1. What would you observe if you could travel through the human digestive tract?
Any missing assignments on digestive system.
1. I will be here after school both today and Thursday, until 4 pm.
Which organs do both chemical and mechanical digestion?
Starred thought of the Day
*No matter how far you go in life, remember where you came from.
Today we worked on clicker questions based on the information from what we know about the digestive system (15.1 –> 15.4 in your textbook. Questions are listed below.
1. An Issue with which part of your digestive system would affect absorption of nutrients?
c. Small Intestine
d. Large Intestine
2. A disease that affects the liver and gall bladder would probably affect what macromolecule type?
Since we know that the liver and gall bladder are involved with Bile, we need to go a step further. Bile is involved with breaking down fats.
3. Ulcers are a condition affecting the stomach. What do you think causes an ulcer to form?
Ulcers are formed from problems with the mucus cells that protect the stomach. If the pH becomes too acidic or not enough acid is produced, Ulcers would form in the stomach.
4. The Large Intestine does chemical digestion.
5.A virus that affects absorption of water is placed into the vili of the small intestine. (It will not move elsewhere). This will cause the organism to have diarrhea?
False- diarrhea is a problem with absorption of water in the LARGE intestine.
6. What would happen to an individual who was forced to have their pancreas removed?
The individual would probably die, due to a number of factors. The pancreas produces pancreatic juices, which work to break down molecules chemically and neutralizes the pH of the items in the small intestine. An individual with no pancreatic juice may not be able to get enough nutrients because the carbohydrates, lipids, and proteins would be too big to be absorbed. Also, the fluid in the small intestine may be too acidic.
7. The teeth help in chemical digestion
True/False- While the teeth do not directly complete chemical digestion, they help break down particles for a larger surface area/volume so that chemical digestion can occur more efficiently.
