Respiratory System (ch 14)
Know these parts (where they are in body and brief function of each):
Nares
Nasal conchae
Pharynx
Larynx
Trachea
Bronchi (1o, 2o, 3o)
Bronchioles
Alveoli
Right lung (3 lobes)
Left lung (2 lobes)
Diaphragm
Main function of respiratory system is...
What are cilia and why are they in our trachea?
Movement of intercostal muscles and diaphragm during inspiration and
expiration…
O2 and CO2 in the alveoli during inspiration and expiration…
Transportation of O2 on what kind of cells? Specifically on what molecule…
Know difference between internal and external respiration… (and where do they
each occur in the body)?
Effect of smoking on cilia…
What is surfactant?
What type of WBC do we have in our alveoli? Why are they there?
Dig. System (ch 16)
Glands in the mouth…
What are the enzymes called and what do they break down?

body… AND the name of the enzyme responsible.
Carbohydrates
Proteins
Fats
What helps our body to break down or digest the foods we eat?

Sphincters on top of stomach (by esophagus) and bottom of stomach, by sm.
Intestine…
Food we eat is called 3 different things as it moves through our GI tract…
In what part of the GI tract is it called (a bolus, chyme, feces…)???
Where does protein begin to be broken down or digested? What organ?
Nutrient absorption occurs into our bloodstream mainly in which GI tube?
Three accessory organs to our digestive system?
1.
2.
3.
ALSO… how do each of the accessory organs help us to breakdown food (brief
function of each)
Know the 4 layers of the GI tract. (Mucosa, submucosa, etc…)
What are villi? How are they helpful?
Immune cells in our GI tract help us to kill any bacteria we ingest… what are they
called?
