Respiratory System

The main function of the respiratory system is the exchange of gasses - oxygen enters the body and carbon dioxide is removed.

the smallest air passageways coming off of the bronchi

Trachea

Pharynx

flap of elastic cartilage attached to the larynx that closes when food passes by

Alveoli

long term or constant disease or disorder

a sheet of internal skeletal muscle that pulls and pushes against the lungs as we inhale and exhale

a hollow tube (wind pipe) that connects the larynx to the right and left bronchus

short term illness or disease

hollow muscular organ which holds the vocal cords (voice box) which produce sound

Nose or nasal cavity

the 2 major air passages leading from the trachea to the lungs

1. A muscle that separates the abdominal cavity from the thoracic cavity & 2. Pushes and pulls against the lungs as we breathe

Both systems share the pharynx and the mouth

Bronchus

the lungs

the air sacks at the end of the bronchioles where the gas exchange takes place

tiny hair-like structures that line your respiratory pathways & filter the air we breathe

the muscular system uses oxygen which is brought into the body through the respiratory system; the diaphragm (a muscle) helps to bring air into and out of the l

the blood from the circulatory system has to pass through the lungs where carbon dioxide is released from the blood and oxygen is picked up into the blood

both systems share the pharynx and the mouth

the passage that leads from the cavities of the nose and mouth to the larynx

the organ that carries out the exchange of oxygen and carbon dioxide
