About This Quiz & Worksheet

Autonomic breathing is what controls our ventilation: it allows us to breathe without having to think about it. Look over the printable worksheet to learn more about how this process works, then test yourself with questions about the biological terms and effects in the interactive quiz.

Quiz & Worksheet Goals

Use these assessment tools to assess your knowledge of:

  • The primary stimulant for ventilation
  • Sensitivities of the central chemoreceptors
  • What the medulla oblongata does for the ventilation process
  • The effects of hypercapnia

Skills Practiced

This worksheet and quiz let you practice the following skills:

  • Knowledge application - use your knowledge to answer questions about the medulla oblongata and its involvement in ventilation
  • Critical thinking - apply relevant concepts to examine information about autonomic breathing in a different light
  • Information recall - access the knowledge you've gained regarding hypercapnia and its effects on breathing

Additional Learning

To learn more about how our bodies undergo ventilation, review the corresponding lesson on autonomic breathing. This lesson covers the following objectives:

  • Explores the regulation of ventilation
  • Identifies the relationship between homeostasis and ventilation
  • Examines the parts involved in autonomic breathing, such as the medulla oblongata
  • Discusses the problems that can occur when the respiratory system goes awry
