1. What is the primary function of capillaries in the circulatory system?
Storage of blood cells
Regulation of blood pressure
Transport of blood from the heart
Exchange of oxygen, nutrients, and waste
2. Describe the physiological impact of mitral valve prolapse on the heart's
function during systole.
Mitral valve prolapse increases the heart rate significantly.
Mitral valve prolapse causes the heart to pump more efficiently.
Mitral valve prolapse has no significant effect on heart function.
Mitral valve prolapse leads to improper closure of the mitral valve,
which can result in regurgitation of blood into the left atrium during
systole.
3. What is "transposition of the great vessels"?
a condition where the walls of the capillaries are too thick to allow
oxygen to be delivered to the tissues resulting in oxygen-starved
tissues
a condition where the arteries of the heart are switched resulting in
two separate circulatory loops and a lack of oxygen in the body
,tissues.
a condition where the blood flows from the right atrium to the left
atrium resulting in blood flowing backwards through the circulatory
system
,4. What is an electrocardiogram (ECG)?
A test that measures the electrical activity of the muscles.
A test that measures the electrical activity of the kidneys.
A test that measures the electrical activity of the heart.
A test that measures the electrical activity of the brain.
5. If a patient with mitral stenosis experiences severe symptoms, what could be
a potential consequence of untreated condition?
Improved oxygenation
Enhanced athletic performance
Increased blood pressure
Heart failure
6. What is the purpose of deploying a stent during cardiac catheterization
procedure?
to reinforce a narrowed artery and restore blood flow
to deliver medication directly to the heart
to remove cholesterol buildup from arteries
to record electrical signals from the heart
7. Describe the role of capillaries in the circulatory system.
Capillaries are responsible for heart contractions.
Capillaries carry blood away from the heart.
Capillaries facilitate the exchange of oxygen, nutrients, and waste
between blood and tissues.
, Capillaries store blood for later use.
8. Ventricular fibrillation is a life-threatening arrhythmia that necessitates:
Immediate administration of beta-blockers
Immediate administration of anticoagulants
Immediate administration of oxygen therapy
Immediate defibrillation to restore normal rhythm
9. Internal respiration:
Involves exchange of oxygen and carbon dioxide between the
blood and body cells
Involves movement of oxygen between the lungs and tissues by
blood
Involves exchange of oxygen and carbon dioxide between the blood
and the air in the alveoli
Involves movement of air into and out of lungs
10. Describe what heart murmurs indicate about the condition of the heart.
Heart murmurs indicate the presence of abnormal blood flow,
often due to structural defects or valve issues.
Heart murmurs indicate that the heart is beating too slowly.
Heart murmurs are unrelated to blood flow.
Heart murmurs are always a sign of a healthy heart.
11. What is the primary role of the tricuspid valve in the heart?
Facilitates gas exchange in the lungs
