|
Unit Review
Here is what we have learned from this unit:
- The digestive tract includes the digestive tract and its
accessory organs, which process food into molecules that
can be absorbed and utilized by the cells of the body.
- Food undergoes three types of processes in the body: digestion,
absorption, and elimination.
- The digestive system prepares nutrients for utilization
by body cells through six activities, or functions: ingestion,
mechanical digestion, chemical digestion, movements, absorption,
and elimination.
- The wall of the digestive tract has four layers or tunics:
mucosa, submucosa, muscular layer, and serous layer or serosa.
- Regions of the digestive system can be divided into two
main parts: alimentary tract and accessory organs.
- The alimentary tract of the digestive system is composed
of the mouth, pharynx, esophagus, stomach, small and large
intestines, rectum and anus.
- Associated with the alimentary tract are the following
accessory organs: salivary glands, liver, gallbladder, and
pancreas.
Quiz
To test how much you have learned from this unit, two types
of quizzes have been created. The first type is a multiple-choice
quiz. The quiz questions are grouped into several sets of
two questions each to reduce the size of the content on each
page. When you finish the questions in one set, click the
Next button ( a right-pointing arrow icon located in the Title
Bar) to proceed to the next page.
The second type is a drag-and-drop quiz, in which, by using
the mouse pointer, you drag a textual or graphic element to
a target area to show your knowledge of the material covered
in the unit. Note that the object you are dragging will snap
back to its original position until it is placed in the correct
target area. Try to drag the object as close to the center
of the target area as possible so that the object will snap
to the target area when you chose a correct answer.
