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.

Can you have a heart attack while dreaming?
A heart attack is painful and will be noticed, but it will not necessarily be understood. Many people who have heart attacks think that they have had an attack of indigestion, or some other minor illness.
What part of the blood is atria and ventricles?
The Atria and Ventricles are parts of the heart not the blood. The Atria is the upper chambers of the heart and the Ventricles are the lower chambers of the heart.
Deoxygenated blood from the body first enters the of the heart?
The right atrium is where deoxygenated blood enters the heart.
What is the coronary artery disease?
Coronary heart disease refers to the failure of coronary circulation to supply adequate circulation to cardiac muscle and surrounding tissue. Coronary heart disease is the most common form of disease affecting the heart and an important cause of premature death. It's predicted that coronary heart disease will affect all the regions of the world by 2020.
What is the pumping tissue of the heart called?
atrial and ventricular systole occur at the same time
What can cause the heart to enlarge and weaken?
Here you go:
Chronic disease of the heart muscle
High blood pressure- A chronic medical condition in which the blood pressure is elevated. it is also referred to as high blood pressure or shortened to ht, htn or hpn. the word "hypertension", by itself, normally refers to systemic, arterial hypertension.
Cardiomegaly- Abnormal enlargement of the heart
Hypertrophic cardiomyopathy- A disease of the myocardium in which a portion of the myocardium is hypertrophied without any obvious cause. it is perhaps most famous as a leading cause of sudden cardiac death in young athletes.
Heart valve disease- Any disease process involving one or more of the valves of the heart. valve problems may be congenital or acquired.
Where does oxygenated blood enter the heart?
Through the inferior and superior vena cava
The left atria of the heart is where oxygenated blood enters, it is then pumped to the left ventricle and then to the rest of the body thru the systematic circuit. The heart is separated by the septum, which separates oxygenated and deoxygenated blood.
What valves separate the chambers of the heart?
1)Tricuspid valve separates the right atrium from the right ventricle
2) Pulmonary (semilunar) valve separates the right ventricle from the pulmonary trunk leading to the pulmonary arteries
3) Bicuspid (Mitral) valve separates the left atrium from the left ventricle
4) Aortic valve separates the left ventricle from the aorta
Is it possible to get a heart attack at fifteen?
Absolutely!
While typically people do not develop heart disease until much older, age is not the only risk factor for heart disease. Obesity, high blood sugar, high blood pressure, and high cholesterol can trump age. Sadly, the epidemic of childhood obesity and the health issues associated with it such as diabetes, is increasing the number of children developing heart disease.
The good news, however, is the risk and impact of heart disease can be reduced through good eating habits, increased activity, and careful monitoring and control of blood pressure, cholesterol, and blood sugar.
Yes they can.The more common condition to affect kids and young adults that can lead to them dropping dead during physical activity, is called hypertrophic cardiomyopathy (HCM). It is the leading cause of sudden cardiac death in adolescent children.
What regulates blood flow to tissue and blood pressure?
Asians help your blood flow everyone knows that
Who has more heart attacks men or women?
Women. Often when they go to the ER the heart attack is not identified as one, but something else.
Which chamber of the heart does the vena cava enter into?
The cranial and caudal vena cava open in the right atrium.
What are the hearts two atrioventricular valves and two semilunar valves?
Tricuspid valve has three flaps and it is located between the right auricle and right ventricle. It prevents the blood from flowing back into the auricle.
The mitral or bicuspid valve is situated between left auricle and left ventricle. It has two flaps which help in maintaining the blood flow in one direction (from left auricle to left ventricle). Tricuspid and bicuspid valves are together called auriculo-ventriclar valves.
Semilunar valves has flap which resembles half moon. Pulmonary semilunar valve keep the direction of blood flow from right ventricle to lungs and aortic semilunar valve keep the direction of blood flow from left ventricle to aorta.
Oxygenated blood enters the heart at the?
Oxygen-poor blood from the body enters the heart from two large blood vessels, the inferior vena cava and the superior vena cava, and collects in the right atrium.
ok for a school report that's not doing any good
Identify the vessel that conducts blood from the left ventricle?
The Aorta (the aortic arch)
The left ventricle of the human body contains oxygenated blood. This oxygenated blood is pumped to all parts of the body except the lungs. Hence the left ventricle which has a thick cardiac wall pumps blood through aorta, the main artery, which is the only blood vessel that arises from the left ventricle.
Left atrium--------> Left ventricle ----------> Aorta
Im not a doctor but that sounds a lot like a heart attack.
When can an ultra sound detect a fetus heart beat?
Around the 6 weeks point of pregnancy. However not all Dr's will tell you what it is unless you ask.
No such thing
Blood pressure (BP) is the pressure (force per unit area) exerted by circulating blood on the walls of blood vessels, and constitutes one of the principal vital signs. The pressure of the circulating blood decreases as it moves away from the heart through arteries and capillaries, and toward the heart through veins.
How blood circulates through the body?
Let's start with deoxygenated blood at the heart. It enters the right atrium of the heart, then passes into the right ventricle. From here, it is pumped to the lungs where gaseous exchange takes place. After this, it returns to heart, the left atrium this time. It passes into the left ventricle and is pumped to all the other organs in the body. The deoxygenated blood returns to the heart to complete the circuit.
