Your Task:

Go to the following website;

http://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBookAnimalTS.html

…where the relationship between cells, tissues, organs and systems is concisely discussed and the important information regarding this topic is given. Knowledge and understanding of the information presented here will hold you in good stead throughout your biology studies. Some of it is review from previous years of study, but extended to include new terms and more specific examples. After looking at the website, you should create notes to respond to the following learning objectives extracted from the site:

Learning Objectives

•  Be able to list the major functions of each of the four major animal tissue types.

•  Distinguish between simple and stratified epithelial tissue.

•  Compare and contrast the different types of connective tissues: loose, dense, fibrous, cartilage, bone, blood, adipose. Be able to list the function of each type.

•  Know the three types of muscle and be able to differentiate them visually and according to their functions.

•  Be able to diagram a typical neuron and its three areas: dendrite, axon, and cell body.

•  Know the characteristics of the various types of animal tissues. Learn the types of cells that compose each tissue type and be able to give some examples of organs that contain significant amounts of each tissue type.

•  Detail the functions carried out by epithelial tissue and state the general location of each type.

•  Be able to discuss the meaning of the term gland, cite three examples of glands, and state the extracellular products secreted by each.

•  Describe the basic features of connective tissue, and explain how the cells of this tissue type enable connective tissue to carry out its various tasks.

•  List three of the functions of blood.

•  List two functions of bone and/or cartilage.

•  Distinguish among skeletal, cardiac, and smooth muscle tissues in terms of location, structure, and function.

•  Muscle tissues contain specialized cells that can contract.

•  Neurons are organized as lines of communication

You will note that there are review questions at the bottom of the webpage… Though the answers are given, could you have confidently answered the questions? If not, ask now to clarify anything you are not sure of.
