function of nasal cavity
warms, moistens, and filters incoming air.
what is nasal cavity composed of?
lined with ciliated mucous membrane. Sweeping motion moves particles toward the
throat; passageway for food to the esophagus and for air
1. BP decreased (lowered kidney perfusion)
2. Juxtaglomerular cell of kidney releases renin
3. Renin converts Angiotensinogen to Angiotensin I
4. Angiotensin I converted to Angiotensin II
5. Angiotensin II: vasocontricts, stimulates adrenal cortex to rele

lungs are in balance, what happens?
inhalation ceases or no further air flow
