Cardiovascular System Discovery Stations Assessment

What are the three major components of the cardiovascular system?

• atria, ventricles, valves
• arteries, capillaries, veins
• heart, blood vessels, blood
• aorta, superior vena cava, inferior vena cava

Where do arteries carry blood?

• toward the heart
• away from the heart
• between veins and capillaries
• to the superior and inferior vena cava

Capillaries are the smallest and thinnest blood vessels. How does their structure dictate their function?

• to minimize heat lost
• to maximize the exchange of materials
• to minimize blood loss in the event of a cut
• to maximize the oxygen-carrying capacity of hemoglobin

What structure is a sac that encloses the heart to protect it and anchor it in place?

• epicardium
• serous fluid
• pericardium
• myocardium

What muscular layer of the heart is responsible for the contractions that produce a heartbeat and pump blood through the body?

• epicardium
• pericardium
• myocardium
• endocardium

Which part of the heart has the thickest walls because it's contractions are responsible for pumping blood through the entire body?

• left atrium
• right atrium
• left ventricle
• right ventricle

What type of valve prevents blood from flowing back into the atria when the ventricles contract?

• atrioventricular valves
• pulmonary valves
• semilunar valves
• aortic valve

What is systemic circulation?

• The movement of blood from the heart to the body and back.
• The movement of blood from the heart to the lungs and back.
• The mjovement of blood from the heart to the heart muscle and back.

What is pulmonary circulation?

• The movement of blood from the heart to the body and back.
• The movement of blood from the heart to the lungs and back.
• The mjovement of blood from the heart to the heart muscle and back.

What is coronary circulation?

• The movement of blood from the heart to the body and back.
• The movement of blood from the heart to the lungs and back.
• The mjovement of blood from the heart to the heart muscle and back.
