Heart

There are a number of different phrases and names that have the acronym AVM. For instance, arteriovenous malformation, a medical issue in which arteries and veins have problems connecting, has the acronym AVM. Automated vehicle monitoring, automated valuation model, and application value management are also phrases that could be abbreviated with the acronym AVM.

the tissues will not function well because it has to be flexible so that the blood can fall or flow even if it is strong and the example of it was the artery it so big and very flexible so that when the blood fall in it strongly it cant be wisk.

Correct. Blood returning to the right side of the heart has already left the body and returned to the heart to be pumped to the lungs. There it will let go of carbon dioxide and pick up oxygen.

coronary circulation

There are 4 heart chambers. The two upper chambers are called atria while the two lower chambers are called ventricles. The valve separating the atria from the ventricles is called the atrioventricular valve. Then you would have your right and left atrioventricular valves.

the left atrium and left ventricle are the heart chambers which pumps blood toward the artery. . . xD

The main difference is the weight of the heart. the human heart weighs between 200 and 425 grams and the animals' hearts weighs 2267 grams. ANSWER Next human beings are animals; first, one needs to get over the notions of distinction, and then get to the diffirences. One thing human beings are very good at is looking at other creatures. Over a very long time, people have discovered that they have a lot in common with other animals. Again, once one gets past the distinction, a lot of matters are much easier. Like, talking about hearts.... Hearts, in just about everthing with more than one cell, have a sort of basic function: to move some kind of fluid throughout the structure. Animals. From earthworms to giraffes, all have hearts. And all are animals....

The heat pumps and sends the blood to different parts of the body. The heart beating looks like the pump.

Oxygen-poor, or deoxyginated blood starts in the right atrium, goes through the right atrioventricular valve and enters the right ventricle. It then goes through the pulmonary valve into the pulmonary trunk. It then goes through pulmonary arteries to the lungs, enters the capillaries in the lungs to pick up oxygen, then returns to the heart through the pulmonary veins and into the left atrium. This is the path of de-oxygenated blood

Aortic Semilunar Valve

the septum divides the teo ventricles of the heart.

The second heart sound (S2) is a short burst of auditory vibrations of varying intensity, frequency, quality, and duration. It has two audible components, the aortic closure sound (A2) and the pulmonic closure sound (P2), which are normally split on inspiration and virtually single on expiration. S2 is produced in part by hemodynamic events immediately following closure of the aortic and pulmonic valves. The vibrations of the second heart sound occur at the end of ventricular contraction and identify the onset of ventricular diastole and the end of mechanical systole.

• Irregular heart beat,
• heart muscle weakened,
• heart failure,
• low pulse and blood pressure

OBViously, u cannot CURE heart disease, by chewing gum, though, you could prevent heart disease. THis is because, one of the causes for heart disease is bad breath, surprisingly, so, If you chew gum (especially mint) it could help prevent heart disease, but not CURE.

The pericardium is a double walled sac that encloses the heart, and the proximal ends of the aorta, vena cava, and the pulmonary artery. The visceral layer is next to the heart, then a bit of fluid, and the parietal layer is outermost. In trauma, it can become filled with blood and impinge on the heart. Peri - means around, and - cardium means heart.

The importance of the heart to the human body, is, simply saying:

life maintaining organ which pumps and circulate the oxygented blood through out our body. main function is homeostasis, that maintenance of internal environment with the help of certain hormones like adrenalin. it provides both central and peripheral circulation by which it provides nutrition to all the cells of the body.

Every cell, tissue, muscle, etc. needs oxygen to perform its function. The heart is a smooth muscle which needs oxygen and circulates oxygen throughout the body.

When we breath out, the lungs release carbon dioxide. When we breathe in, oxygen molecules collect on small sacs in the lungs called aveoli. The aveoli look like upside-down groups of grapes, at the farthest ends of the bronchioles. As blood passes the aveloi, oxygen attaches to hemoglobin on red blood cells. The arteries push the blood through the heart to the brain...and to the major abdominal organs...then to the legs and feet...

All along the way, red blood cells "drop off" nutrients and oxygen to tissues through special processes within cells.

Then, from your legs, abdomen (ribcage to privates), arms, and your brain, capillaries return carbon dioxide and cell waste up through your body using special valves in the blood vessels (the valves only open one way - back toward the heart). The blood passes through the heart, to the lungs where it drops off carbon dioxide which you breathe out. At the same time, the kidneys act to filter certain waste products carried by venous blood (venous is non-oxygenated--- arterial is oxygenated). Although a heartbeat happens in a split second, with every heart beat the blood makes this continuous route out through your body and back.

As such, the respiratory system and cardiac system work in conjunction with each other all the time. If one of these fails, death can result. If one system becomes diseased, both systems begin to work harder to do the same jobs.

I don't know for a 2 year old, but i do know that the average human heartrate goes from 90-100 beats per minute, well, I'm not sure about that either. I got it from Ripley's Believe It or Not.

The foramen ovale is an opening whereby blood is allowed to travel from the right atrium to the left atrium, bypassing the lungs. The reason for bypassing the lungs is because the fetus does not need to use them while in the womb as the mother's blood supplies oxygen. However, if the foramen ovale isn't closed after birth, typically there are no cardiac complications.However, there have been possibilities (though not yet proven) that there can be increase risks of stroke/ blood clots, migraines, and possibly cyanosis.

Slow Heartbeat at Rest is good The slower your heart beats with activity, the better shape your heart is in. The heart beats faster in order to provide 02 (oxygen), and if your are in super physical shape, the heart will beat at a more normal pace for a given pace. At the same time, elite athletes will be able to push themselves to even more intense levels, such that their maximum heart rate increases during extremely intense exercise. Also, the heart rests when you do. If you have an elevated heart rate at rest, it could be due to many different factors. Some examples: large caffeine intake, anemia, stress, lung disease, pain, or even a heightened emotional state (nervous, excited, angry). Another important thing is how quickly your heartrate can recover to a normal beat after strenuous exercise.

Answer2: Better check things with your doctor. Before surgery two years ago I found out I have a very slow heart rate. After test and wearing a halter monitor for 24 hours, my doctors said it's my normal. Exercise makes the heart rate even lower, but my doctors don't seem really concerned because they say a slow heart rate is better in general.

Many variables here. What you are stabbed with? What is your condition level? What part of the heart is stabbed? How many times you are stabbed? How many chambers of the heart are compromised? Is the pericardium able to let the blood out or holding it in causing a tamponade (stopping the heart from filling because of pressure outside the heart)? What the weapon left in or pulled out? Large knife penetrating completely through the heart - left in, about a minute or so - pulled out, very quickly. Small knife or screwdriver penetrating the heart completely - left in, you could live to tell about it - pulled out a tamponade death within seconds. Just the left ventricle - weapon left in, you have chance to live to tell about it - just the right ventricle, or either auricle, weapon left in, maybe you make it - pulled out, a tamponade death within seconds. I survived a 7" long, 1" wide blade completely through the left ventricle and survived because the knife was left buried in my chest and a officer found me just after I was stabbed. He knew how to keep me going until the medics got there. People do survive - but usually because they get immediate help, are in good condition and the weapon is left in.

Well, depending on the type of music, music can affect your sleep in a good way. soothing music can help you fall asleep easier, while noisy music like rock can disturb you and cause you to wake up several times in the night.

It also depends on how loud the music is, and what ones personal preference of music is. Waking throughout the night is not the only side effect. Other effects include, but are not limited to: psychological disturbance, a change in the sleepers dream (and everyone does dream; it has been proven), and causing mild to severe mood changes that aren't normally in the personality of the sleeper, once the sleeper wakes that is.

Well Music has a big effect.for example, try http://www.easysleepmusic.com or check them out on YouTube. There relaxing music/sleep music wat ever it is, literally knocks you out in bed.

Your heart rate should increase after eating, although it should not become uncomfortable. The reason it increases is because the body is working to digest the food you just ate and transfer it to energy. The blood is rushing to your stomach and other organs needed to digest your food and your heart must therefore pump faster. It's normal. If it increases beyond 100-110, consult your doctor. You may have an accelerated heart rate, which is not good, but can be treated with beta blockers.
