Active Reading Guide – Part One
5.1 Tissues and Their Functions
To start, what is a tissue? (p. 106)
There are 4 types of tissues the book talks about in section 5.1. What are they? Briefly describe them.
1.
2.
3.
4.
Epithelial Tissue
They have three different functions:
1.
2.
3.
These tissues are classified according to their shape and number of cell layers. These are introduced on
pg. 107 but there is an awesome diagram on page 108. What are all they? Organize them into a table.

Got those down? Flip back to 106 and name the three types of cell junctions and define them in 10
words or less. Check out figure 5.4 on page 109 for a pictorial representation.

Connective Tissue
So, what is Connective Tissue again?
The book mentions 6 different connective tissues. Again, name and describe in 10 words or less each.
1.

6.
Define the following:
-
Fibroblasts:
-
Collagen Fibers v. Elastin Fibers
-
Chondrocytes:

Go back to Cartilage (this is covered a lot) and find the three italicized words. Name and define those.
1.
2.
3.
Muscle Tissue
Muscle fibers contain specialized proteins, _________________ and _________________ that cause
cells to contract when signaled by nerve cells.
There are 2 different ways muscle tissue functions: 1.
2.
And There are 2 types, defined by how they look: 1.
2.
Jot down some details in the space below about the types of muscle mentioned in the section, give
some examples of what types are what, any tips to help you remember etc.

Nervous Tissue
Nervous tissue is composed of cells called ___________________ that do what?
What are these…
Support cells: ________________________
Chemicals by which nerves communicate: ________________________________
Removes foreign substances from nervous tissue: __________________________________
Neurological cells that synthesize myelin: _________________________ and ____________________
(PS, what is myelin??) __________________________________________________________________
Bring nutrients to neurons: ______________________

5.2 Body Cavities and Membranes
The two main cavities are the _______________ cavity and the __________________ cavity.
The cavity at the front of the body consists of two further cavities: name them and describe them
1.
2.
And what separates these two cavities? ________________________
How about the other one? The ________________ cavity or back cavity consists of…
1. _________________________ which is inside the _________________ and houses the
__________________.
2. ____________________________ is formed by the ____________________ and contains the
_____________________.
Body membranes =
There a 5 of these; 3 are Epithelial membranes: 1.
The other two are made up of Connective Tissue: 1.
2.
3.
2.
The pericardium and peritoneum are a special type of membrane called _______________ membranes
(a type of serous membrane). What is the difference between them?

5.3 Organs and Organ Systems
Organs =
Organ systems =
So, back to the levels of organization, what are they? (Starting at atoms  organism)
AND can you relate it to a specific example? (Hint: Figure 5.10)
This may not be necessary to have down 100% right now, but you’ll have to know them in the future.
What are the 12 organ systems?
1. _____________________
2.______________________
3._______________________
4. _____________________
5.______________________
6._______________________
7. _____________________
8. ______________________
9. _______________________
10. ____________________
11. _____________________
12. ______________________
What’s the word that means that the organ systems work together and need each other to perform
specific functions? ________________________

5.4 Homeostasis
What is homeostasis? Why is it an important ability to have?
The other important concept in this chapter is feedback. In your own words, what’s feedback?
There are two types of feedback:
1. _______________________ is when the product of a process inhibits the process. This, in other
terms means: _______________________________________________________________________
__________________________________________________________________________________
An example of this is:
2. _______________________ occurs when the product the process intensifies the process. In other
terms, this means: _____________________________________________________________________
____________________________________________________________________________________.
An example of this is:
