Heart

Either through the Superior Vena Cava located at the superior aspect of the heart, through the Coronary Sinus located at the inferior aspect of the heart, or through the Inferior Vena Cava located at the inferior aspect of the heart. All of these drain into the right atrium.

The bicuspid valve and the tricuspid valve connect the atria to the ventricles.

Yes - There are several reasons why someone's heart would stop. Heart disease is a primary factor causing heart attacks. Also - Genetic defects and hereditary defects causing arrythmias can stop a heat from beating.

A supraventricular tachycardia is tachycardia (heart rate > 100) that originates above the AV node, in the atria. There are several different forms of supraventricular tachycardia, including sinus tachycardia, atrial fibrillation, atrial flutter, atrial tachycardia, multifocal atrial tachycardia, and a nebulous condition called paroxysmal supraventricular tachycardia (PSVT). Many people also consider junctional tachycardia a supraventricular tachycardia.

"Allemande left" is a square dance term that comes from French baroque dancing. In square dance terminology, allemande left refers to when the couples hold one forearm and dance around each other.

The bacteria from the infection can especially if the dentist opens the tooth without the person being on antibiotic first. When they open the tooth without antibiotic the infection can spread and go up to the brain. If you leave the tooth unattended to it poses the same threat and it also can ruin other healthy pulp and roots of teeth. Yes, an infection in your teeth CAN lead to death, if not treated properly and quickly. It can also cause many other medical problems, such as heart muscle damage, lung infections and brain cell infections. The blood curculation system goes to all of your body and infection is carried by the blood, from your infected teeth, to the rest of you. Get it treated right away. While the above is true it would take a very long time and before that the pain would be so intense you'd be begging to go to a dentist. Always keep your teeth and gums healthy. If you can't afford a dentist, go to a dental school (the students there are excellent) or a clinic.

The heart is a muscle, but it is NOT in the muscular system, and pumps blood to all parts of the body :)

yes. your heartbeat is effected by music because if your listening to a high beat song and you feel like getting up and dancing you feel your heartbeat begin to rise. Then if your listening to a slow beat song right after that your heartbeat begins to fall and you fell relaxed. These things are the exact opposite of each other! and also you have a sense of rhythm and it moves you heart up and down.

Your muscles need a higher demand of oxygen during strenous exercise. That's when the brain realises that there needs to be more blood pumped round the body, in order to duly deliver oxygen with it to the muscles. Therefore the heart starts pumping faster, to pump more blood and therefore more oxygen to the body.

i hope that's what you asked:)

The left ventricle pumps blood to the entire body, while the right ventricle pumps blood only to the lungs, which are immediately adjacent to the heart. Hence, the left ventricle has to pump with greater force, and requires more muscle to do it.

the heart is situated just behind and slightly left of the breastbone, from this bone arises the ribs, the bones that go around the body trunk and defines the thorax. This anatomy is how the skeleton protects the heart.

Your heart grows only through your teenage years, just like your bones, genitals and female breasts. The best way to understand the size of your heart is to compare it to the size of your clenched fist (punching fist). An infant's fist is much smaller than an adult's fist. The size of the heart is roughly equal to the size of the fist.

The heart cannot continue growing through adulthood to old age because the cardiac muscle would not be able to fit in the chest or pump effectively if it kept growing. When the heart muscle is damaged and becomes flabby or unable to pump, the person can go into heart failure or can have a heart attack.

Normal impulse conduction

The heart is not considered a part of the digestive system. However you do have to remember that all organ systems are very inter-connected. For example, nutrients that diffuse through the walls of the the small intestine go directly into the bloodstream and are transported the the appropriate part of the body. That blood is pumped by the heart.

The organs that are directly involved in digestion, like the stomach or liver, could not stay alive without the constant pumping of blood by the heart. Without the heart, digestion could not occur. On that same token, digestion could not take place without the brain, or the lungs. However neither the heart, the brain, nor the lungs are considered a part of the digestive system.

It is a muscle and it is one of the strongest. Inside of the heart blood is transferred to either lung to get oxygen in exchange for CO2. The heart is basically the center of the circulatory system. All blood goes through it. All four chambers either contract or expand to flow the blood (both atria contract/expand at the same time, and both ventricles contract/expand at the same time)

Right atrium-receives o2 poor blood

Left atrium- receives o2- rich blood

Right ventricles- sends o2- poor to lung

Left ventricle-sends o2- rich blood to body

by the way i got all the info from my science teacher

Left atrium.

Ischemia can be prevented by a healthy lifestyle (including diet), regular exercise, a healthy weight, not smoking, moderate drinking, no illegal drugs, controlling hypertension, and managing stress.

Increasing heart rate does not increase stroke volume. At first, increasing exertion increases both heart rate and stroke volume. As the heart rate increases, the time spent in diastole decreases, so there is less time for the ventricles to fill with blood. The stroke volume therefore stops increasing, and as the heart rate approaches the maximum heart rate the stroke volume may begin to decrease.

Acute Myocardial Infarction (AMI).

The closing of the mitral and tricuspid valves results in the first heart sound. The closing of the aortic and pulmonic valves results in the second heart sound.

Listening to music not only affects our mood but also listening to a particular song can even modify the way we perceive the universe. Music processes on the right hemisphere of our brain. The way we experience it also affects our nervous system. Responding in different neutron to our brain, according what music we listen to.

because the body needs more oxygen in an active state therefore having to breath in more there fore having to use more energy there fore aving to pump blood around the body quicker therefore using the heart

the heart pumps blood around the human body
