Heart Wall/Structure
The number of tissue layers that surround the heart
What is 3?
- When one or more of the heart valves do not open or close properly
- When it affects more than one heart valve, it is called multiple valvular heart disease.
When does heart valve disease occur?
The number of muscular chambers in the heart
What is 4?
fluid tissue of the cardiovascular system
What is blood?
controls flow between the right ventricle and the lungs
What is the pulmonary valve?
This muscle wall makes up most of the heart
What is the myocardium?
When the valve opening becomes narrow and restricts blood flow
What is stenosis?
The heart is this big
nutrients, oxygen, hormones/enzymes, removal of wastes, protection against disease and infection
What does blood provide to cells/tissue?
- Between the left atrium and the left ventricle
- It opens so the oxygen-rich blood from the left atrium can be pumped into the left ventricle
What is the mitral valve?
This muscle wall covers the outer surface of the heart
What is the epicardium?
When a valve slips out of place or the valve flaps (leaflets) do not close properly
What is prolapse?
The heart beat this many times in a day
What is approximately 100,000 times?
blood is this kind of tissue
Controls blood flow from the left ventricle into the aorta (the main artery in your body)
What is the aortic valve?
This muscle wall is the inner surface and includes heart valves
What is the endocardium?
When blood leaks backward through a valve, sometimes due to prolapse
What is regurgitation?
The thin, tough sac that covers the heart
What is the pericardium?
the 3 "formed elements" of blood
What are platelets, white blood cells, and red blood cells?
Between the right atrium and the right ventricle. It opens so blood can be pumped to the right ventricle.
What is the tricuspid valve?
fluid builds up here to cause Pericardial Tamponade What is the pericardial cavity?
What is the pericardial cavity?
What is an enlarged heart or heart failure?
serious condition that occurs when extra fluid or blood builds up in the space between the heart and pericardium
What is Pericardial Tamponade?
This will attack antigens on “foreign” RBCs
What are antibodies?
Calcification of the valve, congenital defects, and rheumatic fever.
What are the causes of heart valve disease?
