Does blood ever flow backwards in the heart?
Arteries have no valves to prevent the blood from flowing backwards, but it is unnecessary when the heart keeps pumping. The blood pressure is highest when the blood is leaving the heart chamber into arteries -- the heart pumping keeps blood going one-way in the arteries.
Which side of the heart contains oxygenated blood?
The left atrium and left ventricle contain the oxygenated blood.
the left side of the heart:D<3
left
the left side has arteries, which contain oxygenated blood.
left side
The left side, the right carries CO2 rich blood.
Right side
Which is stronger the heart or the brain?
The heart has beauty, potential. It is what holds everything you love, and hate. It holds the memories, the good times. It holds the people you love, the things you like. It holds your problems and your secrets. It is locked tight and your smile is the key. Your heart is strong if you can go on with life knowing that there are bad things ahead and behind. You have a strong heart if you can go through with anything and have pride in your soul! ~Jenn

Is the heart a tissue or an organ?
Yes
The heart is a muscle tissue - cardiac to be precise
Any living piece of an organism is a tissue
Tissue is a cellular organizational level intermediate between cells and a complete organism. A tissue is an ensemble of similar cells and from the same origin, that together carry out a specific function.
There are four main types of tissue:
connective
muscle
nervous
epithelial
There are three types of muscle:
smooth
skeletal
cardiac
What is the function of the Mitral valve?
a passage way from the left atrium to the left ventricle.
It prevents back flow of blood from the left ventricle to the left atrium.
prevents backflow of blood from the left ventricle into the left atrium.
What is the name of the vessel that brings blood to the heart?
The vessels that bring blood back to the heart are called the veins.
The vessel that brings blood back to the heart is the vein. The major blood vessels include the superior vena cava, inferior vena cava, the pulmonary artery and the pulmonary veins.
---- == == Vein
Blue blood...veins are the blood vessels that carry the oxygen-poor or blue blood from the body towards the heart.
If mitral valve does not close properly which circulation is affected?
The systemic - as the blood flow that travels through the mitral valve is the oxygenated blood meant for the tissues in the body.
What connects the heart to the lungs?
Your heart is placed in your thorax between your lungs. There is no anatomical connection between both except by way of pulmonary blood vessels. You have pulmonary arteries and pulmonary veins to connect the lungs with your heart.
Yes, and no. THE aorta is the bodies main artery that carries blood from the heart to the body. The aortic valve is a heart valve that, as you would expect, lies at the junction of the heart and the aorta. It prevents blood from flowing back into the heart once it has entered the aorta.
Which country pioneered heart transplant surgery?
A team led by Christiaan (this is the proper South African spelling, with two "a"s) Bernard performed the first successful human to human heart transplant in South Africa in 1967. The patient lived 18 days before succumbing to pneumonia.
An earlier unsuccessful transplant of a Chimpanzee heart into a dying human was performed by a team led by James D. Hardy in Mississippi, USA, in 1964 (the patient lived only 90 minutes). This was the first heart transplant involving a human.
Robert Koffler Jarvik (the previous answer posted here) performed the first artificial heart implant, not the first heart transplant.
What happens if your heart valve malfunctions?
If your valves are not working then your blood will flow in the wrong direction
Is 88 beats per minute a normal heart rate for a 37 year old male?
A normal heart rate for An Adult is 60-101 beats per minute. It is not far off normal but my advice would be to get it checked out, it can do no harm. There is a condition called Bradycardia which is a heart rate of less than 60 beats per minute so that should be checked out. Please be aware though that the beats per minute do vary greatly between people. Get it checked.
What do you feel to know that your heart is beating?
Without being patronising, you'd know if it wasn't! However, I am a heart patient and sometimes can't feel my heart beating in the same places as other people can because my beat gets weak and fast. The places for normal people are your radial pulse point and your carotid pulse point (one side at a time). If you have a stethoscope, the apical pulse (that's what I do right over my heart) is your actual heart beating, but you have to get used to how and where to listen.
Your heart, as a normal person, will always be beating, but it's always worth a visit to your doctor for a cadiac checkup, as it's a very important organ that you don't value until it goes wrong!
Ask me any more questions that you have...
What causes the heart not to rest properly?
The heat muscle does not need rest, it works from the time it forms (in the embryo) up until you die.
Why does salt cause heart problems?
Because it does! It's one of the many medical 'sacred cows' that must not be questioned. Studies have shown that people suffering from hypertension (which is linked to heart problems) can reduce their blood pressure by reducing their salt (sodium) intake. Other studies have suggested that raising the potassium intake to balance that of the sodium has the same beneficial effect.
Other studies have suggested that salt intake has no effect on people with normal blood pressure.
The 'carved in stone' dogma is that too much salt raises blood pressure, although no-one has come up with an answer as to HOW it does.
What is the valve that separates the right atrium from the left ventricle?
The atrioventricular vales separate the atria from the ventricles. The left AV valve is also known as the mitral valve, and the right is the tricuspid valve.
What organ must blood go through in order to come back to the heart oxygenated?
Your heart gives oxygen to blood cells, then those carry oxygen throughout your body, and when they reach your heart again, it refills them with oxygen.
How many atria does the human heart have?
The heart only has one aorta. The aorta is the body's main artery that connects the heart to the body. There is the pulmonary artery but this one only takes blood away from the heart to the lungs. This one aorta carries blood around the body in a circle((from the heart to all organs and back again)) and has extensions that supply each organ and tissue and cell with oxygen and nutrients.
What pumps blood round your body?
the heart pumps the blood around your body through blood vessels , the artery which pumps blood from the heart to the rest of the body and veins which pump blood from the organs back to the heart.
