Respiratory System 23-24

What is the main role of the respiratory system?

• To provide oxygen to the blood while removing carbon dioxide from the body

• The maintain blood pH

• To provide structural support to the thoracic cavity

• To allow for more efficient perfusion of the heart

The Sphenoid Sinus...

• Is located within the sphenoid bone

• Drains mucus towards the Frontal Sinus

• Does not contain any cilia

• Drains mucus through the Eustachian Tubes

The Mucosal Membrane is made up of:

• Ciliated Pseudostratified Columnar Epithelium

• Non-Ciliated Squamous Epithelium

• Ciliated Stratified Columnar Epithelium

• Non-Ciliated Simple Squamous Epithelium

Hair-like projections which clear mucus from the airways

• Cilia

• Goblet Cells

• Mucosal Epithelium

• Common Nares

Mucus producing cells in the mucosal membrane

• Cilia

• Goblet Cells

• Mucosal Epithelium

• Common Nares

All of the mucus produced within your respiratory system is swept to the pharynx to be swallowed. This process is called:

• Mucociliary Escalator

• Mucosal Mamba

• Mucus Ciliated Extraction

• Ciliary Mucosal Adduction

Which of the following best describes Gas Exchange in the Pulmonary Circuit?

• Oxygen enters the blood from the lungs while carbon dioxide enters the lungs from the blood

• Carbon Dioxide enters the blood from the lungs while oxygen enters the lungs from the blood

• Due to partial pressure gradients, oxygen is forced into the lungs

• Due to partial pressure gradients, oxygen is forced out of the blood

Which of the following is NOT a role of the mucosal membrane?

• Moistens incoming air

• Warms incoming air

• Traps particulates and pathogens

• Filters out some of the incoming carbon dioxide
