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.

The heart layer containing intercalated disks?
The layer of the heart containing intercalated disks is the myocardium. Myocardium is one of the tissues of the heart that is made of cardiac muscles.
What are the names of the two main sections of the heart?
The names of the two sides of the heart are the right heart and the left heart. The right heart is a low pressures pump that receives venous blood from the systemic circulation and pumps it to the lungs. The left heart is a high pressure pump which receives blood from the pulmonary veins and pumps it to the rest of the body via the aorta.
What is the main reason for a heart attack?
heart attacks are caused by the narrowing and thinkening of arteries.the arteries get narrowed and thinkned because of te deposition of cholestrol, fibrin, and cellular debris in the endothety of the arteries can lead to heart attack
some other reasons are high blood pressure,increased smoking and increased stress can alo cause heart attacksiugigwiy
Can a heroin overdose cause you to have a heart attack?
Heroin can cause a person to have a heart attack. Heroin is a drug that is bad.
What kind of circulation does the left side of the heart pump blood?
the oxygenated blood reaches the left atrium from the lungs. the contraction of the atria (atrial systole) increases the pressure in the atria such that it exceeds the ventricular pressure. the atioventricular valves then open. as we know liquid always moves from a region of high pressure to a region of low pressur. similarly in the heart blood will flow from the left atrium to the left ventricle.it will then be pumped into the systemic circulation.
When does the heart work hardest?
Your muscles work the hardest when you exerciser. This is because the strongest muscle (your heart) begins to pump blood around your body faster making your other muscles work faster too.
What happens if heart beat is more than 100 in a minute?
not sure of the spelling but i think it ventricular tachycardia
What brings blood from below the diaphragm to the heart?
The inferior vena cava brings blood from the lower parts of the body to the heart. The blood is deoxygenated.
What Is Between The Right Artium And Right Ventricle?
The partition between the sides of the heart is called the septum.
George Lippert, a sideshow freak who also had a third leg, was born with two hearts. This condition was unknown until the autopsy after his death from tuberculosis at age 62. One of the hearts had actually stopped working several weeks earlier but the other heart was able to sustain him (and would have continued to do so if it were not for the tuberculosis).

Where does blood floe from when it enters the tricuspid valve and passes into the right ventricle?
the tricuspid valve is between the right atrium and ventricle. deoxygenated blood from the superior and inferior vena cavae flows from the right atrium to right ventricle through this tricuspid valve. from there it goes to the lungs for oxygenation via the pulmonary artery.
What are the two chambers on the top called?
The two top chambers of the heart are called the right and left auricle respectively
Where does blood flow from when it passes through the semilunar valve and into the lungs?
Semilunar valves are found throughout the body in veins, as they prevent backflow of deoxygenated blood. In the heart, there are two semilunar valves, the pulmonary semilunar valve and the aortic semilunar valve. The pulmonary semilunar valve is the gateway to the pulmonary artery, which then goes to the lungs. The aortic semilunar valve is the gateway to the aorta, which distributes oxygenated blood to the rest of the body.
Does the left ventricle pump the same amount of blood as the right ventricle?
Yes, the left ventricle pumps throughout the entire body, but the right ventricle only goes to the lungs. Yes, the left ventricle pumps throughout the entire body, but the right ventricle only goes to the lungs.
Why is the ventricle of the frog's heart thicker and more muscular than the atria?
A ventricle's walls are thicker than those of the atrium because it needs to generate higher pressure. This higher pressure is needed to push blood into the circulation, while the atrium only needs to push blood into the ventricle.
What is the normal heart rate for an eighteen month old with a fever?
The average heart rate for a 2-year-old is anywhere from 80-130 beats per minute. This fluctuates between activity and rest.
Can you survive with a half of a heart?
No,A half heart does not have enough power to run the human body.
What does it mean when you're weak and your heart is racing?
It's called a cardiac palpitation and can be indicative of a variety of electroconduction problems in your cardiac (heart) conduction systems. Chances are its nothing to be worried about, but you should definitely schedule a meeting with a doctor and get referred to a cardiologist to see if you can get tested via ekg or a holter monitor to try and see what is going on: especially if you are pregnant as your categories suggest.
What chamber pumps blood out of the heart?
The left ventricle is the heart chamber that pumps blood throughout the body. The right ventricle, in contrast, pumps blood to the lungs.
