Cardiovascular System Worksheet

Which component of blood is primarily responsible for oxygen transport?

• Red Blood Cells (Erythrocytes)

• White Blood Cells (Leukocytes)

• Platelets (Thrombocytes)

• Plasma

Which blood component is involved in blood clotting?

• Red Blood Cells (Erythrocytes)

• White Blood Cells (Leukocytes)

• Platelets (Thrombocytes)

• Plasma

A patient is found to have a deficiency in platelets. Which of the following symptoms are they most likely to experience?

• Difficulty fighting infections

• Problems with oxygen transport

• Issues with blood clotting

• Reduced nutrient transport

If a person’s blood volume is significantly reduced, which of the following body functions would be most directly affected?

• Oxygen transport, immune defense, and nutrient delivery

• Vision and hearing

• Bone growth and repair

• Muscle contraction only

Which type of blood vessel carries blood away from the heart?

• Arteries

• Veins

• Capillaries

• Lymph nodes

What is the main function of capillaries in the circulatory system?

• Carry blood away from the heart

• Return blood to the heart

• Site of nutrient/gas exchange

• Handle high pressure

Which of the following is true about veins?

• They handle high pressure

• They contain valves

• They have thick, elastic walls

• They are single cell thick

Which blood vessel brings deoxygenated blood from the body into the right atrium of the heart?

• Pulmonary vein

• Aorta

• Superior/inferior vena cava

• Pulmonary artery

What is the correct order of blood flow starting from the right atrium?

• Right atrium → Right ventricle → Pulmonary artery → Lungs → Pulmonary veins → Left atrium → Left ventricle → Aorta

• Right atrium → Pulmonary artery → Right ventricle → Lungs → Pulmonary veins → Left atrium → Left ventricle → Aorta

• Right atrium → Left ventricle → Pulmonary artery → Lungs → Pulmonary veins → Right ventricle → Left atrium → Aorta

• Right atrium → Right ventricle → Pulmonary veins → Lungs → Pulmonary artery → Left atrium → Left ventricle → Aorta

After blood leaves the left ventricle, where does it go next?

• Pulmonary artery

• Aorta

• Right atrium

• Pulmonary veins
