ANAPHY: U11.1 Respiratory System (General & Functions)

Oxygenation

Process of transporting O2 from the atmospheric air until it reaches the body cells‬

1. Gas Exchange System (Respiratory)

2. Gas Carrying System (Hematology)

3. Gas Pumping System (Heart)

4. Gas Transport System (Circulatory)

4 Subsystems Involved in Oxygenation

Structures that brings O2 & removes CO2 from the blood

What structures is the Respiratory System consisted of?

Breathing/Respiration

What is critical for homeostasis?

Upper Respiratory Tract (URT) & Lower Respiratory Tract (LRT)

2 Main Parts of the Respiratory System

ENPhaL

Acronym for the structures in the URT

External Nose, Nasal Cavity, Pharynx/Throat, Larynx/Voice Box

4 Structures in the URT

TraBroLu

Acronym for the structures in the LRT

Trachea/Windpipe, Right & Left Bronchi, Right & Left Lungs

3 Structures in the LRT

Respiration & Gas Transport

2 Main Functions of the Respiratory System

Respiration

One of the main functions of the respiratory system; has two broad aspects (ventilation & respiration)

Ventilation & Respiration

2 broad aspects of respiration

Ventilation

One of the broad aspects of respiration; movement of air into and out of lungs

Respiration

One of the broad aspects of respiration; diffusion of gases across cell membranes, subdivided into external & internal respiration

External & Internal Respiration

2 types of respiration

External Respiration

One of the types of respiration; movement of gases between atmospheric air in lungs & the blood

Atmospheric air in lungs & the blood

In external respiration, movement of gases occurs between what?

Internal Respiration

One of the types of respiration; movement of gases between blood and body's cells

Blood & Body’s Cells

In internal respiration, movement of gases occurs between what?

Gas Transport

One of the main functions of the respiratory system; in which O2 & CO2 travel in the blood to and from cells

O2 & CO2

What gases are transported in the Respiratory System?

PROVC

Acronym for 5 Other Functions of the Respiratory System

1. Protection

2. Regulation of Blood pH

3. Olfaction

4. Voice Production

5. Production of Chemical Mediators

5 Other Functions of the Respiratory System

Regulation of Blood pH

One of the 5 other functions of the Respiratory system; in which CO2 levels are changed

CO2

Levels of what gas regulates blood pH?

Production of Chemical Mediators

One of the 5 other functions of the Respiratory system;  Angiotensin-converting enzyme (ACE) regulates BP

Angiotensin-Converting Enzyme (ACE)

What specific protein produced by the Respiratory System regulates blood pressure?

Voice Production

One of the 5 other functions of the Respiratory system; air moving past the vocal cords make speech and sound possible

Olfaction

One of the 5 other functions of the Respiratory system; sense of smell when airborne molecules pass the nasal cavity

Protection

One of the 5 other functions of the Respiratory system; respiratory system provides defense against the microorganisms
