Respiratory System

Question 1

What are the parts of the UPPER TRACT of the respiratory system?

Answer 1

Nose, Paranasal Sinuses, Pharnyx, Larynx

Question 2

What are the parts of the LOWER TRACT of the respiratory system?

Answer 2

Trachea, Bronchi, Lungs

Question 3

What are the systems involved in the CONDUCTING zone of the respiratory system

Answer 3

The Nose - allows air into the nasal cavity

Pharynx - Muscular Tube that connects respiratory and digestive systems

Larynx - Cartilaginous chamber that connects pharynx to trachea keeps food and drink out of airways, produces sound

Trachea - Tube of rins connecting larynx to bronchi pseudostratified columnar et to move mucous

Bronchi - Transports air to the lungs. Right is wider and more vertical

Terminal Bronchiole - End of conducting zone transport air from segmented bronchii

ALL HAVE CILIATED PSEUDO-STRATIFIED ET

Question 4

What are the parts of the RESPIRATORY Zone of the Respiratory System

Answer 4

Alviolar Duct - thin-walled tube that transports air from terminal bronchi to lungs gas exchange

Alveolus - Type 1: Simple squamous ET for gas exchange
Type 2: secretes pulmonary surfactant to reduce surface tension And alveolar microphages to remove debris

Lungs - Cone-shapes organs that perform gas exchange

All have SIMPLE SQUAMOUS EPITHELIAL TISSUE

Question 6

What is the space around the lungs that is filled with serous fluid?

Answer 6

Pleural Cavity

Question 7

What is the difference between the two kinds of pleura

Answer 7

The Parietal Pleura is the outermost layer that connects to the thoracic wall, the visceral pleura that covers the surface of the lungs
