Anatomy
Between the tunica externa and the tunica intima.
Where is the tunica media located?
Fluid congestion or inadequate blood flow.
What causes heart failure?
These carry blood away from the heart.
What are arteries?
Can lead to an enlarged heart or heart failure.
What is heart valve disease?
Left and right ventricular.
What are the two types of ejection fraction.
Becomes narrow and restricts blood flow compared to a healthy aortic valve.
What is stenosis?
When the enlarged ventricles fill with blood.
What is Systolic Dysfunction?
Transport both oxygenated and deoxygenated blood.
What are capillaries?
Controls blood flow between the right ventricle and the lungs.
What is the pulmonary valve?
Increases afterload.
What are hypertension, artherosclerosis, and vasoconstriction.
Where Diastolic heart failure is located.
Where is the right side of the heart?
When the stiff ventricles fill with less blood than normal.
What is Diastolic Dysfunction?
The pressure of blood on the walls of the arteries as it circulates through the body.
What is blood pressure?
When blood leaks backward through a valve.
What is regurgitation?
Increases the force of a heart contraction.
What are positive inotropes?
The thick wall between ventricles.
What is the Interventricular Septum?
When blood backs up and can't reach the heart and the heart muscle dies.
What is a heart attack?
What is 90 - 99 mm Hg?
The tricuspid valve, pulmonary valve, mitral valve, and aortic valve.
What are the four valves of the heart?
40-55%.
What percentage of ejection fraction signals low heart function?
The fluid under the pericardium.
What is Pericardial Tamponade?
When the heart can't pump to maintain blood flow to remove wastes.
What is Pitting Edema?
Measurement of blood pressure over 120.
What is Systolic blood pressure?
How often the valve closes in order to prevent blood from flowing backwards and mixing oxygen-poor and rich blood together.
What is in between each valve step?
How hard the myocardium needs to contract to remove blood from the ventricles.
What is contractility?
