Heart

No you don't have a heart inside your heart. The heart is made up of four chambers though. This is a short explanation about the heart.

The heart is a very important muscle that you can't live without it. It pumps blood through your body.

The heart is made up of 4 different parts that are called the chambers. The chambers are called Left atrium, Right atrium, Left ventricle and Right ventricle. The left atrium receives blood from the pulmonary-vein, and pumps it into the left-ventricle. The right atrium receives de-oxygenated blood from the superior and the inferior venae cavae and the coronary-sinus. The left ventricle receives oxygenated blood from the left-atrium via the mitral-valve, and pumps it into the aorta.

The walls of the ventricles of the heart aren't thinner than the atria, they are thicker.

This is because they require more power as they pump blood around the body, while the atria only pump blood the short distance into the ventricles. More muscular walls are therefore needed to provide this power which is why they are thicker.

The left ventricle is even thicker than the right ventricle as it requires a lot more power to pump blood all around the body. The right ventricle only pumps blood to the lungs.

The lungs lie lateral to the heart

It depends on the adult's age, and weight. If you Google it, you should find a few tables, or programs to calculate what your heart rate should be. Anyway, heart rate is not your main concern, as it varies from person to person, you should worry more about things like cholesterol.

The diaphragma isn't attached to the heart. It separates the thoracic cavity from the abdominal cavity.

The diaphragm separates the thoracic cavity (heart, lungs & ribs) from the abdominal cavity and performs an important function in respiration: as the diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs.

Your maximal heart rate is 220 - MINUS your age. In most human their MHR is about 200- 220 BPM. Maximal heart rate is the highest number of times per minuet that you heart could contract during maximal physical exersion. It is unlikely for your heart to go into Fibrillation at heart rates of 200 - 250 BPM. Fibrillation occurs at heart rates of 300- 600 BPM and can be causes by Heart disease Electrical shock Heart attacks Heart Arrhythmia

Blood courses along veins back towards the heart.

The veins have one way valves to prevent back flow.

Venous blood from below the heart drains into the inferior vena cava. Venous blood from above the heart drains into the superior vena cava. These empty into the right atrium.

Arteries, the largest of which is the Aorta. Arteries then split down into smaller blood vessels called arterioles and then smaller still into one-cell-thick vessels known as capillaries. These capillaries are where diffusion, movement of Oxygen from the blood vessels into the nearby tissue cells, occurs.

On my 1998 Buick the valve was located near the battery. Mine was damaged during a hurried winter battery change.

yes, it does pass because when the de oxygenated blood comes through the left atrium the through the valves then into the left ventricle and goes to the lungs the it gets oxygenated but the de oxygenated blood goes through the veins and the oxygenated blood goes through the arteries and the capillaries join the both back to the process when it goes to the lung it gets oxygenated and the it goes back into the right atrium after that through the other valves the into the right ventricle then it goes through a big pipe called the AYOTA that is the process of the heart.

the blood, blood vessels and the heart are the three main elements of the circularatory system.

Hope that helped :)

Fetal circulation enables the bypassing of the lungs via the foramen ovale. This shunt should close with the birth of the child. If this dose not happen the child will have what's called s patent foramen ovale. Other more serious ventricular sepatal defects may also occur that have to do with poor formation of the ventricular septum that separates the right and left ventricle.

It is important to keep your circulatory system working at its best. Your heart pumps blood to every part of your body. It travels through thousands of miles of blood vessels! Blood carries oxygen from your lungs. If there is a problem with your blood, your heart, or your blood vessels, your whole body can suffer. If you don't get enough oxygen to your brain, you might not be able to think clearly. If your stomach isn't getting enough oxygen, it might be hard for you to digest your food. If there is a problem with one of your blood vessels, blood could stop flowing to a part of your body. Without it, those cells could die.

2 What can you do to keep your circulatory system healthy? You can make sure that you are getting plenty of exercise. When you exercise, you heart beats faster. This makes your heart stronger. Your heart is a muscle. Just like the muscles in your arms and legs, your heart gets bigger and stronger the more that you use it. Exercise also helps to keep your blood vessels working properly. Go outside and play! Ride your bicycle. Go for a swim. Your body will thank you!

3 Eat healthy foods. They will keep your circulatory system healthy. Iron-rich foods like beans, whole-grain breads and cereals, red meat, and green vegetables are good for your blood. Try to avoid fatty foods, especially fried foods and foods that contain a type of fat called trans fat. Eating too much fat can cause fat

Atrial fibrillation and flutter are usually diagnosed through electrocardiography (EKGs), an exercise stress test, a 24-hour Holter EKG monitor, or a telephone cardiac monitor

Your lungs do not hold the heart. Heart is placed in the mediastinum between both the lungs. Two third part of the heart is on the left side of plane that passes from mid-line. So heart has more impression on the left lung as compared to right lung.

When blood supply to the heart is blocked what happens is a myocardial infarction which can result in death.

Leopards have a resting heart rate of 90 to 140 on average

Atrioventricular valves ar the valves in the heart that lie between the atria and the ventricles. These valves stop the the blood from flowing back (in the wtong direction) from the ventricles into the atria. There are two atrioventricular valves, on the right is the Tricuspis and on the left is the Bicuspid or Mitral valve.

Can you explain how it is also present in about 11% of patients with Marfan syndrome?

the septum seperates the left and right ventricles

the surgeon cuts the diseased valve away from the valve annulus (outer ring). The annulus is sized so that the proper size of valve can be selected for the patient's anatomy. Sutures are applied around the valve annulus, the valve is sutured into place
