What is the main function of red blood cells?
Fight infections
Carry oxygen
Clot blood
Produce hormones
Which valve is located between the left atrium and the left ventricle?
Tricuspid valve
Pulmonary valve
Mitral (bicuspid) valve
Aortic valve
Which component of blood is primarily responsible for clotting?
Plasma
Red blood cells
Platelets
White blood cells
Which side of the heart pumps oxygenated blood to the body?
Right side
Left side
Both sides
Neither side
What is the correct order of blood flow through the heart starting from the right atrium?
Right atrium → Right ventricle → Pulmonary artery → Lungs → Left atrium → Left ventricle → Aorta
Right atrium → Left ventricle → Pulmonary vein → Lungs → Right ventricle → Left atrium → Aorta
Right atrium → Left atrium → Right ventricle → Left ventricle → Aorta → Lungs
Right atrium → Right ventricle → Aorta → Lungs → Left atrium → Left ventricle → Pulmonary artery
Which phase of the cardiac cycle involves the contraction of the ventricles?
Diastole
Systole
Resting phase
Repolarization
Which blood vessel carries oxygenated blood from the lungs to the heart?
Pulmonary artery
Pulmonary vein
Aorta
Superior vena cava
Which of the following best describes the function of heart valves?
To pump blood
To prevent backflow of blood
To oxygenate blood
To filter blood
Which component of blood helps defend the body against infection?
Red blood cells
Platelets
White blood cells
Plasma
If a patient has a faulty tricuspid valve, which part of the heart's blood flow is most directly affected?
Blood flow from right atrium to right ventricle
Blood flow from left atrium to left ventricle
Blood flow from right ventricle to pulmonary artery
Blood flow from left ventricle to aorta
During vigorous exercise, which chamber of the heart must work harder to supply oxygenated blood to the body?
Right atrium
Left ventricle
Right ventricle
Left atrium
If the pulmonary valve fails to close properly, what is the most likely consequence?
Blood will flow backward into the right ventricle
Blood will flow backward into the left ventricle
Blood will flow backward into the left atrium
Blood will flow backward into the right atrium
Which of the following best explains why the left ventricle has a thicker wall than the right ventricle?
It pumps blood a shorter distance
It pumps blood to the lungs
It pumps blood to the entire body
It receives blood from the lungs
A patient has a blockage in the pulmonary artery. Which of the following is the most immediate effect on blood flow?
Oxygenated blood cannot reach the body
Deoxygenated blood cannot reach the lungs
Oxygenated blood cannot reach the heart
Deoxygenated blood cannot reach the body
A person has a genetic disorder that reduces the number of platelets in their blood. What is the most likely symptom they will experience?
Increased risk of infection
Difficulty in blood clotting
Reduced oxygen transport
High blood pressure
A patient is found to have a hole between their right and left atria. How might this affect the oxygenation of their blood?
It would allow mixing of oxygenated and deoxygenated blood, reducing overall oxygen delivery to tissues
It would increase the efficiency of oxygenation
It would have no effect on oxygenation
It would only affect blood pressure, not oxygenation
A doctor hears a heart murmur caused by regurgitation through the mitral valve. What is the most likely direction of abnormal blood flow?
From left ventricle to left atrium during ventricular contraction
From left atrium to left ventricle during ventricular contraction
From right ventricle to right atrium during ventricular contraction
From right atrium to right ventricle during ventricular contraction
A patient is experiencing shortness of breath and fatigue. Tests reveal that their left ventricle is not pumping efficiently. Using your knowledge of cardiac anatomy and blood flow, which of the following is the most likely physiological consequence?
Blood backs up into the lungs, causing pulmonary congestion
Blood backs up into the body, causing systemic edema
Blood flow to the lungs increases
Blood flow to the right atrium increases
What helps blood flow forward through the veins?
This artery caries deoxygenated blood
(a)
What enzyme converts fibrinogen into fibrin
What is the official name for a blood pressure cuff?
(a)
