Mt Respiratory Anatomy

Front 1

nose

Back 1

lined with mucouse membranes and hair to filter, moisten, and warm the entering air

Front 2

nasal septum

Back 2

partition separating right from left nasal cavities

Front 3

paranasal sinuses

Back 3

air cavities within the nasal cavities that open into the nasal cavities

Front 4

pharynx (throat)

Back 4

passageway for food and air. Air moves from the nasal cavities to the pharynx then the larynx. Food enters the pharynx from the mouth and moves into the esophagus.

Front 5

adenoids

Back 5

lymphoid tissue located behind the nasal cavity.

Front 6

tonsils

Back 6

lymphoid tissue located in the posterior pharynx or behind the mouth

Front 7

larynx (voice box)

Back 7

houses the vocal cords

Front 8

epiglottis

Back 8

flap of cartilage that covers the opening of the larynx keeping food from entering the larynx during swallowing

Front 9

Adam's Apple (thyroid cartilage)

Back 9

largest ring of cartilage in the larynx

Front 10

trachea (wind pipe)

Back 10

passageway for air to the bronchi

Front 11

bronchus

Back 11

one of two branches of the trachea that conducts air into the lungs, where it divides and subdivides (bronchial tree).

Front 12

bronchioles

Back 12

smallest subdivision of the bronchial tree

Front 13

alveolus

Back 13

air sacs at the end of the bronchioles. Through the alveolar walls and the capillaries oxygen and carbon dioxide are exchanged.

Front 14

lungs

Back 14

two sponge-like organs in the thoracic cavity. The right lung consists of 3 lobes, the left lung has two lobes

Front 15

pleura

Back 15

serous membrane covering both the lungs and lining the thoracic cavity

Front 16

diaphragm

Back 16

aids in the breathing process, it is the muscular separation of the thoracic and abdominal cavities

Front 17

mediastinum

Back 17

space between the lungs. The heart, esophagus, trachea, great blood vessels, and other structures are contained here.
