Which circuit carries blood to and from the lungs to pick up oxygen and drop off carbon dioxide?

  1. The pulmonary circuit
  2. The systemic circuit
  3. The coronary circuit
  4. The hepatic circuit
Show answer and solution

Correct answer: A. The pulmonary circuit

1. Human circulation runs as two distinct but linked circuits. 2. The pulmonary circuit transports blood to and from the lungs, where it picks up oxygen and delivers carbon dioxide for exhalation. 3. The systemic circuit serves the rest of the body's tissues instead. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 19 "The Cardiovascular System: The Heart", section 19.1 Heart Anatomy_

The systemic circuit delivers oxygenated blood to which destination?

  1. Only the heart muscle
  2. Virtually all body tissues
  3. The lungs by themselves
  4. Just the brain and liver
Show answer and solution

Correct answer: B. Virtually all body tissues

1. After the lungs oxygenate the blood, it returns to the left side of the heart. 2. The systemic circuit then transports that oxygenated blood to virtually all of the tissues of the body. 3. It also returns relatively deoxygenated blood back to the heart. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 19 "The Cardiovascular System: The Heart", section 19.1 Heart Anatomy_

Why must the left ventricle generate much more pressure than the right?

  1. It is the only chamber with valves
  2. It pumps twice the volume of blood
  3. It drives the high-resistance systemic circuit
  4. It has to fill the lungs against gravity
Show answer and solution

Correct answer: C. It drives the high-resistance systemic circuit

1. Each ventricle serves a different circuit with a different resistance. 2. To pump blood into the long systemic circuit, the left ventricle must generate a great amount of pressure. 3. The right ventricle needs less, since the pulmonary circuit is shorter and offers less resistance. 4. Both ventricles move the same volume per beat, which rules out the volume answer. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 19 "The Cardiovascular System: The Heart", section 19.1 Heart Anatomy_
