Define the following terms, Digestion
The process by which an
organism breaks down its food into small units which can be absorbed
Define the following terms
Vitamin
chemical substance essential for the normal working of the human body
For the TONGUE, answer the following questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract? If it is a part of the digestive system, what iS(are) its function or functions?
The tongue is a part of the digestive system and a part of the digestive tract. It moves the food around in the mouth to form the bolus. It also provides a sense of taste, but that’s more a
part of its nervous system function.
For the LARYNX, answer the following questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract?
If it is a part of the digestive system, what is (are) its function or functions?
The larynx is not a part of the digestive system
For the TRACHEA, answer the following questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract?
If it is a part of the digestive system, what is (are) its function or functions?
The trachea is not a part of the digestive system.
For the pancreas, answer the following questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract?
If it is a part of the digestive system, what is (are) its function or functions?
The pancreas is a part of the digestive system but not a part of the digestive tract. It has two
main functions. It makes several digestive juices which are squirted into the small intestine as
chyme passes through the pyloric sphincter. In addition, it also produces a base to neutralize the
stomach acid. The base is called sodium bicarbonate, but you do not have to know that.
For the stomach, answer the following questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract?
If it is a part of the digestive system, what is (are) its function or functions?
The stomach is a part of the digestive system and the digestive tract. It churns and mixes the
food with gastric juices. The gastric juices contain stomach acid which destroys bacteria that
might have been eaten with the food and helps dissolve the food. The gastric juices also contain
some digestive chemicals that start the chemical digestion of the food. This turns the bolus of
food into chyme.
For the small intestine, answer the following
questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract?
If it is a part of the digestive system, what is (are) its function or functions?
The small intestine is a part of the digestive system and the digestive tract. It chemically
digests the food and allows the nutrients to be absorbed through its lining.
For the rectum, answer the following questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract?
If it is a part of the digestive system, what is (are) its function or functions?
The rectum is a part of the digestive system and the digestive tract. It pushes food out of the
body through the anus
For the salivary glands , answer the following questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract?
If it is a part of the digestive system, what is (are) its function or functions?
The salivary glands are a part of the digestive system. Technically, they are not part of the
digestive tract because food does not pass through them. Don’t worry if you got that wrong.
They put saliva in the mouth. The saliva partially digests the food, but it also lubricates the
mouth and makes it easier for the tongue to form the bolus.
For the pharynx, answer the following questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract?
If it is a part of the digestive system, what is (are) its function or functions?
The pharynx is a part of the digestive system and the digestive tract. It pushes food into the
esophagus
For the esophagus, answer the following questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract?
If it is a part of the digestive system, what is (are) its function or functions?
The esophagus is a part of the digestive system and the digestive tract. It pushes food down
into the stomach
For the lungs , answer the following questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract?
If it is a part of the digestive system, what is (are) its function or functions?
The lungs are not a part of the digestive system.
For the liver , answer the following questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract?
If it is a part of the digestive system, what is (are) its function or functions?
The liver is a part of the digestive system but not a part of the digestive tract. It has many
functions. The most important digestion-related functions are making bile, converting
monosaccharides to glycogen for storage, breaking glycogen down when the body needs energy,
storing amino acids, storing fats, and converting fats and amino acids into monosaccharides
when the body needs energy. The liver has many other functions, but those are the ones I want
you to remember.
For the gall bladder , answer the following questions. Is it a part of the digestive system?
If it is a part of the digestive system, is it a part of the digestive tract?
If it is a part of the digestive system, what is (are) its function or functions?
The gall bladder is a part of the digestive system but not a part of the digestive tract. It
concentrates bile and squirts the bile into the chyme as the chyme enters the small intestine. Bile
is a chemical that aids in the digestion of fats.
For the large intestine , answer the following questions: Is it a part of the digestive system? If it is a part of the digestive system, is it a part of the digestive tract? If it is a part of the digestive system, what is (are) its function or functions?
The large intestine is a part of the digestive system and the digestive tract. It consolidates
undigested food, absorbs water from it, and turns the resulting waste into feces. Bacteria in the large intestine also produce vitamin K.
For the appendix, answer the following questions: Is it a part of the digestive system? If it is a part of the digestive system, is it a part of the digestive tract? If it is a part of the digestive system, what is (are) its function or functions?
The appendix is a part of the digestive system. It is not a part of the digestive tract. You might have thought that it was since it is attached to the large intestine, butit is not. It sort of “hangs” off the large intestine and food never passes through it. Its function is not known.
Many think that it is a highly-specialized disease-fighting organ.
For the anus , answer the following questions: Is it a part of the digestive system? If it is a part of the digestive system, is it a part of the digestive tract? If it is a part of the digestive system, what is (are) its function or functions?
The anus is a part of the digestive system and the digestive tract. It is the opening through which feces exit
What keeps food from going down into your larynx?
The epiglottis covers the larynx when you swallow. It stays open when you breathe.
What would happen to the digestive process if the pancreas stopped making the base that it uses to
neutralize stomach acid?
The digestive process would essentially stop in the small intestine, because the
digestive chemicals in the small intestine cannot work in the presence of acid.
What are the fat-soluble vitamins?
Vitamins A, D, E, and K are fat-soluble.
Which vitamins (fat-soluble or water-soluble) are the most likely to build up to toxic levels in the body if you take too many?
The fat-soluble vitamins are the most likely to build up to toxic levels, as the water-soluble vitamins can be ejected from the body through the urine.
What kind of role do most vitamins play in the body?
Vitamins typically regulate the chemical processes in the body.
Which two vitamins can the body absorb without eating food that contains those vitamins?
Vitamins D and K. Vitamin D is made from sunlight hitting the skin, and vitamin K is made by bacteria in the large intestine.
