Respiratory System Upper Tract Anatomy Nose -Nose hairs Physiology Where air enters and leaves the respiratory system Trap dirt, dust and the bacteria that live on them

Respiratory System Upper Tract Anatomy Nasal Cavities -mucous membrane --cilia covering membrane Physiology -Produce mucus to provide warm moisture to the air entering the body -( filter / attract ) particles and push them to pharynx

What do you see?

Respiratory System Upper Tract Anatomy Sinuses Physiology -air spaces in skull to reduce weight -open into nasal cavities -also lined with mucous membrane *Any mucous membrane can become infected or inflamed. In your sinuses this condition is know as sinusitis. Sinus headaches occur when the passage to the sinus is blocked with mucus or inflamed tissue.

Respiratory System Upper Tract Anatomy Pharynx (Throat) -nasopharynx -oropharynx -laryngopharynx Physiology top part of your throat where your nasal cavities drain, (blocked by soft palate when you swallow unless you laugh while you are swallowing- this results in food or liquid coming out of your nose) middle part of your throat into which your mouth opens the lower part of your throat Link

Where is the nostril, nasal cavity, pharynx, and sinus?

Respiratory System Lower Tract Anatomy Larynx Physiology Houses vocal cords “voice box” Important for swallowing, coughing, vomiting and defecating f

Respiratory System Lower Tract Anatomy Larynx -thyroid cartilage (Adam’s apple) Physiology flexibility and protection of larynx

Respiratory System Lower Tract Anatomy Larynx -glottis -epiglottis Physiology opening through which air passes a flap of tissue that covers your glottis when you swallow and blocks food from getting into your larynx

Respiratory System Lower Tract Anatomy Larynx -vocal cords Physiology Sound production Watch the Steven Tyler movie

Respiratory System Lower Tract Anatomy Trachea (windpipe) Physiology passage way for air into lungs, cilia catch impurities

Respiratory System Lower Tract Anatomy Bronchial Tree -Bronchi -Bronchioles -Alveoli Physiology branched airways leading from the trachea to the microscopic air sacs in the lungs carries air into lungs smaller branches off of bronchi smallest parts of respiratory system, involved in gas exchange, surrounded by capillaries

Respiratory System Lower Tract Anatomy Lungs -pleural membranes Physiology soft, spongy, organs encase the lungs, involved in regulating pressure in the lungs Link

Where is the pleural membrane, primary bronchus, secondary bronchus, tertiary bronchus?

Summary: Where is the bronchus, epiglottis, larynx, trachea,?
