Bio 20 Respiratory System

Front 1

Alveoli

Back 1

gas exchange structure within mammalian lungs; tiny air pocket with walls made of a membrane that is a single cell thick, allowing for exchange of respiratory gasses.

Front 2

Bronchiole

Back 2

In a mammal, the passageway that branches from he bronchi into the separate lobes of the lungs; divides into smaller and smaller passageways that carry air into all portions of the lungs.

Front 3

Bronchus (bronchi)

Back 3

In a mammal, the passageway that branches from the trachea into the lungs, with one bronchus carrying air into each lung.

Front 4

diaphragm

Back 4

In mammals, a muscle layer that separates the region of the lungs (thoracic cavity) from the region of the stomach and liver (abdominal cavity) contraction contributes to the inspiration (inhalation) by increasing the volume of the thoracic cavity.

Front 5

epiglottis

Back 5

In mammals, flap of cartilage located over the entrance to the trachea (called the glottis) closes during swallowing to prevent food from entering the respiratory tract.

Front 6

glottis

Back 6

In mammals, the opening of the trachea through which air enters the larynx.

Front 7

Larynx

Back 7

In mammals, a structure within the upper respiratory tract that contains the vocal cords; also commonly known as the voice box

Front 8

Lung

Back 8

The organ through which a person goes through external respiration.

Front 9

Nasal passages

Back 9

Passage from the nostrils to the back of the throat through which air enters the body; serves to warm, moisten, and clean incoming air; lined with ciliated cells and mucus-secreting cells, also called the nasal cavity.
