with greater detail to how the character is thinking. Yeah there are some interesting moments and decent I'm a big fan of Asia but Yeah there are some interesting moments and decent performances but it's too depressing.

As someone who had a crummy childhood, this took me right back to those bad experiences.
