Respiratory System

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

short term illness or disease

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

Nose or nasal cavity

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

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

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

Bronchus

both systems share the pharynx and the mouth

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

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

Alveoli

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

the smallest air passageways coming off of the bronchi

Trachea

the lungs

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

Pharynx

Both systems share the pharynx and the mouth

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

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

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

long term or constant disease or disorder
