Answer the following questions on the lined paper provided:
6. (10) What is tissue fluid, where is it found, how is it produced,
and what are its functions?
7. (20 points) There are many tissues in the body that are characterized
by the production of mucus. What exactly is mucus and what is it made of?
Also, describe the sources of mucus in the upper respiratory tract and stomach
and compare and contrast the functions of mucus in these two locations.
8. (40 points) Throughout this course we have stressed the relationship
between histological structure and physiological function. Choose one of
the organ systems listed below and discuss how the structure of the tissues
and cells that comprise the system contribute to the functions performed
by the system. As appropriate discuss the relationship between structure
and function at the sub-cellular, cellular, tissue, and organ levels. Be
sure to discuss the role and organization of the epithelia, glands, connective
tissues, and other types of tissues found in the system. Make your answer
as complete as possible.
a. Nervous system
b. Cardiovascular system
c. Lymphoid (immune) system
