What is the disorder called that results from blocked blood flow to the heart?
Cornary Artery Disease (CAD)
Does the brain need the heart to work?
Yes- The brain, like everything else in your body, needs oxygen, nutrients, and water which is brought to the brain by blood. There is no way the blood could get there without the heart.
What is more important the liver or the heart?
Both the heart and liver are vital to life, as is brain stem functioning. Humans can also live with damage to the heart or liver. But, it is harder to live with liver damage than to live with heart damage. The liver "detoxes" the entire body and is vital to process many of the medications ill persons must take to survive. But when the liver is damaged, it cannot process the toxins and by-products like a healthy liver can. Toxins build up in the blood stream until they begin to damage the brain and other organs.
Interestingly, though, one person can die from heart disease but have a relatively healthy liver.... while another person can die from liver ailments/damage while having a relatively strong heart!
But, while each are vital to life, I'd have to say the liver's 'health' is more important in both health and in chronic medical conditions.
What are signs of heart failure?
patient with Right sided heart failure usually presenting as having edema in the lower limb or if severe, they can have sacral edema. they also may present as having systemic or portal venous congestion, enlarged liver and spleen and also ascites.
What are 5 things that can go wrong with your heart?
Well lets see
1 heart murmur, [which i believe is a hole in the heart.
2 a heart attack.
3 to much blood being pumped
4 if the lungs fail, the heart is at risk/
5 if the heart stops you die.
Is it true that the two chambers at the bottom of your heart are called ventricles?
The left and right atria are the top chambers of the heart and the left and right ventricles are the bottom chambers of the heart. The aorta is the main artery leaving the heart to carry blood to the body.
What happens if your heart explodes literally?
Never underestimate you heart's potential to explode ... High doses of HDL can reduce your risk of heart disease by lowering your LDL level heart cannot explode but it is possible that vessels that can burst heart i overdose on a inhaler.Can my heart explode? Ans:Yes it can explode you are overweight there is a possible chance that you will have lots and lots of fat surrounding your heart and that means that here is a possible chance of heart fallier.
What are the 4 walls of the human heart?
Actually, the heart is surrounded by a pericardium and its wall is made of 3 layers. Therefore, the terminology "4 walls of the human heart" is quite misleading.
So, from outside to inside, we have:
*Pericardium
*Heart wall:
-Epicardium
-Myocardium
-Endocardium
How is a pig heart similar to a humans heart?
They are similar in size, anatomy, and function. They both have four chambers and four valves.
What are the bottom two chambers of the heart called?
They are the atria (atrium singular). There are two. They are above the ventricles, and are smaller. Their job is to pump the blood to the ventricles. There is a left and a right atrium, and each pumps to their same-side ventricle.
The term "auricle" was previously applied to an atrium, but now is used to identify a specific section of the chamber.
What is responsible for carrying blood away from the heart?
Arteries carry oxygenated blood away from the heart.
This is true in all cases except the pulmonary artery, which takes deoxygenated blood from the heart to the lungs.
Think of it this way: arteries take blood out of the heart, veins bring blood in.
What tissue Flows through the heart and blood vessels?
Connective tissue flows through the heart and blood vessels.
Does heart pump blood to arteries or veins?
The heart pumps blood through the arteries to all parts of the body. The blood is carried back to the heart through the veins.
There is an exception: The Pulmonary artery is the only artery that carries blood to the heart & and the Pulmonary Vein is the only vein that carries blood from the heart.
What nerves control the heart beat?
>Heart beats continuously and pumps blood.
>Heart is controlled by autonomous nervous system when brain isn't aware about it or is at rest.
>While the beats are regulated by medulla oblongata situated in hind brain.
>The two autonomous nervous system: Sympathetic and parasympathetic nervous system; act complimentorily and contradictorily which controls involuntary activities.
>For example, if the heart beat increases due to sympathetic nervous system than normal, it is brought under control and lowered by the action of parasympathetic nervous system.
Name the upper and lower chambers in the heart?
The lower (ventricles) are muscular and the valves can seal both openings.
The upper (atria) are significantly weaker and are not sealed at the venous portal.
Both left sides are thicker and stronger than the right (systemic pressure is much higher than pulmonary).
What are heart attacks associated with?
A heart attack is also referred to as a cardiovascular accident (CVA) or a myocardial infarction. There are many factors that can contribute to a person's risk of getting a heart attack. The list may include things like smoking, obesity, lack of exercise, high cholesterol diet, depression, family history, hypertension, predisposition, etc.
How many chambers are there in a pigs heart name them?
The four chambers of a pig's heart have the same names as the analogous chambers in a human heart: right atrium, right ventricle, left atrium, left ventricle.
The anatomy and physiology in pigs is very similar to a human's. Human biology studies often include a dissection of a fetal pig for lessons in anatomy. The pig's heart is one of the very similar organs to ours.
The names of the four chambers in a pig's heart are the same as the four chambers in our hearts: The Right and Left Ventricles and the Right and Left Atria (plural for atrium).
What part of the heart beat makes the heart beat sound?
The closure of the Mitral and tricuspid valves causes us to hear the first heart sound or S1 (M1T1) while the closure of the aortic and pulmonary valves allows us to hear the second heart sound or S2 (A2P2).
What happens if the AV node is damaged or non functional?
There is no coordination between the atria and the ventricles, and ventricular filling can become compromised.
