types of respiration - CORRECT ANSWERS- external, internal, cellular
External respiration is the breathing process. It involves inhalation and
exhalation of gases.
Internal respiration involves gas exchange between the blood and body cells.
Cellular respiration involves the conversion of food to energy.

Sacromere - CORRECT ANSWERS- unit of a muscle fiber
what increases hemoglobin - CORRECT ANSWERS- high altitudes
function of surfactant - CORRECT ANSWERS- Thin layer of fluid that covers
the alveoli.
Reduces surface tension of the fluid layer lining the alveoli, preventing the
alveoli from collapsing during exhalation.
Type II alveolar cells - CORRECT ANSWERS- secrete surfactant
