Organ System Concept Map

Respiratory System

Structures

Upper Respiratory Tract

Nose

Warms and moistens air

narrower nostrils alter airflow in such a way that the mucus-covered nasal membrane can warm and humidify incoming air more efficiently

Pharynx

Passageway for air

the circular muscles form constrictions that help push food to the esophagus and prevent air from being swallowed

Larynx

Air distribution

Lower Respiratory Tract

Trachea

Passageway for air to and from lungs

Made up of C-shaped rings to protect and maintain the open airway

Bronchial Tree

Air distribution and exchange of gas

Lungs

Pulmonary ventilation

Function

Respiration (Breathing)

Inspiration

Expiration

Circulatory System

Structures

Heart

Blood

Blood Vessels

Function

Transportation of blood

How do the 2 body systems work together

They work together to circulate blood containing oxygen throughout the body

Plasma holds CO2

RBC/Hemoglobin binds O2

Structures Shared?

Lungs

Blood

Is one system required for the other to function

Yes, without the respiratory system, blood would be useless.

O2 blood -> organs+tissues via arteries

De-O2 blood -> heart for replenishment via veins
