Cell structure and function
Nerve cells/neurons: Go to https://faculty.washington.edu/chudler/cells.html
1. What are nerve cells specialized to do?
2. Draw a nerve cell below:
3. How is the nerve cell’s structure related to its function?
Red blood cells – carry oxygen in the blood
Go to: http://www.sicklecelldisease.org/index.cfm?page=about-scd
1. What shape is a normal red blood cell? (Look at yesterday’s notes)
2. What shape is a sickled red blood cell?
3. Why is a change in structure a bad thing in this specific situation?
Cells are organized into tissues. Go to: http://www.siumed.edu/~dking2/intro/4basic.htm
What are the four basic tissue types? What are their functions?
1.
2.
3.
4.
Click on each tissue type and look at the pictures. Do they all look the same? Why or why not?
Homeostasis. Go to:
http://www.bbc.co.uk/schools/gcsebitesize/science/edexcel/responses_to_environment/homeostasisre
v1.shtml
What is homeostasis?
What is osmoregulation?
What are three ways that water is lost from the body during osmoregulation?
What are three ways that the body increases or decreases heat loss from the body?
What are hormones?
What does insulin do?
Why can diabetes be treated through insulin injections?
Osmoregulation in other organisms. Go to: http://www.petmd.com/fish/care/evr_fi_osmoregulation
How is osmoregulation different in marine fish versus freshwater fish? Use the words hypertonic,
hypotonic, and/or isotonic in your answer.
More homeostasis. Go to: http://www.mhhe.com/biosci/genbio/maderbiology/supp/homeo.html
Explain how the respiratory center is involved in maintaining homeostasis.
How are buffers used to control pH?
