Worked practice questions

The heart sits between the lungs in the thoracic space known as the:

  1. Mediastinum
  2. Metatarsal
  3. Metacarpal
  4. Mesentery
Show answer and solution

Correct answer: A. Mediastinum

1. The space lies medially, between the two lungs. 2. It holds the heart and the great vessels. 3. That space is the mediastinum. _Source: OpenStax Anatomy and Physiology 2e, Chapter 19, The Cardiovascular System: The Heart._

The human heart contains chambers numbering:

  1. 6
  2. 4
  3. 2
  4. 3
Show answer and solution

Correct answer: B. 4

1. Each side has one upper chamber and one lower chamber. 2. There are two sides in all. 3. So the heart has 4 chambers. _Source: OpenStax Anatomy and Physiology 2e, Chapter 19, The Cardiovascular System: The Heart._

Deoxygenated blood is pumped into the pulmonary trunk by the:

  1. Right ventricle
  2. Right vestibule
  3. Right ventricule
  4. Right vertebra
Show answer and solution

Correct answer: A. Right ventricle

1. The blood is heading for the lungs to pick up oxygen. 2. It is pushed there by a lower chamber on the right. 3. That chamber is the right ventricle. _Source: OpenStax Anatomy and Physiology 2e, Chapter 19, The Cardiovascular System: The Heart._
