Heart Flashcards
Name the pathway of blood flow through the heart and circulatory system?
- Inferior & superior vena cava
- right atrium
- tricuspid valve
- right ventricle
- pulmonary veins
- lungs
- pulmonary artery
- pulmonary valve
- left atrium
- mitral valve
- left ventricle
- aortic valve
- aorta
Briefly describe the heart wall?
– Has 3 layers (epicardium, myocardium, endocardium)
– Epicardium is the outer protective layer
–Myocardium is the thick middle layer
– Endocardium is the inner layer
What is the function of the Heart/Cardiovascular system?
pump blood and deliver oxygen and nutrients to all the body’s cells
Where is the heart located?
in the mediastinum, to the left of the sternum
Name the heart valves and indicate their locations
– Tricuspid valve – located between right atrium and right ventricle
– Pulmonary valve – located between right ventricle and pulmonary artery
– Mitral valve – located between the left atrium and left ventricle
– Aortic valve – located between the left ventricle and aorta
Discuss what causes the heart sounds and how to distinguish them?
– Heart sounds are caused by turbulence associated with closing of the heart valves
– using a stethoscope
Which two circulatory systems does the heart pump blood through?
- Lungs
- Tissues & Organs
Which side of the heart forms the Pulmonary circulatory?
- Right side
Which side of the forms the systemic circulation?
- Left side
Arteries carry ___
- Oxygenated blood AWAY from the heart
Veins carry ___
- Deoxygenated blood TOWARDS the heart
Name the chambers of the heart?
- Right Atria
- Right Ventricle
- Left Atria
- Left Ventricle
What side of the heart receives DEOXYGENATED BLOOD?
- Right Side
What side of the heart receives OXYGENATED BLOOD?
- Left side
What is the Right atrioventricular valve called?
- Tricuspid valve
What is the Left atrioventricular valve called?
- Bicuspid
Heart Failure is __
- When the heart muscle doesn’t pump enough blood for the body’s need
What are the primary causes of Heart Failure?
- Coronary Artery disease
- Hypertension
- Rheumatic Heart Disease
- Congenital Heart Defects
Describe Systolic failure?
- When the heart isn’t contracting well
Describe Diastolic failure?
- When the heart cannot relax normally
Describe Left-sided HF?
- The left ventricle of the heart no longer pumps enough blood around the body
Describe Right-sided HF?
- When the Right ventricle fails to contract effectively
What occurs during ‘lub’ AKA S1?
- Closure of the ATRIOVENTRICULAR VALVES
What occurs during ‘DUB’ AKA S2?
- Closure of the SEMILUNAR VALVES
