Well the heart is based on 4 chambers you have 2 upper ventricals and 2 lower ventricles the ventricles each have 2 little doors that open and close. the top right ventricle will suck in the blood and the bottom 2 will transfer it to the left top ventricle which than pushes the blood out into the blood stream again in average healty heart will beat 70-75 beats per minute. Children have a higher rate in the 80's and 90's, depending on their age. The younger they are the faster the heart rate.
What is the name of the valve at the end of the esophagus?
A band of muscles at the opening of the stomach called the Cardiac (due to its proximity to the heart) Sphincter.
What is the medical term meaning Inflammation of the membrane surrounding the heart?
peri-around card-heart itis-inflammation pericarditis. endo-inside, endocarditis, inflammation inside the heart myo-muscle, myocarditis, inflammation of heart muscle
Pericarditis
What parts of the heart pump blood into the ventricles?
It flows through the atrioventricular (AV) valves. The right AV valve is the tricuspid valve, and the left AV valve is the bicuspid or mitral valve.
How does the heart compensate for changes in peripheral resistance?
Bleeding, technically known as hemorrhaging or haemorrhaging (see American and British spelling differences) is the loss of blood or blood escape from the circulatory system.[1] Bleeding can occur internally, where blood leaks from blood vessels inside the body or externally, either through a natural opening such as the vagina, mouth, nose, ear or anus, or through a break in the skin. The complete loss of blood is referred to as exsanguination,[2] and desanguination is a massive blood loss. Typically, a healthy person can endure a loss of 10-15% of the total blood volume without serious medical difficulties, and blood donation typically takes 8-10% of the donor's blood volume
How does the skeleton protect your heart and lungs?
The ribs are strong and makes your heart and lungs un hurtable
What is the medial partition between the lateral ventricles?
The interventricular septum is the medial partition between the lateral ventricles. It separates the oxygenated and deoxygenated blood.

Valves are made from metals, including brass, bronze, iron, steel, and alloys, as well as from plastics.
Where does the blood entering the Inferior vena cava come from?
The blood entering the Inferior Vena Cava comes from all your lower body areas... Legs, feet, ect.
Do you bleed from the mouth during a heart attack?
Not from the heart attack itself. In a heart attack, the heart is deprived of oxygen from the blockage of a coronary artery. This does not usually cause bleeding, but it does cause the death of the muscle cells if they don't get oxygen.
What is the transparent tissue that covers the heart called?
The pericardium.
It is composed of two layers: the fibrous pericardium (the outer layer that is made of tough connective tissue) and the serous pericardium (the inner layer in which serous fluid provides lubrication for the heart to beat with almost no friction).
What 2 jobs do the valves of the heart do?
Both AV valves, the bicuspid and tricuspid, (separating the ventricles from the atria) prevent blood from flowing back into the atria when the ventricles contract. Both the semilunar valves (separating the arteries from the ventricles) prevent blood from flowing back from the arteries once it has been pumped out of he ventricles, and thus, out of the heart. The difference is that the AV valves are contracted when they are CLOSED, but the semilunar valves are contracted when OPEN. Otherwise, I can't think of another major job besides preventing backflow.
What are the disadvantages if you have heart disease?
Chlorpromazine is not for use in psychotic conditions related to dementia. Chlorpromazine may cause heart failure, sudden death, or pneumonia in older adults with dementia-related conditions. You should not use this medication if you are allergic to chlorpromazine, or if you are also using large amounts of alcohol or medicines that make you sleepy. Before you take chlorpromazine, tell your doctor if you have liver or kidney disease, heart disease or high blood pressure, glaucoma, a breathing disorder, any type of cancer, an enlarged prostate, blockage in your intestines, seizures, a brain tumor, or Parkinson's disease. Tell your doctor if you will be exposed to extreme heat or to insecticide poisons while you are taking chlorpromazine. Chlorpromazine can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

It can increase some of the side effects of chlorpromazine. Avoid exposure to sunlight, sunlamps, or tanning beds. Chlorpromazine can make your skin more sensitive to sunlight, and a sunburn may result. Chlorpromazine is in a group of drugs called phenothiazines (FEEN-oh-THYE-zeens). It works by changing the actions of chemicals in your brain. Chlorpromazine is used to treat psychotic disorders such as schizophrenia or manic-depression, and severe behavioral problems in children. It is also used to treat nausea and vomiting, anxiety before surgery, chronic hiccups, and acute intermittent porphyria. Chlorpromazine may also be used for other purposes not listed in this medication guide.

It allows blood to pass from the inferior vena cava to the aorta without ultilizing the lungs, since fetuses can't breath. If you had this is an adult heart, you would suffocate as you would not be able to use your lungs and you wouldn't be receiving oxygen from your mother.
Why the left heart called pressure pump?
Your right ventricle pumps blood to your lungs. So the same is called as lung pump.
Where are the two valves in the heart?
There are actually four valves in the human heart. The heart has four chambers. The upper two are the right and left atria. The lower two are the right and left ventricles. Blood is pumped through the chambers, aided by four heart valves. The valves open and close to let the blood flow in only one direction.
-The tricuspid valve is between the right atrium and right ventricle.
-The pulmonary or pulmonic valve is between the right ventricle and the pulmonary artery.
-The mitral valve is between the left atrium and left ventricle.
-The aortic valve is between the left ventricle and the aorta.
Each valve has a set of flaps (also called leaflets or cusps). When working properly, the heart valves open and close fully.
What happens to you after you have a heart attack?
During a heart attack, part of your heart starts dying fast, caused by no oxygen, the quicker you seek help the less that dies. So a heart after a heart attack with-out quick medical attention will be partly dead and black, and the rest of the heart will have to work harder to make up for it the rest of the time the person is alive.
Sometimes the rest of the heart can NOT work hard enough to make up for the dead areas of the heart. This will cause the person's heart'd ejection fraction to be lower and may cause the person to have congestive heart failure and die or cause them to have a heart transplant.

How can body temperature influence the heart rate?
There is a direct correlation between heart rate and temperature. An increase in temperature, from normal, causes heart rate to increase. A decrease in temperature, from normal, causes heart rate to decrease.
>>That is not completely true. For A science fair project i tested this and we found that in extremes of hot and cold climates our heart rate increased both times
Describe the position and role of the valves in the heart?
There are 4 valves in the heart. The first valve though which the blood passes is the tricuspid which is one of the atrioventriculars (between a ventricle and an atrium) and stops backflow of blood from the right ventricle tothe right atrium. The next valve is the pulmonary valve, one of the semilunars, which stops backflow form the pulmonary artery to the right ventricle. The third valve is the mitral or bicuspid which (the other atrioventricular) which stops backflow from the left ventricle to the left atrium. The last valve is the aortic valve (the other semilunar) which stops backflow from the aorta to the left ventricel.
Most people can hear two heart sounds per cycle - a quiet "lub" and a louder "dub". The "lub" sound is the contraction of the two atria, which results in the ventricles being filled with blood. The "dub" sound is the contraction of the two ventricles, which results in blood being forced into the arterial system. However, a trained physician can hear four sounds - the two described above, and two more that represent the sound of the valves opening back up after the contraction is over.
What does grossly unremarkable-sized heart mean?
When a heart is looked at without using a microscope, the term grossly is used. It was not unusual in anyway (unremarkable). Looking at the heart, everything seems fine. But looking with a microscope may show some thing else.
How do the lungs and heart transport oxygen in the cardio respiratory system?
The lungs hold air that is breathed in. Oxygen gas in the air moves into the blood. The heart pumps to transports this oxygenated blood to cells in the body that need it to produce energy.
What happens if you take nitro when you aren't having a heart attack?
Nitro pills normally give you a bad headache even if you are having a heart attack.
