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.

What is the name of the several bones in the heart?
There are no bones in the heart. The heart is a four chambered muscular pump.
How much does heart sergeon get paid?
In total, the average Heart Surgeon makes about $375,000 dollars a year. Most Heart Surgeons are on contract with hospitals or surgery centres. Not many Heart Surgeons practice privately unless they do regular Cardiology consults on the side. The Heart Surgeons that are on contract are paid monthly.
$375,000/12 months (1 Year) = $31,250 a month.
I like the sound of that paycheck!
The study of the heart can be called anatomy but is it just anatomy?
If your studying anatomy, you are studying the inner systems of living creatures. Systems such as the muscular, nervous, skeletal, cardiovascular, respritory, endocrine...etc.
The study of the heart is included in anatomy.
The study of the heart can be narrowly classified as "Cardiovascular Science"

How many times does a heart beat in an average life time?
5000 trillion times in a life time. Only if you die at an early age.
What does i need you like a heart needs a beat mean?
well you can't live without a heart beat. so it means i can't live without you!
How do you dump a boy without breaking his heart?
dont do it by text say it to their face ,tell them the truth why u dumped them e.g if they were to clingey tell him and afterwards dont tell everyone you dumped him boys feel less manly is someone asks then you can tell them
Is it better to have a lower or a faster heart rate?
The thicker your arteries, the more blood pressure it takes to pump it through.
If your arteries are clogged with blood vessels, it does not let as much blood flow by as originaly possible, so the body needs to push the blood through it harder, making your heart beat faster, therefore increasing your heart rate.
If your heart rate is high, it means that your heart is not working as hard to pump blood through your arteries. So it is healthier to have a higger heart rate than a lower one.

What is heart's electrical activity.?
The heart's electrical activity is generated by a specialized group of cells known as the sinoatrial (SA) node, often referred to as the heart's natural pacemaker. This activity initiates electrical impulses that cause the heart muscles to contract and pump blood. The impulses spread through the atria to the atrioventricular (AV) node, and then to the ventricles, coordinating the heartbeat. This electrical conduction system is crucial for maintaining a regular and efficient heart rhythm.
Why is a person heavier when faint?
A person is not heavier, but only less cooperative and harder to get a firm grip on. You can pick up a heavy sack, but it is much easier if it has some good handles.
What are some details about the implementation of zoom FFT in ultrasonic blood flow analysis?
Zoom FFT is a diagnostic tool for the detection of blood clots and other diseases. It is less costly than other techniques.
Zoom FFT uses a low frequency to measure blood flow in order to find clots. A transmitter passes an ultrasonic wave through the blood vessels. A reflected signal is passed to a DSP processor. (This is similar to the Doppler technique.) The process is achieved with one DSP chip in order to keep the costs lower.
How does the impulse to contract slow down slightly before it is transferred into the ventricles?
junctional fibers leading into the AV node have very small diameters
Is the tricuspid valve on left or right side of the heart?
The tricuspid valve is on the right side of the heart, connecting the right atrium and the right ventricle. The analogous valve on the left side of the heart is the mitral or bicuspid valve.
The Mitral Valve is in between the left atrium and the left ventricle of the heart. Oxygenated blood is pumped from left atrium to the left ventricle through that valve, mitral valve, then to the whole body through the Aorta artery. So problems with this valve may make the blood go back to the atrium during the contraction of the ventricle and this leads to decrease of the pressure of blood and the amount of it to the Aorta. This can affect the whole body.

How does a heart attack affect tissues and cells?
Heart attacks (myocardial infractions) cause tissues and the cells in part pf the heart to die. They actually block blood flow and that loss of blood will cause the cells and tissues to die. Some of these MIs are not large and scar tissue will form. But some are very large and the heart muscle will actually break apart causing death.
What is the contraction of the ventricles?
This would be ventricular tachycardia (tachy - fast, cardia - heart). This is a life-threatening medical emergency that requires immediate care.
