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 causes extra fluid in the pericardial cavity?
The pericardial cavity or sac is the potential space between the parietal and visceral layers of serous pericardium. In other words, two different layers of cardiac tissue. It contains a thin film of serous fluid to provide a frictionless environment for the heart to beat freely.
When do you know when your heart is bad?
when it stops beating
=================
If it doesn't go "pitter-patter" when you see your love, there's something wrong with it.
Bad heart is a favorite complaint of hypochrondiacs , me included. But it still goes pitter-patter and that's ok enough for me
==================
What is the The upper part of the heart is called?
The upper quadrants of the heart are called atria. The right atrium receives the deoxygenated blood that has been circulated throughout the body. This blood then moves through the right ventricle and to the lungs to be oxygenated. This blood then returns to the left atrium, goes through the left ventricle, and into the aorta. The aorta then branches off and circulates through the entire body to bring oxygen to the cells and tissues.
What is stronger heart or brain?
The heart pumps blood to the brian, therefore the heart is stronger.
The previous answer is correct and incorrect at the same time (not just the misspelling of "brain"), as the question could have 2 meanings. If asking about physical strength, the heart will always win as it is almost solid muscle, constantly working every day you live.
The brain however wins hands-down as far as electrical current and "piston firing" is concerned. I don't think anyone has ever solved an equation or or written a screenplay with their physical heart.
What type of regurgitation causes backflow of blood from the left ventricle into the left atrium?
Mitral regurgitation
What department that performs diagnostic tests that relate to the heart and lungs?
depends on the lung test needed. go see a pulmonologist (lung dr) because the test may need to be done by radiology or nuclear medicine (x-ray or MRI). The dr may be able to do it in his office.
What is the process that your heart goes through?
the first step is after delivery to cells the blood is oxygen-poor.
the last step is the blood is sent to all regions of the body to deliver the oxygen to the cells. thats all i know sorry! hope this helps!
Which side of the heart pumps oxygen rich blood to the body !?
The left ventricle pumps blood to the body. It is rich in oxygen.
How many flaps does the aortic valve have?
The antrioventricular valve has two valves. The bicuspid valve has 2 flaps and in located in the right ventricle/right atrium. The tricuspid valve has 3 flaps and is located in the left ventricle/left atrium.
Where are the atria located What is their function and characteristics?
it is located in the heart
The Atria (plural) or Atrium (singular) are the chambers located in the top of the heart. Below the Atria are the Ventricles.
There are two atria in the heart, the left atrium and the right atrium.
Atria are located in the heart.
When the heart contracts what receives its blood supply?
Blood pressure is the force of blood against the inner walls of arterial blood vessels. Blood pressure rises when the ventricles contract and falls when the ventricles relax. Systolic pressure is the maximum pressure and diastolic pressure is the minimum pressure.
Where does the blood go next after it goes to the right atrium?
In the mammalian (and avian) heart, blood passes directly from the atria into the corresponding ventricles. So blood from the right atrium next enters the right ventricle.
First Aid treatment for heart attack?
To perform CPR (cardiopulmonary resuscitation) and artificial respiration (mouth to mouth resuscitation) effectively, training and frequent practice on resuscitation dummies are essential.
If the person is unconscious:
- are they breathing? Look at the patient's chest to see if it is rising and falling.
- do they have a pulse? Place two fingers on one or other side of the person's voice box in their throat to feel if they have a carotid pulse.
If the patient has a pulse but is not breathing:
- could it be because of suffocation? Feel inside the mouth with a finger to see if there is anything blocking it or the windpipe and remove any food or other objects. Provided that dentures are not broken, it is better not to remove them.
- call for help immediately, stating that the casualty is not breathing, and provide resuscitation (see below) until the patient begins to breathe or the ambulance arrives.
- If possible, raise the legs up 12 to 18 inches to allow more blood to flow towards the heart
- Immediately place the palm of your hand flat on the patient's chest just over the lower part of the sternum (breast bone) and press your hand in a pumping motion once or twice by using the other hand. This may make the heart beat again.
If these actions do not restore a pulse or if the subject doesn't begin to breathe again:
- call for help, stating that the casualty is having a cardiac arrest but stay with the patient.
- find out if any one else present knows CPR.
- provide artificial respiration immediately (see below).
- begin CPR immediately (see below).
- If possible, raise the legs up 12 to 18 inches to allow more blood to flow towards the heart
- Immediately place the palm of your hand flat on the patient's chest just over the lower part of the sternum (breast bone) and press your hand in a pumping motion once or twice by using the other hand. This may make the heart beat again.
Tilt the head back and lift up the chin.
- Pinch the nostrils shut with two fingers to prevent leakage of air.
- Take a deep breath and seal your own mouth over the person's mouth.
- Breathe slowly into the person's mouth - it should take about two seconds to adequately inflate the chest.
- Do this twice.
- Check to see if the chest rises as you breathe into the patient.
- If it does, enough air is being blown in.
- If there is resistance, try to hold the head back further and lift the chin again.
- Repeat this procedure until help arrives or the person starts breathing again
See if there is breathing. If not, start artificial respiration as described above. Checking for a pulse in the neck (carotid artery) may waste valuable time if the rescuer is inexperienced in this check. The procedure is:
- place your fingers in the groove between the windpipe and the muscles of the side of the neck. Press backwards here to check for a pulse.
If there is no pulse, or if you are unsure, then proceed without delay thus:
- look at the person's chest and find the 'upside-down V' shaped notch that is made by the lower edge of the ribcage. Place your middle finger in this notch and then place your index finger beside it, resting on the breastbone. Take the heel of your other hand and slide it down the breastbone until it is touching this index finger. The heel of your hand should now be positioned on the middle of the lower half of the breastbone.
- now place the heel of your other hand on top of the first. Keep your fingers off the chest, by locking them together. Your pressure should be applied through the heels of the hands only.
- keep your elbows straight, and bring your body weight over your hands to make it easier to press down.
- press down firmly and quickly to achieve a downwards movement of 4 to 5cm, then relax and repeat the compression.
- do this 15 times, then give artificial respiration twice, and continue this 15:2 procedure until help arrives.
- aim for a rate of compression of about 100 per minute. You can help your timing and counting by saying out loud 'one and two and three and four ...' etc.
- If possible, get someone else to help - one person to perform artificial respiration and the other to perform CPR. (This is not easily done without prior practice and it is well worth attending sessions on CPR training to become familiar with the technique.)
- The ratio of chest compressions to breaths is 15:2 for both one-person and two-person CPR.
- Continue until the ambulance arrives or the patient gets a pulse and starts to breathe again.
- If the pulse returns and breathing begins but the person remains unconscious, roll them gently onto their side into the recovery position. This way mucus or vomit can get out of the mouth and will not obstruct the patient's breathing. It also prevents the tongue from falling back and blocking the air passage.
- If you succeed in resuscitating the person who has been taken ill, he or she may be confused and alarmed by all the commotion. Keep the patient warm and calm by quietly, but clearly, telling them what has happened.
Again, it needs to be emphasised that the only way to provide proper first aid and resuscitation is through learning the technique, then regular practice and guidance.
What does the beating sound of your heart come from?
The sound of a heart beat is caused by the closing of the valves in the heart.
How many compartments does the heart have and what are they called?
There are four and two are called artiries and the other are called atries
Intial Effect: The Right Atrium cannot allow deoxygenated blood to pass through Pulmonary Artery and lack of oxygen circulation through the body will have dire consequences. Eventually, the Right Atrium will get overflown with blood and will explode, resulting in death.
