29
Q
  1. Give the letter and names of the two organs shown in the diagram through which food does Not travel
A

C pancreas G liver

54.WKSTDSecCTheDigestiveProcessBegins

30
Q

A

A esophagus B stomach C pancreas D rectum E small intestine F large intestine
54.WKSTDSecCTheDigestiveProcessBegins

31
Q
  1. What specifically is the name of the area of organ C shown? In general, could organ C perform in functions without organ B? Explain
A

C Duodesumn of the small intestine, B is the pancreas, which produces enzymes that aid in chemical digestive. Without those enzymes,chemical digestion could not be completed, C the small intestine would be unable to asorb small nutrients molecules in blood stream
54.WKSTDSecCTheDigestiveProcessBegins

32
Q
  1. Give the letter and name of the organ through which food is absorbed
A

C small intestine
