Answers
Describe the path of food did the digestion system - Answer-The food enters the mouth
(oral cavity) and teeth, tongue, and salivary glands help break down the food into
smaller pieces. The food then travels to the esophagus. Esophagus transport the food
to the stomach. Here, there is a muscular sac that contains acid and enzymes. The
stomach contracts to break down feet. Once the feet leave the stomach it goes to the
small intestines. The small intestines continue to break dancing in absorbs the nutrients.
The 15 goes to the large intestines which absorb the water from it and out of the rectum.
What is a presumptive test - Answer-It's a test that can't confirm if it is something but if
it's likely something.
What are limitations of presumptive test - Answer-It can only tell if something is likely to
be something. They can also be a false positive.
Why does an autopsy include an examination of all the body systems and not just a
suspected cause of death - Answer-They need to perform aunt has sent out information
of how they died is left out. If the victim is in an accident and has had, a toxicology
report could be important because alcohol could've played a role in the head trauma
and how the accident occurred.
What are two reasons why determining the cause of death could be difficult - Answer-
Multiple cause of death can I have the same effect on a person
Not now I'm back on information on the person can make it easy to miss something
important since I don't know anything specific to look for.
Why is the turning the physiological time of death often difficult - Answer-The body will
start decomposing after it dies and it's hard to determine if the body died without a
witness.
How much toxicology be important to other bio medical professionals outside of
forensics - Answer-Toxicology can be important to diagnose a health issue from drugs
or if they had taken some before an operation that you can't have drugs before.
, How is it forensic chemist so much for forensic toxicologist - Answer-They both study in
normality of certain things to figure out a problem
How is a forensic chemist different from a forensic toxicologist - Answer-Forensic
toxicology studies the body/substances in the body and forensic chemist study objects
in materials
What does the nervous tissue look like - Answer-One large cell with branches
surrounded by smaller cells
What does epithelial tissue look like - Answer-Mini round south side by side above other
cells in no order that are circular
What does muscle tissue look like - Answer-Mini fat cells that are scattered
What does connective tissue look like - Answer-Mini cells of different shapes close
together
How is it possible that our cell types are so different when they carry the same DNA -
Answer-The cells in the human body is OK the same DNA but don't have the same job
or function. Depending on their function determines what they look like. The signals
around the cell activate the parts of the cells DNA used.
What's the function of the brain - Answer-It controls thought, behavior, emotion,
memory, breathing and heart rate
What is the function of the frontal lobe - Answer-It's responsible for planning, organizing
incoming information. It also controls behavior and emotion
What is the function of the Parietal lobe - Answer-It intregates sensory and visual
information
What is the function of the temporal lobe - Answer-It is used for processing language
and storing information in the long-term memory
What are the key components of completing an autopsy. - Answer-1. Take
measurements
2. Identify person
3. Document different asspects
4. Get your tools ready
5. Internal exam
6. Digestion Exam
7. Sample Collection
8. Brain Examination
What is cause of death - Answer-Death directly caused by injury, trauma, or disease
