Course: Cardiology > Section: Module2

Q: What is the primary function of the cardiovascular system?
- To digest food
- To transport nutrients, gases, hormones, and waste products
- To regulate body temperature
- To produce hormones
A: To transport nutrients, gases, hormones, and waste products

Q: Where is the heart located in the human body?
- In the abdominal cavity
- In the thoracic cavity
- In the cranial cavity
- In the pelvic cavity
A: In the thoracic cavity

Q: Which chamber of the heart receives deoxygenated blood from the body?
- Left atrium
- Right atrium
- Left ventricle
- Right ventricle
A: Right atrium

Q: What is the largest artery in the body?
- Pulmonary artery
- Coronary artery
- Aorta
- Femoral artery
A: Aorta

Q: How do capillaries facilitate the exchange of substances?
- By pumping blood
- By filtering blood
- By allowing direct contact between blood and tissues
- By storing blood
A: By allowing direct contact between blood and tissues

Q: Why is understanding coronary circulation important?
- It helps in understanding the digestive system
- It is critical for recognizing blockages that can lead to heart conditions
- It is not important for cardiovascular health
- It only pertains to lung function
A: It is critical for recognizing blockages that can lead to heart conditions

Q: Which valves prevent backflow of blood into the heart after contraction?
- Atrioventricular valves
- Semilunar valves
- Coronary valves
- Pulmonary valves
A: Semilunar valves

Q: What role do the atrioventricular valves play in the heart?
- They separate the atria from the ventricles
- They connect the heart to the lungs
- They pump blood out of the heart
- They regulate blood pressure
A: They separate the atria from the ventricles

Q: How does the structure of arteries differ from that of veins?
- Arteries have thicker walls and are more muscular
- Veins have thicker walls and are more muscular
- Both have the same structure
- Arteries are smaller in diameter than veins
A: Arteries have thicker walls and are more muscular

Q: What is the primary function of the pericardium?
- To pump blood
- To protect and anchor the heart
- To supply blood to the heart
- To regulate heart rate
A: To protect and anchor the heart

Q: Which of the following factors can impact cardiovascular health?
- Diet
- Exercise
- Smoking
- All of the above
A: All of the above

Q: How does the heart's electrical conduction system contribute to its function?
- It provides oxygen to the heart
- It coordinates the contraction of the heart muscle
- It filters blood
- It produces hormones
A: It coordinates the contraction of the heart muscle

Q: What is the role of the sinoatrial (SA) node in the heart?
- To receive blood from the body
- To initiate the electrical impulse for the heartbeat
- To pump blood to the lungs
- To prevent backflow of blood
A: To initiate the electrical impulse for the heartbeat

Q: Why is it important for students to engage in hands-on activities related to the cardiovascular system?
- To memorize facts
- To enhance understanding of spatial relationships between structures
- To prepare for a test
- To learn about other body systems
A: To enhance understanding of spatial relationships between structures

Q: Which type of blood vessel is primarily responsible for gas exchange?
- Arteries
- Veins
- Capillaries
- Aorta
A: Capillaries

Q: What happens to blood flow during vasoconstriction?
- Blood flow increases
- Blood flow decreases
- Blood flow remains the same
- Blood flow reverses
A: Blood flow decreases

Q: How does the structure of the myocardium contribute to heart function?
- It provides a protective layer
- It allows for rapid transmission of electrical impulses
- It stores blood
- It regulates blood pressure
A: It allows for rapid transmission of electrical impulses

Q: What is a potential consequence of blockages in coronary arteries?
- Improved heart function
- Angina or myocardial infarction
- Increased oxygen supply
- Enhanced blood flow
A: Angina or myocardial infarction

Q: How can lifestyle choices affect the risk of developing coronary artery disease?
- They have no impact
- They can significantly influence risk factors
- They only affect blood pressure
- They only impact diet
A: They can significantly influence risk factors

Q: What is the significance of the pericardial cavity?
- It stores blood
- It allows for the exchange of gases
- It reduces friction during heartbeats
- It pumps blood
A: It reduces friction during heartbeats
