Chapter 4 questions:

1.  Drinking eight glasses of water a day keeps the body “lubricated.” From what you know about Exocrine glands, give five specific examples why must we consume so much liquid.

Example:  Breast milk has a base of water, therefore nursing mothers must consume water so the mammary glands will function properly.

2.  Infection in the abdominal cavity often involves the peritoneum (membrane lining the walls of the abdominal cavity).  For instance, a ruptured appendix allows the escape of intestinal contents, loaded with bacteria, into the peritoneal cavity.  This leakage causes a life-threatening infectious condition called peritonitis.   Why do you think it is necessary to operate to take someone’s painful, infected appendix out?

3. If the infected appendix ruptured (burst), what type of medicinal treatment would be necessary? (Remember our infectious disease unit and bacteria…)

4. List two reasons why a plastic surgeon shouldn’t remove all of the adipose tissue from a patient having liposuction.

5. Copy the following list of tissues.  Write what type of junction cells in the tissue would have and WHY?
a.      stomach lining
b.      intestine lining
c.      leg muscle
d.      heart muscle
e.      nervous tissue
f.        taste buds

6. Connective tissue share two characteristics.  First, most connective tissue (except ligaments, tendons, and cartilage) has good blood supply.  Ligaments and tendons have a poor blood supply, and cartilage has no blood supply. Second, connective tissue has an abundance of extracellular matrix—secreted substance and protein/fibers. If these three tissues--ligament, cartilege, muscle--had an injury, which would heal most rapidly?  Most slowly?  WHY?  

7.  What does loose connective tissue do?

8.  What are some similarities between cartilage and bone?  What are some functions of cartilage? How are the functions of cartilage and bone similar?

9.  Nervous tissue makes up the brain, spinal chord, and the nerves. They transmit electrical signals to and from the brain and spinal chord. What are the five senses that sensory neurons transmit?

10. Name three diseases that are caused by some form of nerve dysfunction.
