zymogen
an inactive precursor of an enzyme that must go through a change to be activated is known as a(n)?
they sense temperature
how do thermoreceptors differ from other sensory neurons?
by peristalsis, which is the contraction of smooth muscle to push food forward
how is digesting food moved along the small intestine?
pancreas, bicarbonate
secretions from the _____, called____, neutralize acid from the stomach in the small intestine
use of the somatic nervous system
swatting a mosquito is an example of which of the following?

the muscular valve at the bottom of the stomach that controls the flow of partially digested food into the small intestine is known as the:
tracheal cartilage
what allows the trachea to expand and contract while breathing?
it removes dirt, warms, adds water vapor to the air we breathe
what are some of the benefits of the conducting zone?
sensory organs
what component of the body gathers sensory input and delivers it to the brain?
they are both digestive enzymes
what do amylase and pepsin have in common?
monosaccharides and amino acids
what forms must carbohydrates and proteins take to be absorbed by the small intestine?
to break down protein to amino acids
what is one reason that enzymes are present in the small intestine?
The conducting zone moves air into and out of the lungs, while the respiratory zone moves oxygen and carbon dioxide in and out of the blood
what is the difference between the conducting zone and the respiratory zone?
collect sensory input from the body and external environment
