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.
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.
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.
